Subject: Astaxanthin can boost your health
Astaxanthin is a nutrient that has tremendous potential for improving human health, but it's not well known.
Most people have never even heard of astaxanthin, let alone know how beneficial it can be for their health.
Astaxanthin is a uniquely powerful nutrient that can improve your health in ways you never imagined. It's hundreds of times more potent than some of the world's strongest nutrients at stopping oxidative stress, and it offers a wide range of other benefits as well.
There are a variety of natural astaxanthin sources. The most well-known source is the microalgae haematococcus pluvialis, which is often used as a dietary supplement. Other natural sources include shrimp, lobster, and crab. Salmon, trout, and other red-fleshed fish get their pink color from astaxanthin, which they acquire by eating krill and other small crustaceans. Astaxanthin is also found in certain plants, including spirulina and chlorella. In addition, some fungi produce astaxanthin, and it is sometimes added to poultry feed to provide a healthy pigment for the flesh. Astaxanthin is a powerful antioxidant that has a range of potential health benefits. It is thought to protect against heart disease and cancer, and it may also help to reduce inflammation.
- -Unique antioxidant that helps protect from oxidative stress
- -Even shown to reduce risk of cancer
- -Powerful enough to be used in supplements and as food colorings
- -Non-toxic and safe for long term use

Subject: Cholesterol: The good, the bad and dietary cholesterol
LDL cholesterol is known as the awful cholesterol since it is the fundamental wellspring of cholesterol development in the dividers of the veins. Add up to cholesterol level is a blend of LDL cholesterol, HDL cholesterol and different fats in the blood. Dietary cholesterol is the cholesterol found in every creature sustenance, be that as it may, nourishments, for example, eggs, liver, kidney and shellfish, including shrimps and prawns are especially rich in cholesterol. Oils, for example, coconut oil and palm oil additionally contain soaked fat and known to influence blood cholesterol levels to fluctuating degrees, however late proof recommends we require promote logical audit with respect to the degree to which blood cholesterol levels are influenced. No suggestion was made in 2015 for particular breaking points on dietary cholesterol allow as more logical proof was required in regards to the connection between the measure of dietary cholesterol admission and blood cholesterol levels.
- Our body turns cholesterol into hormones, vitamin D and bile acids for digestion. However, high cholesterol can lead to cardiovascular diseases.
- High cholesterol is treated with prescription drugs and dietary changes.
- The effect of dietary cholesterol on blood cholesterol has been controversial.
"The research evidence on this matter, however, has been quite clear for a long time - the amount of cholesterol in the diet does not significantly affect blood cholesterol levels when compared to the fat content of the diet2."

Subject: Medical News Today: Is shrimp high in cholesterol? Nutritional and heart health information
shrimp are rumored to be unhealthy and elevate your cholesterol. Rest assured, shrimp and other shellfish are nutritious foods that can play a part in any diet. shrimp are packed with minerals, so this needs to be considered as a part of some diets that restrict minerals such as sodium. As with all foods, shrimp can be cooked in both healthy and unhealthy ways
- One serving of shrimp contains 189 milligrams of cholesterol, which translates to roughly 60 percent of the total recommended amount of cholesterol per day.
- shrimp are now generally considered safe for people with high cholesterol to eat. They contain a number of useful nutrients.
- What is more damaging to cholesterol and a heart-healthy diet is not the shrimp so much as the way it is prepared.

On a diet and looking for those healthy foods to consume and lose weight? It is important when looking into those healthy foods to make sure they are really healthy. Some cereals can be a convenient and healthy breakfast but watch out for those sugary cereals they can cause a blood sugar spike and a crash before lunch time. Another healthy choice is sushi but beware sushi that is battered and fried can contain 200 more calories and three times the amount of fat.
- Popcorn, cereal, sushi: We love them, and we may tell ourselves they are healthy. But are they? Most of the time, it depends on how they're prepared.
- A crunchy shrimp tempura roll, which is battered and fried and often drizzled with spicy mayo, has about 200 more calories and three times the amount of fat.
- Air-popped popcorn is a healthy, whole-grain, antioxidant-rich snack that's low in calories.

How Much Protein Should You Eat?

Subject: How Much Protein Should You Eat?
Protein is the major staples of a strong diet along with carbohydrates and fats. Eating them in the proper proportions will help you to lose weight or maintain a healthy weight. Despite what you may have heard, most people don't have a problem getting enough protein. The more important thing to focus on is eating the right protein.
So how much protein per day should you eat? The USDA, in their My Food Pyramid guidance system, suggests 0.8g - 1.2g of protein per kilogram of body weight daily. So what the heck does that mean? To determine this for yourself, multiply your weight by 0.45, and that gets you your weight in kilograms. So an 180 lb. The male would weigh 81 kilograms. Multiply that by 0.8 - 1.2 and that person would need about 65g-100g of protein per day.
Proteins are made up of amino acids, one of the main building blocks in our body. They are even found in our DNA. Many are produced by the body (called non-essential amino acids), but others are only obtained from food called essential amino acids. You can get these necessary amino acids from supplements, but the best source is food.
Why are these amino acids so important in burning fat?
Amino acids combine to create structural proteins in the body. Without them, we wouldn't be able to repair and build muscle tissue, which helps keep our metabolism high and helps us burn fat - even resting. Amino acids come from protein sources. If you don't eat enough protein in your diet, you lack the amino acid combination's to keep your body functioning properly.
There are many sources of protein, but not all are good for you. Some protein-rich food also contains a lot of saturated fat. So, you need protein sources that are low in saturated fat but high in the proteins that the body needs to break down and retrieve the essential amino acids.
Here are some examples of lean proteins:- Red meat - Red meat is full of protein. Leaner cuts such as eye of the round will come with less fat. Grass-fed beef is the best when you can find it because it contains fewer hormones and other unhealthy byproducts.
-Fish - Certain fish and shrimp contain protein, as well as other nutrients like omega-3 fatty acids (a member of the "good fats" category). They are good for heart health and overall well-being. Try salmon, mackerel, trout, or tuna.
What is chitosan and how effective is it for weight loss?

