Take this happy pill: Deficiency in vitamin D is linked todepression among urban Malaysian women
March 25, 2019 05:48 PM
Vitamin deficiencies are running rampant around the world, impacting a substantial amount of individuals. Over 70% of Malaysian women in urban areas tested positive for a vitamin D deficiency, specifically. The reason so many Malaysian women are prone to vitamin D deficiencies is because they have darker pigmentation, and they are heavily restricted in many forms of clothing. The lack of sunlight exposure due to these characteristics is what potentially contributes to an increase in levels of depression.
"Based on the study findings, over 70 percent of the urban Malaysian women surveyed were vitamin D deficient."

Kelp is the common name given to many species. Kelp is often known as seaweed or sea kelp rich in vitamins, minerals and especially in iodine. It also contains potassium, iron and magnesium. The seaweed appears in brown color because of the presence of yellow-brown PIGMENTATION and grows at a rapid speed beneath the ocean. Seaweed grows up to 1500 ft long which is the largest and longest among all the sea plants. Many people are using Kelp as natural iodine supplement to help thyroid functions.
The medicinal benefits of kelp are uncountable.
Such benefits include:
Kelp for thyroid
Kelp is a very rich source of iodine which is an essential element for the easy functioning of gland thyroid and regulates thyroid hormones. The kelp or iodine rich diet benefits in the treatment of thyroid glands. The iodine helps to speed up metabolism and maintains the immune system.

Melatonin, Sleep, and insomnia
February 08, 2012 08:01 AM
The pattern according to which a human being wakes up and remains awake during the day and falls asleep at night is regulated by a hormone known as Melatonin. This hormone was first discovered by a team of researchers that was led by a Yale dermatologist by the name of Dr. Aaron Lerner. While Lerner passed away on the 3rd of February, 2007, however, his discovery was quite groundbreaking in medical science.
Initially back in 1958, the Melatonin hormone that was isolated from the pineal gland inside a frog's brain was believed to be a cure for skin PIGMENTATION problems. However, it was later discovered that rather than helping to treat skin PIGMENTATION problems, this hormone had a role in regulating the wake and sleep pattern of human beings. There, Dr. Aaron Lerner and his team of researchers came to conclusion that sleep related problems; especially insomnia could be treated using this hormone.
Almost millions of Americans these days are suffering from sleep disorders include insomnia, narcolepsy, etc. Insomnia, in particular, is not really a disease but is merely a disorder or a symptom that makes an individual sleepless and makes it difficult for them to fall asleep. In fact, people suffering from insomnia are hardly able to get any quality sleep, especially at night, which is most essential for them. Those people who have had a couple of sleepless nights can be certain that they are suffering from insomnia, however, people rarely visit a doctor when suffering from this sleep disorder.
There are a variety of reasons that cause insomnia. Anxiety, depression, discomfort, specific medical illnesses, stress, etc. are some of the most common causes of insomnia. Insomnia can last for both short and long periods of time. When it comes to safely treating insomnia, the melatonin hormone can be used for this purpose. Presently there are numerous natural melatonin supplements available in the market that can be used by insomniacs as a remedy for the sleep disorder they are suffering from.
It was somewhere during the mid 1990s when this hormone became available in the form of pills. At that time travelers who frequently suffered from jet lag used supplements containing this hormone.
These days, after further research claims are being made that many other benefits are also offered by this antioxidant hormone. Research has proven that headaches and migraines, which are among the causes of insomnia, can be effectively relieved by using supplements containing melatonin. It is believed that the certain cancers can also be prevented from further developing with the help of this hormone.
As for insomnia, it is a sleep disorder that disrupts the natural sleep and wake pattern of the body. This hormone, therefore, restores that pattern back to normal causing people to feel sleepy at the right time when they actually need sleep. This sleep is being promoted by a natural hormone so these supplements cannot be considered drugs and neither do they cause an individual to feel as if they are drugged. Insomniacs will simply begin feeling naturally sleepy and this is why it is safe to use melatonin supplements to treat insomnia.

How Does Lutein Help Fight Against Macular Degeneration?
August 19, 2011 01:11 PM
Macular degeneration is a medical condition that affects older adults in most cases which results in a loss of sight or vision just in the center of the visual field due to damage of the retina. This is a very serious condition of the eye and it progresses over the years and in case left untreated may lead to further loss of sight. It has been found to be a major cause of older adults being visually impaired and usually age range is 50 years or older. Macular degeneration makes it hard or impossible to read or recognize faces, even though enough peripheral vision remains to make daily life activities remain doable.