Subject: What is chitosan and how effective is it for weight loss?
Chitosan is a compound extracted from the hard shells of shrimps and other crustaceans. While it has many uses, it also claims that it aids in the elimination of excess fat in our bodies which makes it a perfect candidate for inclusion in any weight loss program. It can be ingested in the form of capsules, powder and pills.
How does it work?
Chitosan works by preventing the absorption and storage of fat before it is metabolized in the stomach. Basically, it is a fiber that absorbs fats when they enter the body. Therefore, the fat is broken down and does not get absorbed into the blood stream. Instead, fat and chitosan go through your small intestine or the ileum where they bind with bile acids. They then form an insoluble gel that passes through the large intestine and is excreted out of your body. This means that instead of the fat being absorbed into the blood stream, it is excreted out of the body and no fat absorption means no weight gain.
There is still another way that chitosan helps in weight loss. Since chitosan is a fiber, it promotes cleansing which is important in the process of losing weight.
Another reason this compound seems to work for weight loss is that it makes the body not to crave for fattening foods. It neither starves nor does it make you feel hungry; this is simply because you continue eating fat, the only thing is that the fat does not get absorbed into your blood stream.
Now, since less amounts of fat are entering the blood stream, the body is able to burn the existing fat present in your body. Therefore, your body burns the fat in the body and you constantly lose weight.
Chitosan products contain vitamin C which makes it swell up. This promotes appetite suppression which is very important for weight loss.
Can Low Selenium Affect Thyroid Functions?

Subject: Can Low Selenium Affect Thyroid Functions?
What is thyroid glands
Human thyroid glands are small glands with a very important function. The major function of thyroid glands is to regulate body metabolism.
There are two main hormones produced by thyroid glands; thyroxin (T4) and triiodothyronine (T3). The secretion of these 2 hormones is based on the feedback mechanism of hypothalamus and pituitary glands. These hormones influence every body cells- they control the rate at which your body accumulates and uses fat, help to regulate body temperature and also heart rate. In addition, thyroid glands produce calcitonin, a very important hormone that regulates the amount of calcium in the body. There are the major types of thyroid diseases, Thyroid cancer, Hyperthyroidism, Hypothyroidism and Benign disease. But what is the role of selenium in thyroid functions?
Selenium deficiency is not common in healthy adults, but it is common in people with digestive disorders causing low absorption, or those with severe inflammation arising from chronic infection. Research shows that low selenium does not cause illness by itself, but due to its role in immune functions, it makes a body susceptible to biochemical, nutritional and infectious diseases.
But this does not mean that selenium has no direct influence on thyroid functions. Adequate selenium supports the production of thyroid hormones, protects thyroid glands from the adverse effects of excess iodine in the body, and will also improve body metabolism.
Importance of selenium
Selenium is very important and it is always healthy to ensure your normal selenium level. For example, selenium supplements are used to treat autoimmune thyroid condition. Studies have found that selenium supplementation lowers thyroid inflammation. These findings are backed by the fact that selenium increases thioredoxin reductase and glutathione peroxidase activity, and also lowers the toxic concentration of lipid hydro peroxides and hydrogen peroxides which results from the production of thyroid hormones.
Selenium prevents thyroid tissue damage. Selenium is very important because it lowers the level of thyroid peroxides in the blood. In addition, selenium is vital for conversion of T4 to T3. T3 is the active form of thyroid hormones. Low T3 causes hypothyroidism.
How to obtain selenium?
If you think your body is deficient of selenium, it is good to seek medical care immediately. Thyroid glands are very important for the body functions. Selenium supplement is a good solution to thyroid function. But long term use of selenium supplement would cause other complications such as white blotchy nails, hair loss, gastrointestinal upsets, fatigue, irritability, garlic breath odor, and mild nerve damage. In addition, very high selenium in the body may cause hyperthyroidism. In addition, clinical test for use of selenium supplements has found that it predisposes users to the risk of prostate cancer. Though this has not yet been proven. This makes selenium rich foods the best way to increase the level of selenium in the body. Some of the food rich in selenium includes; crimini mushrooms, shrimp, tuna, cod, scallops, chicken, halibut, salmon, shiitake mushrooms, brazil nuts, lamb eggs, and turkey. Brazil nut is particularly very rich in selenium, taking one or two in a day will significantly improve the selenium level and also boost your immune system.
Is selenium important for thyroid function?
Yes, selenium level is very important and low selenium.
Can Chitosan Really Absorb Fat?

Subject: Can Chitosan Really Absorb Fat?
What is a chitosan
Chitosan is a naturally produced supplement that is recommended by nutrition experts and doctors as a great remedy for weight loss and high cholesterol, which results in a lower risk to develop bothersome cardiovascular problems and facilitates a better looking physique. Chitosan is made from the outer shell of crustaceans, such as shrimp or lobster. The outer shell is processed and a special form of "sugar", also known as a polysaccharide, is obtained. Unlike other types of artificially created sugars, Chitosan possesses unique properties that make it a great addition to a healthy diet for individuals who want to manage their weight and prevent obesity.
How Does Chitosan Work to Facilitate Weight Loss?
Several research studies conducted by nutrition experts and medical professionals specializing in the treatment of obesity reveal the surprising properties of Chitosan in terms of its ability to influence the absorption of fat in the stomach and intestines. Once ingested, Chitosan works in the digestive system by binding excessive fat and making it more difficult to achieve fat absorption. In other words, it limits fat absorption by blocking free fat available for absorption and eliminating it as waste from the human body. Naturally, if fat absorption is limited in this manner, the caloric intake is dramatically diminished, which obviously results in weight loss and a better looking physique.
Chitosan has the Capacity to Bind and Remove Cholesterol
Fat retention and removal achieved by Chitosan after meals is a great feature of this natural supplement that inevitably results in a healthy and progressive weight loss. However, the benefits of Chitosan are also reflected in its positive influence on the cardiovascular health. The fat ingested through meals contains harmful cholesterol, which can accumulate in the blood vessels causing blockages of the blood flow and a higher risk for dangerous cardiovascular problems like strokes or heart attacks. Chitosan traps the excessive cholesterol delivered in the digestive system through daily meals, which results in less cholesterol being circulated in the bloodstream, and an improved blood flow to the brain and heart.
What Are The Benefits Of Vitamin E?

Subject: What Are The Benefits Of Vitamin E?
Vitamin E is composed of eight fat soluble vitamins and it’s available in four different forms. The fat soluble antioxidant can only be obtained in food as a supplement. They help in prevention of oxidative stress in the body and other vitamins.
There are different varieties of foods rich in vitamin E in terms of nutrients density with examples such as:
1. Tofu light, silken with a 25% daily value in every 5.3 mg.
2. Cooked spinach. 10 % DV in 2.1mg.
3. Almonds nuts
4. Roasted sunflower seeds and avocados with about160 calories
5. Shellfish shrimp and rainbow trout fish ranging at 12% DV for 2.8mg
6. Cooked broccoli and cooked butternut squash with about 7% DV for 1.5mg.
Health benefits of vitamin E.
The health benefits come from the vitamins antioxidant property which remove free radicals that damage the cell structure due to its unstable compounds. It improves immunity and reduces cholesterol thereby reducing the risk associated with developing cancer.
Vitamin E prevents the blood platelets from clumping. Heart diseases, sunstroke and coronary artery disorders are prevented through consumption of high levels of vitamin E.
Vitamin E owing to its properties of antioxidant, promotes blood circulation to the scalp which help in reducing fatigue and make capillary walls more stronger for nourished cells.
Vitamin E oil facilitates the healing process and since it’s extremely versatile, the vitamin E absorbed in the epidermis layer is used in treating and preventing sunburns.
Since vitamin E speeds up cell generation, it’s used to treat acne, scars, and wrinkles which makes the skin to appear more younger due to its anti-aging effect.
Vitamin E helps the skin to maintain its natural moist and appear to be more fresh. It’s also used to treat nails and cuticles by applying a few drops of vitamin E on them.
Vitamin E is believed to promote eye health and reduces the risk of eye damage associated with old age by 20%. i.e macular degeneration.
Astaxanthin Protects The Eye And More!

Subject: Astaxanthin Protects The Eye And More!
Astaxanthin is a carotenoid that is commonly found in the marine environment. It is naturally found in salmon, krill, trout, crayfish, shrimp, crustaceans and yeast. It is the chemical that is responsible for the red color in cooked shellfish and salmon meat. The algae Haematoccus has the richest natural source of astaxanthin.
Astaxanthin can also be produced synthetically, but due to the synthetic product consisting of different steriosmers it is not preferred to be used in some cases.
Unlike beta-carotene it has two more oxygenated groups on each of its ring structure, these additional functional groups make it a highly potent antioxidant and give it a configuration that is more polar than that of other carotenoids. Vitamin E has been known as the strongest antioxidant both in topical use in cosmetics and in internal use, but research has shown that astaxanthin has a greater antioxidant strength than Vitamin E. For example in the quenching of singlet oxygen it has an antioxidant strength five hundred times stronger than Vitamin E.
Unlike many other antioxidants it has the ability of crossing the blood-brain barrier and enter into the eyes, brain and central nervous system (CNS). Most diseases of the CNS and eye are caused by increased generation of free radicals or by a decrease in the ability to remove free radicals from the body. Some of the diseases that are caused by problems with inflammation and oxidation include Glaucoma, Cataracts, and Huntington’s disease. These can be prevented by taking astaxanthin.
It has anti-inflammatory properties that are related to its strong antioxidants properties. It suppresses some of the inflammatory mediators such as, prostaglandin E-2 (PGE-2), tumor necrosis factor –alpha (TNF-a), and nitric oxide. Unlike other anti-inflammatory drugs like acetaminophen that can damage the liver and aspirin that may cause stomach bleeding, astaxanthin doesn’t have any side effects.
In people suffering from rheumatoid arthritis and carpal tunnel syndrome it has the ability of reducing pain. Studies have shown that it is able to reduce pain in rheumatoid arthritis by 40% after 8 weeks of continuous use.
It prevents Ultra Violet induces oxidative stress of the skin and prevents the photo aging of the skin. It prevents UV induced formation of wrinkles and collagen degradation in the skin. It may be applied on the skin or taken orally.
In people participating in sports it eliminates the soreness of joints after exercise, and reduces the pain caused by inflammation. This enables athletes to train harder and as a result increase their endurance, skill, and strength. This is through its ant-inflammatory and ant-oxidant effects in the mitochondria (energy producing organelle).
It strengthens the immune system, research by scientists has shown that it causes increase in production of T cells, stimulates the proliferation of lymphocytes, amplify the cytotoxicity of natural killer cells, decrease damage of DNA, and increases significantly delayed type hypersensitivity syndrome.
It prevents heart disease and reduces the risk of people already suffering from heart disease form getting a stroke or heart attack. It improves the blood lipid profiles by increasing HDL (high density lipoprotein) and decreasing LDL (low density lipoprotein).
The liver main function of the liver and kidney is the detoxification and removal of harmful substances in the body. These activities lead to the formation of free radicals. Astaxanthin being a strong antioxidant helps by destroying these free radicals hence it eliminates their oxidative effects.
As a result of its immune benefits Astaxanthin also has anti-tumor properties and as a result it prevents the development of cancer. Its prevention of cancer is also caused by its antioxidant properties and by it regulating gene expression.
Facts about Astaxanthin

Author: Darrell Miller
Subject: Facts about Astaxanthin
Astaxanthin is said to be a carotenoid which belongs to larger class of phytochemicals which is known as terpenes. It is built up of five carbon precursors. It is a metabolite of canthaxanthin and zeazanthin which contains both ketone and hydroxyl fuctional groups. Astaxanthin is a lipid-soluble pigment and is colorful. The color of it is due to the extended chain of conjugated double bonds which is also responsible for the astaxanthin’s antioxidant function. It is found in feathers of some birds, yeast, trout, shrimp, crustaceans, crayfish, krill, salmon and micro algae. The red color of cooked shellfish and red color of salmon is due to the presence of astaxanthin.
How Astaxanthin Helps the Eyes?
When astaxanthin is combined with omega-3 fatty acids and Vitamin E then it helps the eyes to recover the watery condition and it lubricates it too. It helps the eyes to absorb Vitamin E by which it then nurtures and feeds the choroid and optical nerve which is behind the retina. This is the place where the blood vessel enters in to and leaves and this is the place where communication between retina and brain are established. The macula is protected by astaxanthin by its antioxidant activity and it also helps in eliminating the free radicals. It helps in reducing the risk of cataracts and AMD. It also helps in preventing the eyestrain and it also decreases its effects. The inflammation in the muscles of the eyes is decreased by it and it also improves the blood flow of the eyes.
Health Benefits of Astaxanthin
It is considered as a strongest natural antioxidant which crosses the brain-blood barrier and protects the nervous system and brain, works in every part of skin, organs and body, crosses the retinal-blood barrier and thus protect the eyes and it reaches inside and out of every part of the cell. It also helps in repairing the injured tissue.

Subject: DHA Food Sources?
DHA, or Docosahexaenoic acid, plays an important role in the structure of the retina, cerebral cortex, sperm, and testicles. When levels of this substance decline, it has negative effects on cognitive function. Low levels are also suspect in the onset of Alzheimer's disease.
The best ways to get this omega-3 fatty acid are from natural sources. Babies can get their needs taken care of through breast milk and enriched formula. Adults need to find food sources for their needs.
Food Sources Of DHA
Cold-water varieties of fish are often excellent sources. These include salmon, bluefin tuna, albacore tuna, swordfish, anchovies, herring, sardines, caviar, and fish roe. Other types of seafood are also good sources for DHA, including crab, shrimp, lobster, clams, mussel, octopus, and scallops. Eggs and some organ meats are other sources for this essential fatty acid. For most vegetarians, eating seafood is not an option. An alternative vegetarian source is algae and seaweed. Supplements are another way to get DHA when fish, seafood, seaweed, and algae are not an option.