Lutein from the Latin meaning of yellow, luteus, is a xanthophyll and is a naturally-occurring carotenoid. It is abundant in leafy vegetables which are green in color like spinach and kale. Lutein can also be found in egg yolks and is also present in plants as a fatty-acid tester and most of all, it can be found in the retina and concentrated in the macula, which is a small area of the retina mainly responsible for central vision. This helps the eyes to be protected from oxidative stress and blue light photons with high energy.
Several studies have found that an increase in macula PIGMENTATION helps decreases the risk for eye diseases and one of them is Age-related Macular Degeneration(AMD). Some concluded that visual activity is improved with lutein supplementation alone or lutein together with other nutrients. Other studies also show that AMD seemed to be directly related to having low carotenoids in the body. It does follow in this case that increased green leafy vegetable consumption does help prevent the risk of AMD. Sufficient lutein intake indicates risk reduction for macular degeneration and this can be obtained from a proper diet, but considering that the daily focus of attention is for the lutein.
It commonly follows that this daily attention to the diet to get all the required lutein for our body is where supplementation suggestion comes in since many are not able to do so especially for people around the age group of 70 and up where the attention needed is just too taxing. And since failure to have sufficient lutein is not acceptable for these people with a high risk of AMD or those already with AMD but hopes to slow it down or even stop the progression of the decease, supplementation is a viable and reliable way to assure sufficient lutein intake. This would eventually lead to increases in blood serum levels that would be equal to a diet sufficient of high lutein foods.
However it’s worthy to note that risk reduction does not equate to a cure because once macular degeneration has started there is no way to reverse it. But reduction of risk may be an implication of prevention for some people. Further research needs to be done. However in terms of prevention before the decease starts, results have been promising.
Lycopene is More than Just a Tomato Extract!
February 08, 2011 04:38 PM
Lycopene is a naturally occurring antioxidant, and a very powerful one at that. Like beta-carotene, it is a carotenoid, a phytochemical that gives certain plants their orange or bright red PIGMENTATION. While lycopene belongs to a group of carotenoids called carotene, known precursors of vitamin A, it does not get converted into vitamin A inside the human body, which is not a bad thing, inasmuch as lycopene in itself exhibits antioxidant properties that surpass the effects of vitamins.
Tomatoes are very rich in lycopene, and indeed consumptions of tomatoes have been reported to show the antioxidant properties of lycopene. Papayas, pink guavas, and watermelons are also good sources of this compound, but the plant source identified to have the highest concentrations of lycopene is Gac, in English also known as Sweet Gourd, a bright red fruit native to Southeast Asia and largely unknown to the rest of the world. With that, a significant fraction of the total lycopene consumption worldwide is derived from tomatoes.
Reactive Oxygen Species (ROS)
Chemical reactions in the human body that respond to the presence of oxygen are part of a process called oxidation, which takes place everywhere else in nature. These reactions entail a change in the oxidation number of atoms or molecules involved in the movement of electrons between molecules inside the body, giving rise to toxic by-products collectively known as reactive oxygen species.
When cells produce the energy that they use to power their physiological functions, they also produce reactive oxygen species, or ROS, which is now believed to be a key factor in the progression of physical infirmities associated with the aging process of human beings and other mammals. That being said, ROS are actually in the employ of the immune system, and particularly effective against pathogens, which may be invasive extracellular matter or harmful microorganisms.
Every single cell make use of enzymes that change the chemical makeup of unnecessary ROS, which must always be kept in check as they damage cells even at low amounts. These enzymes outmaneuver the damaging activities of ROS, thereby protecting the cells. In spite of that, the human body is known to produce more ROS as we age or during long-standing exposure to stress.
Lycopene versus ROS
One type of ROS is singlet oxygen, a form of oxygen that is highly reactive to free radicals. In fact, singlet oxygen is a known catalyst of free radicals especially when it gets excited at the molecular level. Lycopene is the best known carotenoid to counter the damaging effects of singlet oxygen in the human body, and reported to have antioxidant properties far superior to vitamin E and glutathione.
The good thing about lycopene is that its bioavailability compounds when exposed to heat, so cooking tomatoes actually brings out the goodness of this chemical compound. Lycopene acts against the proliferation of cancer cells in a number of mechanisms, and, to date, there have been innumerable reports in support of the role of lycopene against most known types of cancer.
Have you had your Lycopene today?