Subject: What Makes Neptune Krill Oil So Good For Your Health?
Neptune Krill Oil
Neptune Krill Oil is a dietary supplement that is made from the a species of Krill, a small crustacean that is quite similar to a shrimp. Neptune krill oil is rich in omega-3 fatty acids. These krills are supposed to be the largest biomass in the world and are found in the Antartic and North Pacific Oceans. While these shrimp like creatures are small in size, there is an estimate of 500mn tons of krill in the ocean. Neptune Technology has the patent for krill oil extraction and hence the krill oil that is found as supplement comes from Neptune Technologies only. As Krill form important part of the food chain, especially in the Antartic region, there have been many krill farms being setup for harvesting of krill.
Krill oil has many health benefits and is used as a dietary supplement as it contains important nutrients like omega-3 fatty acids similar to those found in fish oil, omega-3 fatty acids conjugated to phospholipids and astaxanthin. Lets us see what benefits of Neptune krill oil are:
Blood Sugar and Hyperlipidemia: Recent studies have shown the beneficial effects of krill oil in lowering blood sugar levels and totalcholesterol. Neptune Krill oil helps in lowering bad cholesterol (LDL), blood sugar, triglycerides and total cholesterol:HDL ratio. Hence it keeps your heart healthy and fit.
Premenstrual Syndrome: Neptune Krill oil is an effective and natural way to manage the symptoms of premenstrual syndrome. It not just gives relief from the physical symptoms such as bloating, breast tenderness and fatigue, but also helps in controlling the emotional symptoms (irritability, stress and depression) experienced by many women during their menses.
Inflammation relief: Studies have indicated that daily intake of krill oil helps in improving the joint health and thus helps in reducing inflammation and pain of arthritis.
Reduces risk of Cancer: Omega-3 fatty acids have anti-carcinogenic properties. Consumption of Neptune krill oil could reduce the risk of cancer. Studies have even shown that krill oil helps slowing down the growth of cancerous tumors.
Fish oil versus Krill oil: Which one is better?
Fish oil vs Krill oil is the most common debate that is becoming popular among health enthusiasts. This is because both Fish oil and Krill oil are the daily nutritious supplements that are loaded with potential health benefits. In essence, both of these oils share same characteristics in terms of their composition and their properties but still the comparisons between these two healthy oils continue. Let us discuss the pros and cons of fish oil vs krill oil and compare different parameters to decide it by ourselves, which one is better?
1. Krill oil contains higher amounts of anti-oxidants (astaxanthin) that are quite beneficial for health while many manufacturers add anti-oxidants from outside in fish oil.
2. Both the oils are rich source of omega 3 fatty acids, but fish oil contains high concentration of harmful metals that can cause unwanted side-effects if consumed.
3. Fish oil is made commercially from farm raised fish, which lacks useful nutrients, whereas krill oil is made from the pristine waters of Antarctica.
Krill oil is nature's rich source of important nutrients. Neptune krill oil is a vital supplement that has many health benefits.

Many natural health practitioners are looking at chitin as a possible weight-loss tool in a diet program. While still under study, proponents of it have helped this natural product and formulations made from it popular. Those seeking to lose weight efficiently are buying this product in droves. Manufacturers and marketers of chitin have seen great sales growth in Japan and the United States in recent years.
Chitin is a positively charged polysaccharide that comes from an animal source. This source is shellfish in the form of shrimp, crab and lobster. A polysaccharide is a string of sugar molecules found in the outer shell of these crustaceans. Chitin is also found in marine coral and the outer shells of certain insects, such as beetles and ants. Chitin shares chemical similarities with cellulose and starch, which are plant fibers.
The weight-loss benefits of chitin are in its binding properties. Some researchers believe that the positively charged polysaccharides attract negatively charged bile acids and free fatty acids. These acids are now bound by the positively charged chitin and therefore are not absorbed into a person's system. The result is the prevention of an increase in dietary fat, which puts the pounds on a person's frame.
Some evidence from studies does suggest that chitin breaks down in the stomach and changes to a gel. Some researchers believe this is where the binding takes place as this gel traps fats and cholesterols. This process is believed to occur in the intestine, where chitin prevents the fat from becoming absorbed and digested.
All types of fiber are beneficial for preventing the absorption of fat into the body, at least to some degree. Studies show that chitin, as an amino polysaccharide fiber may do this to a greater degree. Some proponents believe chitin has the capacity to expel up to four times its weight in fat. Some claim it binds 10 times its weight in fat and does this better than any other kind of fiber.
Some believe chitin works best when used in conjunction with a high-fat meal. If it's going to be one of those high-fat intake days, they say taking chitin can help you counter the fat. Taking chitin may help bind the fat molecules and take them through your system until they're eliminated. However, chitin does not bind carbohydrates, protein, or alcohol. Over-indulgence in them, even with chitin added to your diet, may mean you will still put on weight.
Because chitin is a non-digestible, non-absorbable fiber, it acts as a carrier. It doesn't absorb into your body as other foods can. It helps carry harmful fats away through its binding capabilities before they have a chance to settle in. Studies suggest chitin may do this and help improve blood cholesterol levels as it goes about its work.
Chitin is a calorie-free fiber supplement. A product that is abundantly available, it is even used in food manufacturing as an edible film to protect foods from spoiling. It is often found at a reasonable cost and is a product known for having few side effects. One caveat with chitin is that those allergic to shellfish should not consume chitin. In addition, pregnant women should not take chitin products because of a possible reduction in calcium and vitamin D absorption. Of course, any weight-loss program needs to rely on healthy foods and exercise in addition to any weight-loss supplements. It's all part of an overall healthy approach to losing weight.
Along with its possible benefits as a weight-loss tool chitin has other benefits. It is used in the manufacture of surgical thread. Being biodegradable, it dissolves over time as a wound heals. It also has properties that allow for its use as a wound-healing agent.
Studies continue in the uses of chitin as a weight-loss product. As a natural product, readily available, diet supplement manufacturers strive to make innovative products from it. Their focus is to further research chitin so they can use it to help those striving to take control of their weight.

Astaxanthin, a Member of the Carotenoid Family, is a Powerful Antioxidant
January 31, 2008 09:00 AM
Author: Darrell Miller
Subject: Astaxanthin, a Member of the Carotenoid Family, is a Powerful Antioxidant
Astaxanthin is a member of the carotenoid family responsible for the red color of many types of algae. Being a carotenoid, it is a powerful antioxidant and free radical scavenger as well as support proper eye function.
However, such a bland statement belies the true worth of astaxanthin in its fight against free radicals. It is of particular benefit in its ability to absorb the high energy of singlet oxygen, releasing it as heat, and returning the singlet oxygen to its ground neutralized state. Singlet oxygen is a particularly harmful and reactive oxygen species of free radical that is formed in the body as part of our normal metabolism, and that contains a high level of free energy that can be used to oxidize and destroy the cells of your body.
In achieving this, astaxanthin is regarded as one of the most potent plant derived antioxidants known, being up to ten times more active than beta carotene, Lutein or its cousin canthaxanthin. So why are antioxidants so valuable to our biochemistry and what would happen if they did not exist?
Free radicals are thieves that use your body as their operating ground. They operate by stealing an electron from a molecule that comprises part of you, and in some cases when this occurs the cell from which the electron is removed is destroyed. Generally electrons go around in pairs, but occasionally an electron pair can lose one of the electrons during a chemical reaction. Many such reactions occur naturally inside the body, especially during the production of energy from blood sugars in the mitochondria, and such a molecule containing a single unpaired electron is called a free radical. Free radicals are also generated by the reactive components of many pollutants such as traffic fumes and cigarette smoke, tars and pesticides, and also by the effect of UV radiation in sunlight.
The only purpose of a free radical is to steal an electron from the first source it can find. Such reactions occur very rapidly after the free radical has been generated, and if this electron belongs to another body cell, then the cell is destroyed leading to effects such as premature aging or even cancers. Free radical oxidation of the LDL lipids that carry cholesterol around the blood causes the deposition of fatty plaques inside arterial walls that eventually become constricted or even blocked, leading to heart disease or strokes.
That is why antioxidants that destroy these free radicals are so prized, and the more of them that there are in your body then the less affect the free radicals will have on you. You will retain your youthful looks longer, and will be less liable to suffer from heart disease, cancers, circulation problems and conditions such as diabetes. Many abnormal conditions can be laid at the door of free radicals.
The stronger the free radical, the more harm it can do to you and a strong antioxidant such as astaxanthin is a very powerful weapon in your armory against them. Astaxanthin is a member of the oxygenated xanthophylls, and its high level of antioxidant power likely comes from the ketonic and hydroxyl functional groups of the ionone ring structure. It is more polar than most carotenoids, and this is a likely reason for its ability to span the cell membrane layers, with the active groups close to the hydrophilic-hydrophobic interface. They are thus more readily available at the sites where most free radicals tend to be found and provide immediate protection to the cell membrane and also to the intracellular mitochondrial membrane.
Many antioxidants destroy free radicals by donating an electron, and become oxidized themselves. Astaxanthin, however, does not do this, but instead adds the free radicals to its long double bonded chain hence avoiding oxidation and rendering it much more powerful than normal antioxidants. It is unusual among antioxidants in that it is also able to cross the blood-brain barrier, and so reduces oxidative stress that can cause neurological disorders in general, and also problems with eyesight. It can also attach itself to lipoproteins to enable it to be carried throughout the bloodstream, being available anywhere that free radicals are generated. The carotenoid is also active against active oxygen species that are responsible for inflammation.
Another property is its ability to neutralize the oxygenated free radicals formed by the photo-oxidation properties of UVA and UVB radiation. Included in these are the previously mentioned highly reactive singlet oxygen and also triplet oxygen that astaxanthin is able to neutralize without becoming oxidized. In fact reactive oxygen species in general can cause oxidative stress, and they have been thought responsible for many forms of disease and health conditions, and the powerful effect of astaxanthin in targeting many of these has led it to be regarded as highly beneficial to the immune system and to health in general.
Another benefit is the ability of the substance to help prevent the oxidation of high density lipoproteins (HDL) that are responsible for carrying cholesterol in the blood back to the liver for destruction. Free radical oxidation of HDL impairs its ability to transport cholesterol, and so decreasing the level of such free radical oxidation will by definition increase the quantity of good HDL available, and hence reduce the concentration of cholesterol in the blood. Studies have proved this to be the case, and astaxanthin supplements are very beneficial to those suffering from high blood cholesterol levels, and helps protect them from heart disease and strokes.
The substance is naturally available from a wide range of marine sources, such as lobsters (where it was first discovered), shrimp, salmon, trout and in a wide variety of red and green algae. The substance is also used as a red pigment. Carotenoids are essential, meaning that they are not produced in the human body and can only be obtained in our diets.
For that reason, the most convenient way to take it, apart from continually eating shrimp and lobster, is as a supplement. Astaxanthin is available either as a powerful antioxidant in its own right, or in combination with other substances with which it acts to provide a very strong deterrent to any free radicals that think they can freely roam your body.

Carotenoids are a class of lipid-soluble natural pigments found in plants, as well as in phytoplankton and certain fungi and bacteria. The red, orange and yellow colors seen in fruits and vegetables are from carotenoids. When various aquatic animals such as salmon and shrimp eat plants containing some of the over 700 compounds that make up the carotenoid class, those animals are also decorated with the same brilliant colors. However, carotenoids do more than provide color - they’re powerful phytonutrient antioxidants. Beta carotene, lutein, and lycopene are some of the more well-known carotenoids, but the most powerful found to date is astaxanthin.
Astaxanthin is a fat-soluble carotenoid with a unique molecular structure that makes it an extremely effective antioxidant. The PDR® Medical Dictionary 2nd Edition defines an antioxidant as, “An agent that inhibits oxidation; any of numerous chemical substances, including certain natural body products and nutrients, that can neutralize the oxidant effect of free radicals and other substances.” Not only is astaxanthin a potent free radical scavenger, but it also can protect against oxidation, which limits the number of free radicals produced. Additionally, it’s very effective at quenching a molecule called singlet oxygen, a harmful reactive oxygen species formed through normal biological processes. Singlet oxygen possesses a high amount of excess energy that must be released to keep it from damaging other cells. Astaxanthin absorbs this energy and dissipates it as heat, and in the process returns the singlet oxygen to a grounded state.
A growing body of research is showing that astaxanthin is the creme de la creme of phytonutrient antioxidants. Studies comparing astaxanthin to other carotenoids have shown it to possess antioxidant activity up to 10 times stronger than that of beta carotene, canthaxanthin, lutein and zeaxanthin.4 A study published in 1990 conducted by Kurashige and associates compared the effectiveness of vitamin E and astaxanthin for the prevention of lipid peroxidation. The results showed that astaxanthin is 100-500 times more effective in preventing lipid peroxidation in vivo than vitamin E.5
Astaxanthin in algae provides protection against the effects of ultraviolet (UV) light exposure, and studies are showing that this protective effect is also imparted with dietary astaxanthin. Scientists believe that astaxanthin effectively scavenges the oxygen radicals produced through photo-oxidation caused by UV exposure. A 1995 study by Savoure and associates studied the protective effects of astaxanthin, beta carotene and retinol against UVinduced photo-oxidative stress. The results showed that astaxanthin is extremely effective in preventing increases of certain polyamines created through photo-oxidation, which damages skin. A particular polyamine was found to increase only 1.5-fold in subjects fed astaxanthin, whereas subjects in the control group experienced a significant 4.1- fold increase. It was concluded that astaxanthin works through a particular enzyme, increasing this enzyme’s consumption of polyamines in response to irradiation.
Research has shown that astaxanthin also offers cardioprotective effects through its ability to decrease oxidation of HDL (“good” cholesterol), which is a cholesterol transporter in the blood. It‘s well established that high levels of HDL and low levels of LDL (“bad” cholesterol) are desirable for healthy cardiovascular function, so protecting HDL from oxidation means there’s more circulating in the bloodstream. In a 1992 study by Murillo, subjects were fed dietary astaxanthin for 30 days. HDL cholesterol increased 57mg/dL, compared to the control diet (42.4 mg/dL). LDL cholesterol decreased from 12.5 mg/dL to 9.6 mg/dL. Clearly, astaxanthin exhibited an influence on the ratio of these two lipoproteins.
We can thank the lobster for the discovery of astaxanthin. Researchers working with an extract of the lobster Homarus astacus first characterized astaxanthin in 1938. It was soon discovered that astaxanthin is abundant in nature, although mostly in very low concentrations. The greatest source found is in green algae called Haematococcus pluvialis, which also contains other carotenoids such as beta carotene and lutein. NOW® Foods Astaxanthin supplies 4mg of this effective phytonutrient antioxidant and is an excellent source of this outstanding member of the carotenoid family. The astaxanthin used for our product is BioAstin® supplied by the Cyanotech Corporation, one of the premier suppliers of highquality astaxanthin taken from Haematococcus pluvialis, the richest natural source discovered. In addition to Astaxanthin, NOW® offers other carotenoids, including Lutein, Beta Carotene and Lycopene. Research continues to support the inclusion of carotenoids in the diet to support overall health. This is even truer for those with less than perfect diets and for those who smoke or spend any time with someone who does.