To fight off aging you have to understand what causes it, and the take steps to avoid these causes. It is fairly obvious that all causes of aging cannot be circumvented, but there are things that can be done to keep some of them at bay. Here, we are specifically concerned with the aging of your skin, which is the most visible form of aging. The first aspect of aging to understand is that there are two types: intrinsic and extrinsic.
Intrinsic aging is natural aging, and is largely genetic. Starting when you are fairly young, normally in the early to mid 20s, intrinsic aging is typified by wrinkling, hair loss or graying of the hair, hollowing of cheeks and other areas where the fat underneath the skin that normally contributes to your physical appearance is lost, and also bone loss that causes your skin to sag due a gradual loss of the structure that sculpts your physical appearance.
The age at which this occurs, and its speed is determined by your genes; although the process generally begins around the mid 20s, the speed with which it progresses is genetically controlled.
This is where grape seed extract can help. Extrinsic aging is not genetic, but environmental. Ten majority of this type of aging is due to exposure to the damaging UV light of the sun, which cause the typical 'leathery' look of the skin of people raised in areas such locations as the hotter parts of Australia and the USA, without the benefit of the native skin PIGMENTATION that filters out these harmful ultra-violet rays.
Other factors that can cause the same degradation of your skin cells are smoking, the way you sleep and gravity. The sun generates free radicals (more on these later) that can destroy skin cells, cause freckles, leathery skin and a blotched complexion and also skin cancer. Smokers are more likely to develop leathery and wrinkled skin than non-smokers, and as the elasticity of your skin reduces, gravity cause jowls to develop and also a more pronounced lower lip.
Even your sleeping position can make you appear to age quicker, particularly using the same sleeping position on your pillow each night that cause what are known as sleep lines, that are really wrinkles that are difficult, if not impossible to remove. However, one of the most relevant factors is pollution, and the effects of car emissions, pesticides and other agricultural chemicals, paint fumes and 1001 other forms of chemical pollution that produce free radicals.
Where grape seed extract is involved in fighting off aging is in extrinsic aging is by destroying the free radicals. All substances, from the air to the oceans, are formed of atoms that contain electrons. Stable molecules contain an even number of electrons, or what are known as 'electron pairs'. When a molecule loses one electron it is known as a free radical, whose prime purpose in its very short life is to steal an electron from the nearest molecule. This 'short' lifetime can as long as a day or as short as thousandth of a second: it depends on is size and the degree of steric hindrance to the reaction with the spare electron.
Now that the reasons for aging and the nature of free radicals are better understood it is easier for you understand why grape seed extract can help to fight aging caused by the effects of free radicals on your skin.
Grape seed is a waste product of the wine industry. You cannot make wine from grape seeds, so they are removed from the final product by filtration or sedimentation. It contains a large number of phytonutrients, the most important being polyphenols in the form of flavanoids, lipids and carbohydrates. It also contains proteins that don't have much of an effect on aging. Flavonoids (also spelled flavanoids) are powerful antioxidants that destroy free radicals; they are twenty times as powerful as Vitamin E and over fifty times more powerful an antioxidant than Vitamin C.
Both of these vitamins are regarded as strong antioxidants in their own right, which is an indication of how good grape seed extract is at killing free radicals. It's like a combination of Harry Callahan, Paul Kersey, John McClane and the whole of the Magnificent Seven after the scavengers in your body cells. They succeed, and do it in spades!
Not only do the ingredients of grape seed extract kill off free radicals with the efficiency of a Delta Task Force, but are also anti-allergenic, anti-inflammatory, anti-cancer and anti just about anything else you can think of. However, let's have an even closer look and find out exactly what polyphenols are present in this so-called wonder juice.
Procyanadin was originally named Vitamin P in 1936 by its discoverer, Prof. Jacques Masquelier, and is believed to bond with collagen to protect you from premature aging by retaining and even improving the elasticity of your skin. An added benefit is that it also improves the elasticity of your blood vessels, and so helps to fight off the effects of high blood pressure and places less strain on your heart. The overall effect on your face is to practically give you a chemical face lift and also provide protection from the damaging effect of the UV component of sunlight through its lethal attitude towards the free radicals that UV radiation generates.
Another component of grape seed extract particularly that of muscadine grapes is resveratrol; a phytoalexin that has strong anti-inflammatory properties and can also fight off the effects of aging. Phytoalexins are antibiotics produced by plants that are under attack, and, in addition to helping you age slower, confers other benefits to your body including helping your brain to carry out its work more efficiently.