Pregnant and eating for two...

Subject: Pregnant and eating for two...
Not - Quite - Dual - Nutrition
It’s time to ditch a dietary cliché often foisted on expectant moms. “try to keep in mind that you are not eating for two, you are carefully eating for one,” write Catherine Jones and prenatal nutrition expert Rose Ann Hudson in Eating for Pregnancy (Marlowe & Company), who add that pregnancy “is not a time to skip meal, eat junk food or lad up on empty calories for quick energy.” The idea is to eat a nutritious diet that allows you to gain weight gradually as your baby grows.
It helps to be at a healthy weight when starting a family. Being overweight makes conception more difficult, and at least one study ahs found a link between excess maternal weight and the risk of a birth defect called cleft palate (in which the roof of the mouth is split from behind the teeth to the nasal cavity). However, dieting during pregnancy may actually program a child for obesity by rewiring the developing brain, so try to lose weight before you try to conceive.
How much should you expect to gain over the course of nine months? “A lot depends on your unique circumstances and the advice of your health care provider, but in general you can anticipate adding from two to five pounds a month for the first 14 weeks and roughly a pound a week thereafter until your due date-between 25 and 35 pounds in total. That translates into roughly and extra 300 calories a day; Jones and Hudson say that more nourishment may be necessary if you are breastfeeding, extremely active or carrying more than one child. Since stress and anxiety often lead to out-of-control eating (and gaining), be sure to tend to your own emotional needs during what can be a very exhilarating, yet sometimes overwhelming, time of life.
For maximum nutrition try to eat a variety of foods while avoiding anything that provokes morning sickness. Whole grains provide both steady energy (unlike sugar-fueled spikes and crashes) and B vitamins to boot. Do not scrimp on fat-your baby’s developing nervous system depends on it-but “don’t use your pregnancy as an excuse to pig out, either,” warn Jones and Hudson. Stick with such unsaturated fats as olive oil along with rich sources of omega-3 fatty acids like flax seed oil. You definitely want to indulge in those omega-3s, which appear to boost infant intellectual development. Fish is a fine source of both omega-3 and the high-quality protein needed to build your baby’s tissues, but beware: Some species such as fresh tuna, swordfish, tilefish and king mackerel, can be contaminated with mercury. Your best low-mercury bets are catfish, pollock, salmon, and shrimp. (Other good protein sources include chicken, cottage cheese, lean red meat, yogurt and milk, all organically sourced whenever possible.)
Supplemental fish oil is another omega-3 possibility because “mercury is found in the muscle of fish and not in the oil,” according to OSU’s Jane Higdon, who suggests consulting your health care practitioner for advice. “If I was going to take a fish oil supplement, I’d look for one that the manufacturer is testing for PCBs (an industrial pollutant),” such as products that meet California’s Proposition 65 standards.
Don’t forget to stock the fridge with fresh produce. Fruits and veggies are richly endowed with vitamins and minerals; for example, making like Popeye and downing your spinach helps ensure you get plenty of folic acid and iron.
These superfoods also supply phytonutrients, substances that may actually help protect your baby against cancer even as they enhance your own well-being. Studies on the link between maternal diet and childhood cancer protection are in the early stages according to Dr. David Williams, a researcher at the Linus Pauling Institute, but he says that shouldn’t stop you from loading up on cancer-fighting green stuff. “Certainly among the vegetables the cruciferous ones (the broccoli family) are particularly valuable in protecting against cancer,” he says. “These vegetables are also a good source of fiber and vitamin C.”

Cuddlin’ in the Kitchen
You and your sweetie can turn up the heat by cooking together.
Since the beginning of time, the pleasures of the table have been intertwined with those of the boudoir. (Remember the scene in the film Tom Jomes in which Tom and his amorata-of-the-moment wolf down a meal while staring lustily into each other’s eyes?) But when most of your kitchen time is spent trying to get everyone fed and out of the house in time for the night’s soccer game/ PTA meeting/ballet lesson, it can be tough keeping the pilot light lit on your love.
That’s why one of the best ways to spice up your sex life is to prepare a sensuous meal together sans offspring (thank heavens for doting grandparents with spare rooms!). A little fourhanded cooking- preferably while sharing some suggestive banter- can create chemistry that allows your playful, non-parenting side s to emerge, enhancing intimacy and setting the stage for the seductive feast to follow.
Just as the frenzied pace of modern living can often foster a sense of separation, cooking together as a couple can promote a sense of union. “Eventually you get a feel for your partner’s rhythms and adjust yours accordingly,” says food TV personality Jacqui Malouf, author of Booty Food (Bloomsbury). “Before you know it you’re passing the coriander, peeling the potatoes and stirring the risotto at precisely the right moments.”
With time, you can learn what each of you does best: Who has a flair for combining spices in just the right proportions? Who can chop carrots into perfect little matchsticks without taking all night? Since nothing kills the mood more than arguing over who misplaced the baker’s chocolate or the pasta platter, buy your ingredients earlier in the day and have all the necessary utensils out and at the ready. (Safety note: while two in a tiny kitchen can be steamily cozy, do be careful with hot pots and sharp knives.)
Four hands can also be better than two, so why not make the most of it? Malouf suggests approaching your combined efforts with a sense of adventure: “Use more than three ingredients in a salad dressing! Be daring with your desserts! Try concocting something with squab or squid or quince or quail- the sky’s the limit.”
One advantage of using exotic ingredients (or at least foods not normally found on your weekly shopping list) is that they can help you and your partner break through the limits of everyday experience by reawakening long-dormant senses. Go ahead- run your fingertips over the rough rind of a pomegranate before feeling the smooth, full seeds within. Inhale the sweet, perfumed scent of a dead-ripe apricot, and appreciate its downy skin. Admire the cool green beauty of a cut avocado, and share a spoonful with your sweetie.
Avocado, in fact, is one of the foods known for inflaming passion based on its suggestive shape, along with artichoke and asparagus- and that’s just the AS! (Chocoholics rejoice: Chocolate, full of the same feel-good chemical released by the brain when one falls in love, also makes the ecstasy encouraging grade, even when obtained in standard shapes.) “coincidentally, many foods long considered aphrodisiacs are low in fat (avocado and chocolate are delectably healthy exceptions) and are high in vitamins and minerals,” write Martha Hopkins and Randall Lockridge in Intercourses: An Aphrodisiac Cookbook (Terrace Publishing). “A diet heavy in these foods, then, yields a healthy blood healthy body with the energy, blood flow and nutrients needed for a peak sexual experience.” (The way these foods feed the imagination- the ultimate smorgasbord of pleasure- is a bountiful bonus.) Other foods, such as honey, have been treasured for supplying the energy needed to fan love’s flames far into the night; no wonder the sweet, sticky stuff shows up in a number of naughty-night concoctions.
Just as Venus, the Roman goddess of love, emerged fully formed from the sea, so do the foods that best encourage those under her spell. In addition to being chockfull of healthy protein, “seafood is elegant, clean and light enough to keep your sleek loving machine fully fueled but never weighed down,” says Jacqui Malouf. Oysters are famous- or infamous- for their amorous effects (Cassanova was fond of them) but aren’t for everyone; other romantic dining favorites include shrimp or scallops.
Time to Eat
Once you’ve worked your kitchen magic together, it’s time to move the action into the dining room. Again, a little preparation can keep the evening at a slow, sensuous boil. Use the best china you have, along with matching silverware, cloth napkins and nice glasses (sippy cups don’t count). The warm glow of candlelight can both set off your tantalizing table and set your hearts aflame, along with a rose or two in the most decorative vase you own. Music (from Mozart to Motown, depending on your taste) is another surefire mojo mover. But please guys- catch up with CNN or ESPN some other time.
When you do finally sit down to dinner don’t rush, even (especially) if fast-forward eating is the norm in your house. “Treat the food as if you are making love for the first time,” advises Kerry McCloskey in The Ultimate Sex Diet (True Courage Press). “Before putting any in your mouth, inhale its aroma to get your digestive juices flowing…Cut your food into small, bite-sized pieces, (which) will ensure that you enjoy each bite.” The idea is to enhance all of your senses, which will come in handy later on in the evening.
You can make your couple dining experience even more intimate by feeding each other; some foods. Like asparagus spears and shrimp, beg for finger-feeding. McCloskey recommends also trying chopsticks: “Because it will take longer to maneuver your food when using them, you will feel full sooner with less food.” That’s important since you don’t want to overeat- passing out right after dessert is not the way to impress your partner (they’ve seen you snoring away on the couch a hundred times before).
In the wee hours, happily exhausted, you can ponder this: No matter how hectic your lives get, you should always make time for each other. You already share a mortgage and kids. Cooking together is a great way to share sensuality, too.
CHITOSAN: The Fiber that Binds Fat

Subject: CHITOSAN: The Fiber that Binds Fat
Chitosan is a natural product that inhibits fat absorption. It has the potential to revolutionize the process of losing weight and by so doing, reduce the incidence of some of the most devastating Western diseases we face today. Chitosan is indigestable and non-absorbable. Fats bound to chitosan become nonabsorbable thereby negating their caloric value. Chitosan-bound fat leaves the intestinal tract having never entered the bloodstream. Chitosan is remarkable in that it has the abilty to absorb an average of 4 to 5 times its weight in fat.60
The same features that allow chitosan to bind fats endow it with many other valuable properties that work to promote health and prevent disease. Chitosan is a remarkable substance whose time has come.
Chitosan: A Brief History
Chitin, the precursor to Chitosan, was first discovered in mushrooms by the French professor Henri Braconnot in 1811.61 In the 1820’s chitin was also isolated from insects.62 Chitin is an extremely long chain of N-acetyl-D-glucoseamine