All in all, grape seed extract confers many benefits to your health and is also believed to possess powerful anti-cancer properties. However, it is for its ability to fight off aging that most people use it as a supplement, and in this respect it has been found to be extremely effective. Any antioxidant is of benefit to your body, but grape seed extract is of particular benefit due its high antioxidant potency.

DL-Phenylalanine has been found to work in conjunction with the body’s natural ability to relieve pain. It helps to lengthen the lifespan of the chemicals in the brain that ease pain. It is especially effective in relieving pain from arthritis and aching muscles.
Some chronic pain can be treated with DL-phenylalanine through the stimulation of nerve pathways in the brain that control pain. Enhanced pain relief has been discovered when D-phenylalanine is used in conjunction with prescribed pain killers. This manufactured form of phenylalanine is used to block an enzyme in the nervous system that increases pain signals. The interruption of pain signals allows the healing mechanisms of the body to begin working faster.
DL-Phenylalanine is a chemical combination of half L-phenylalanine and half D-phenylalanine. L-Phenylalanine is the natural form of phenylalanine found in proteins all over the body. It is found in foods like beef, poultry, pork, fish, eggs, milk, yogurt, cheese, nuts, seeds and certain soy products. D-Phenylalanine is a synthesized form of the chemical, which means it is produced in a laboratory.
Phenylalanine as an Amino Acid:
Amino acids perform various major functions in the body. They assist in fulfilling the body’s basic needs from minerals and vitamins. They can act as neurotransmitters, which carry signals to and from the brain. They also aid in other parts of the body for communication between nerve cells.
Phenylalanine is one of the essential amino acids found in protein. This means it is required for human health, but cannot be manufactured by the human body. Therefore it has to be supplied through food consumption. It can also be found and taken in the form of powder, capsule, tablet or a topical cream. In the body, phenylalanine is converted into tyrosine, which is another amino acid needed to make protein. It is also needed to make certain brain chemicals and thyroid hormones. Phenylalanine deficiency signs include:
A rare disorder called phenylketonuria (PKU) happens in humans who are missing the enzyme required to metabolize phenylalanine. Symptoms of this disorder tend to appear between the ages of 3-6 months. These include:
If PKU is not treated within the first three weeks of life, it can cause severe and irreversible mental retardation. Women who are pregnant or nursing should avoid taking phenylalanine as a supplement in any form. DL-Phenylalanine may cause hyperactivity, jitteriness and anxiety in children.
Phenylalanine is the major ingredient in the artificial sweetener known as aspartame. Products containing this sweetener are required by law to carry warnings on their labels for phenylketonurics. People who have PKU can be severely injured by ingesting the sweetener. Products containing this artificial sweetener include diet sodas, sugarless gums and some sugar substitutes. Some sugar-free versions of Jello, puddings, ice creams, candies and various other items also contain aspartame.
Other Phenylalanine Uses:
Some individuals have reported that taking DL-phenylalanine has improved their mood and aided in treating depression. This is the result of a higher rate of production of the brain chemicals dopamine and norepinephrine. These chemicals, when out of balance, cause depression, stress and frustration. Elevation of the levels of these chemicals have an anti-depressant effect in the body.
One study suggests that D-phenylalanine has been shown to improve some symptoms associated with Parkinson’s disease. These include: depression, rigidity, walking problems and speech problems.
The combination of L-phenylalanine and UVA radiation may be used to treat the symptoms of vitiligo. This condition involves de-PIGMENTATION (white patches) of skin. The use of L-phenylalanine may help to re-pigment these patches, but further study is necessary.
DL-Phenylalanine has many uses and benefits if taken correctly. As with any new dietary supplement, consult your physician before beginning a new routine.
Beta Carotene Is The Safe To The Liver Form Of Vitamin A
March 19, 2008 08:17 AM
The fact that beta carotene is stated to be a safe form of vitamin A suggests that vitamin A is in some way unsafe. In fact an overdose of vitamin A can lead to any one of a number of conditions, including nausea, jaundice, vomiting, abdominal pain and headaches. This vitamin is fat soluble, and so any excess is not easily washed out of the body but can build up in the tissues.
Toxicity in the liver can occur at fairly low concentrations, and the toxicity of the vitamin is increased by excessive alcohol intake. However, toxicity only occurs with vitamin A already formed such as that obtained from liver.