b) Abbreviated Chitosan structure
c) Fanciful "crab oligomer" Chitosan structure showing functional claw
glucoseamine units. Chitin is the most abundant natural fiber next to cellulose and is similar to cellulose in many respects. The most abundant source of chitin is in the shells of shellfish such as crab and shrimp. The worldwide shellfish harvest is estimated to be able to supply 50,000 tons of chitin annually.63 The harvest in the United States alone could produce over 15,000 tons of chitin each year.64
Chitin has a wide range of uses but that is the subject of another book. Chitosan was discovered in 1859 by Professor C. Rouget.65 It is made by cooking chitin in alkali, much like the process for making natural soaps. After it
• Waste Water Purification • Stabilizing Oil Spills • Stabilizing Fats in Food Preparation • Antibacterial Protection for Seeds • Flavor Stabilizer • Stabilizes Perishable Fruits/Vegetables • Ion Exchange Media • Bacterial Immobilizer • Cosmetic and Shampoo Additive • Tableting Excipient • Absorbant for Heavy Metal Removal
Table 5. Industrial Uses of Chitosan 66-75
• Absorbs and Binds Fat • Promotes Weight Loss • Reduces LDL Cholesterol • Boosts HDL Cholesterol • Promotes Wound Healing • Antibacterial/Anticandida/Antiviral • Acts as Antacid • Inhibits the Formation of Plaque/Tooth Decay • Helps Control Blood Pressure • Helps Dental Restoration/Recovery • Helps to Speed Bone Repair • Improves Calcium Absorption • Reduces Levels of Uric Acid
Table 6. Health and Nutrition Uses of Chitosan 60,66,77-107
is cooked the links of the chitosan chain are made up of glucosamine units. Each glucosamine unit contains a free amino group. These groups can take on a positive charge which gives chitosan its amazing properties. The stucture of chitosan is represented schematically in Figure 2. Research on the uses of chitin and Chitosan flourished in the 1930s and early 1940s but the rise of synthetic fibers, like the rise of synthetic medicines, overshadowed the interest in natural products. Interest in natural products, including chitin and chitosan, gained a resurgence in the 1970s and has continued to expand ever since. Uses of Chit osan Some of Chitosan's major uses—both Industrial and Health and Nutritional—are listed in Tables 5 and 6.
Chitosan has been used for about three decades in water purification processes. 67 When chitosan is spread over oil spills it holds the oil mass together making it easier to clean up the spill. Water purification plants throughout the world use chitosan to remove oils, grease, heavy metals, and fine particulate matter that cause turbidity in waste water streams.
Fat Binding/ Weight Loss
Like some plant fibers, chitosan is not digestible; therefore it has no caloric value. No matter how much chitosan you ingest, its calorie count remains at
Dietary Fiber % Fat Excreted Dietary Fiber %Fat Excreted Chitosan 50.8 + 21.6 Carrageen 9.6 + 1.9 Kapok 8.3 + 1.1 Sodium Alginate 8.1 + 2.2 Pectin 7.4 + 1.9 Locust Bean 6.0 + 1.8 Guar 6.0 + 1.7 Konjak 5.2 + 0.6 Cellulose 5.1 + 2.1 Karaya 4.9 + 1.5 Acacia 4.6 + 0.9 Furcellaran 4.4 + 0.9 Chitin 4.3 + 1.0 Agar 2.8 + 0.4
TABLE 7. Effects of Dietary Fibers on Fecal Lipid Excretion 109,110
fibers, chitosan’s unique properties give it the ability to significantly bind fat, acting like a “fat sponge” in the digestive tract. Table 7 shows a comparison of chitosan and other natural fibers and their ability to inhibit fat absorption. Under optimal conditions, Chitosan can bind an average of 4 to 5 times its weight with all the lipid aggregates tested.60 (NOTE: This assessment was made without the addition of ascorbic acid which potentiates this action even further.77 Studies in Helsinki have shown that individuals taking chitosan lost an average of 8 percent of their body weight in a 4-week period.76 Chitosan has increased oil-holding capacity over other fibers.108 Among the abundant natural fibers, chitosan is unique. This uniqueness is a result of chitosan’s amino groups which make it an acid absorbing (basic) fiber. Most natural fibers are neutral or acidic. Table 7 summarizes the in vivo effects in animals of various fibers on fecal lipid excretion. As can be seen from the results listed, ingestion of chitosan resulted in 5-10 times more fat excretion than any other fiber tested. D-Glucosamine, the building block of chitosan, is not able to increase fecal fat excretion. This is due to the fact that glucosamine is about 97 percent absorbed while chitosan is nonabsorbable. Fats bound to glucosamine would likely be readily absorbed along with the glucosamine. Chitosan, on the other hand, is not absorbed and therefore fats bound to chitosan can not be absorbed.
Chitosan has the very unique ability to lower LDL cholesterol (the bad kind) while boosting HDL cholesterol (the good kind).78 Laboratory tests performed on rats showed that “chitosan depresses serum and liver cholesterol levels in cholesterol- fed rats without affecting performance, organ weight or the nature of the feces.”79 Japanese researchers have concluded that Chitosan “appears to be an effective hypocholesterolemic agent.”80 In other words, it can effectively lower blood serum cholesterol levels with no apparent side effects. A study reported in the American Journal of Clinical Nutrition found that Chitosan is as effective in mammals as cholestryramine (a cholesterol lowering drug) in controlling blood serum cholesterol without the deleterious side effects typical of cholestryramine. 81 Chitosan decreased blood cholesterol levels by 66.2 percent.82 It effectively lowered cholesterol absorption more than guar gum or cellulose.83 Laboratory test results indicated that a 7.5% chitosan formula maintained adequate cholesterol levels in rats, despite a dramatic increase in the intake of cholesterol. 84

Neptune Krill Oil
Essential fatty acids are enormously important to your health. They are the building blocks for phospholipids, and phospholipids are the building blocks for your cell membranes – the protective layer and gatekeeper of your cells. A good essential fatty acid balance provides building blocks for healthy cells, but an imbalance can lead to critical health concerns. Source Naturals introduces NKO™ Neptune Krill Oil, the first product featuring phospholipids specially integrated with omega-3 essential fatty acids for building healthy cell membranes. It also includes antioxidant protection. In human studies, NKO supplementation supported healthy joints, the heart, lipid and blood sugar levels, energy production, athletic performance and liver function, and eased women’s PMS symptoms.
Support Your Protective Cell Membranes
Source Naturals brings you the science of natural NKO™ Neptune Krill Oil, the only product to boast significant healthinducing potencies from three different important nutritional categories: omega- 3 fatty acids, phospholipids and antioxidants. These three nutrients work together to support healthy cell membranes, joints, the heart and many other body systems. And NKO eases PMS symptoms for women.
Multiple Benefits of Krill
NKO™ Neptune Krill Oil has many benefits. Unlike fish oil products, NKO doesn’t contain dangerous levels of mercury or lead, doesn’t go rancid quickly and has a clean, fresh taste. Made from hearty krill, shrimp-like crustaceans that thrive in the harsh Antarctic waters, it is the only product to contain phospholipids specially integrated with omega-3 essential fatty acids. This unique structure provides important cell membrane building blocks in the ratios used by the body and may be far better utilized than stand-alone phospholipid or omega- 3 products. The result: stronger cell membranes that function better to maintain your health. The desirable composition of NKO, high in omega-3 essential fatty acids, also provides a healthy balance. High levels of omega-6 fatty acids, such as from processed foods, enable your cell membranes to initiate over-production of certain prostaglandins that can lead to cellular irritation, heart system imbalances and other concerns. But omega-3 fatty acids can reverse that trend. Omega-3 fatty acids such as DHA and EPA (docosahexaenoic and eicosapentaenoic acids) compete with arachidonic acid for building blocks, such as the COX-2 enzyme, and can instead lead to balanced levels of the many different types of prostaglandins. The result: cellular comfort, heart health and many other healthy body systems. NKO also contains natural antioxidants, which are cell membrane protectors. Each serving contains 100 IU of vitamin A and a very high level, 1.5 mg, of astaxanthin, an immune-supporting carotenoid, which can be used to guard your cell membranes from free radical damage. And NKO 100% pure krill oil is manufactured by Neptune Technologies & Bioresources Inc. in adherence to all environmental harvesting standards. Source Naturals is pleased to partner with your local health food store to bring you NKO™ Neptune Krill Oil. Try this unique, potent and comprehensive product for your better health today.