There are several forms of vitamin A, including the retinoid form originating from animal sources and the carotenoid forms that have a vegetable origin. Carotenoids are converted to vitamin A in the liver, but the higher the concentration of beta carotene in the body, the smaller the percentage that is converted to vitamin A, so beta carotene is a safer source of vitamin A than retinoids. It is only the finished form of vitamin A that is toxic, and beta carotene is therefore self-regulating in its production.
This vitamin is stored in the body in the form of the alcohol (retinol) and of retinyl esters. Studies have indicated that as much as 95% if the stored vitamin is in the form of the ester. The liver is responsible for releasing vitamin A to the body as it is required. One of its better known effects is on vision, and the old wives tale that carrots help you to see in the dark has an element of truth in it.
In order for it to aid vision, retinol is oxidized to the aldehyde, retinal, that forms a complex with a molecule of opsin, a light sensitive protein found in the retina. Rhodopsin, as the complex is called, is an essential component of the biochemical chain of events that lead to the perception of light. It is extremely sensitive, and enables you see in very low levels of light. In other words it is essential for good night vision, so carrots do help you to see in the dark! When a photon of light hits a molecule of rhodopsin, it leads eventually to an impulse being sent up the optic nerve to the brain.
One of its properties is its reaction to white light. When rhodopsin is exposed to white light it loses its PIGMENTATION, and hence its photoreceptor properties and can take 30 minutes to regenerate. That is why you lose your night sight if your retina is exposed to bright light. The more rhodopsin you can generate the quicker you develop night sight.
The other biochemical processes of the vitamin include the synthesis of some glycoproteins and maintenance of normal bone density. Without vitamin A, calcium is not properly absorbed by the body and glycoproteins are involved in this process. A deficiency of vitamin A can lead to the abnormal development of bone and other health problems, so there are limits between the levels of vitamin A in the body that must be maintained: above or below these limits will lead to health problems, some of which can be extremely serious.
Most of the biochemistry of vitamin A in the liver is initiated by the presence of alcohol, and otherwise it is though to passively store the vitamin until needed when it is released into the blood. There are several ways in which the presence of alcohol allows the liver to deplete its store of retinol, but generally there are a number of enzymes that, in the presence of ethanol, can render vitamin A into a water soluble form that is excreted by the urine.
The benefits of vitamin A other than its effect on night sight and the healthy development of bone tissue, includes a powerful antioxidant effect that neutralizes free radicals that can destroy body cells. These free radicals are generated by the body’s metabolism in generating energy from blood glucose, and are also created through exposure to pollutants such as cigarette smoke and traffic fumes. They are electron deficient, so when they are generated they grab an electron from tissue close by which destroys the cells involved. This can lead not only to the appearance of premature aging as the skin cells are damaged but also to serious health problems such as atherosclerosis and some forms of cancer. Vitamin A helps to protect against these by destroying the free radicals before they can do damage. It also helps build up resistance against infections by supporting the immune system.
Beta carotene is converted to vitamin A either by cleaving at the center of the molecule, or by breaking it down from one of the ends. This latter process is carried out in the small intestine, and the resultant vitamin stored in the liver in the ester form. Only a proportion of what you eat is converted to retinol ester in this way, and the more beta carotene you consume, the less is converted, so you can never suffer from an overdose of beta carotene-derived vitamin A. It might turn you yellow, but you won’t suffer from excess vitamin A since the excess beta carotene is stored in your body fat, including the subcutaneous fat reserves.
Alpha carotene can also be used in the synthesis of vitamin A, but not as actively as beta carotene. The best natural sources are fruits and vegetables, especially the red, yellow and orange varieties such as carrots and apricots, and also the leafy green vegetables, although supplements are also a convenient way of maintaining your beta carotene uptake. It is a much safer supplement than straight vitamin A for the reasons explained earlier. The supplement is not useful just for its antioxidant effect, but also for its ability to protect you from excessive exposure to the sun. While not as effective as a good sun blocker, beta carotene does provide some protection.
There is no doubt that beta carotene is a safer way to maintain an adequate vitamin A uptake due to the fact that you cannot take an overdose, since an overdose of beta carotene does not translate into the same dose of vitamin A, and the change is self-regulating. It is therefore safer to obtain your vitamin A needs from colored fruits and vegetables or beta carotene supplements than from eating liver, from which the retinol is in a form that can cause damage in the event of consuming an excess.
The old adage that you should never eat polar bear livers is a true one, and certainly has a provable scientific basis, so use beta carotene as your main vitamin A source for maximum health benefits in the safest possible way.
