Cholesterol Conundrum by Jane Lane Energy Times, February 7, 1999 The cholesterol story packs enough subplots to satisfy a soap opera. There's Cholesterol: The Good, the Bad and the Awful. Cholesterol: The Stalker Behind Every (Restaurant) Door. Cholesterol Steals Your Heart Away-to the Mediterranean. The very image of cholesterol chills the imagination. Lurid and unsavory, it would seem to bob through the bloodstream like blobs of fat congealed on cold soup, slathering itself onto arteries. Cholesterol is in fact a normal, natural substance in our bodies, found in the brain, nerves, liver, blood and bile. Cholesterol is so crucial that each cell is equipped with the means to synthesize its own membrane cholesterol, regulating the fluidity of those membranes when they are too loose or too stiff. We manufacture steroid hormones-the female hormones estrogen and progesterone, and the male hormone testosterone-from cholesterol. Adrenal corticosteroid hormones, which regulate water balance through the kidneys, and the hormone cortisone, the vital anti-inflammatory that also governs our stress response, come from cholesterol. Other jobs of cholesterol: production of vitamin D and bile acid (for the digestive process); healing and protecting skin, and antioxidant compensation when vitamin and mineral stores are low. How can mere mention of this invaluable component in our body chemistry make our blood run cold? Guilt by Association Cholesterol's reputation as a bad character actually originates in the crowd it runs with: the lipoproteins, protein molecules to which it binds in order to travel back and forth through the bloodstream to the liver, where it is manufactured. Not really a nasty round glob of fat at all, cholesterol is a crystalline substance, technically a steroid, but soluble in fats rather than water, thus classified as a lipid, as fats are. Thousands of cholesterol molecules bind with lipoproteins, spherical fat molecules that transport them through the bloodstream. Three different kinds of lipoproteins participate in this necessary process, not always with the same salutary effect. Here's how they work: High-density lipoprotein (HDL): referred to as the "good cholesterol." Carries relatively little cholesterol. Travels through the bloodstream removing excess cholesterol from the blood and tissues. HDLs return the surplus to the liver, where it may once again be incorporated into low-density lipoproteins for redelivery to the cells. Low-density lipoprotein (LDL): the so-called "bad cholesterol," heavily laden with cholesterol, hauling it from the liver to all cells in the body. Ideally, this system should be in balance. But if there is too much cholesterol for the HDLs to pick up, or an inadequate supply of HDLs, cholesterol may aggregate into plaque groups that block arteries. Lipoprotein(a), or Lp(a): the "really bad" cholesterol, can step in, providing the glue that actually sticks to the arterial wall. Lp(a) is an LDL particle with an extra adhesive protein wrapped around it, enabling it to attach fat Globules to the walls of blood vessels. The potentially deadly results are atherosclerotic ("plaque") deposits. Simple LDL lacks adhesive power and presents little risk for cardiovascular disease. Researchers confirmed the existence of Lp(a) in the August 1996 issue of the Journal of the American Medical Association, disclosing that high levels of Lp(a) in the blood can double a man's risk of heart attack before age 55. Doctors estimate that about 20% of all Americans carry elevated levels of Lp(a). One troubling aspect of the report, part of the ongoing 40-year-old Framingham Study, concerned the fact that the men who suffered heart attacks entered the project with no signs of heart disease and only slightly elevated cholesterol. But during the 15-year investigation, 129 men out of 2,191 developed premature heart disease. The culprit? High levels of Lp(a) Experts don't know for certain where Lp(a) comes from, or its normal function, although they suspect the body's quotient of Lp(a) is mostly due to your genes. According to the study, they also believe that aspirin, a blood thinner, and red wine (or its grapeseed and skin extracts) may mitigate the damage of Lp(a). That also would explain why the French, who tend to wash down their fat-rich diet with red wine, experience a relatively moderate incidence of cardiovascular disease The Terrible Triglycerides The body also transports fats via triglycerides (TGs), the main form of body fat and the storehouse for energy. Edible oils from seeds, egg yolk and animal fats also are composed chiefly of TGs. Although not as corrosive as LDL, excess TGs intensify heart disease potential when they oxidize and damage artery linings or induce blood cells to clump. An "acceptable" level of triglycerides is thought to be 200 milligrams, although under 150 is probably healthier. And some researchers think your triglyceride reading should be below 100. High triglycerides and low HDL often occur together, increasing the risks of cardiovascular disease, high blood pressure, heart and kidney failure and other degenerative diseases. What To Do About Your Cholesterol Have it checked. High cholesterol alone shows no symptoms. Your health practitioner can perform a laboratory test to measure your levels. Thoroughly share your own medical history and as much as you know about your family members: heredity and related illnesses definitely are important influences. People with diabetes, for example, can have high levels of triglycerides, which also may lead to pancreatitis (painful inflammation of the pancreas) at extremely high levels. According to the National Cholesterol Education Program, a reading of under 200 mg/dL is desirable; 200 to 239 is borderline high; 240 and above is high. Your LDL level should be 130 or under; HDL should not be lower than 35. A triglyceride level below 200 is considered desirable; readings above 400 are high. Adjust your diet. Cholesterol levels are readily controllable, primarily through changes in your diet. Leslie C. Norins, MD, PhD, suggests all-out war in his Doctor's 30-Day Cholesterol Blitz (Advanced Health Institute) with saturated fats, which raise cholesterol more than any other component in your diet, as your number-one target. Out with saturated fats like butter, cheese, whole milk, ice cream, red meat and some vegetable fats found in tropical oils like coconut and palm; in with fruits, vegetables, brown rice, barley (a good source of soluble fiber, the kind that soaks up fats and cholesterol and escorts them out of the body), beans, potatoes and pasta, prepared or dressed with monounsaturated fats in olive and canola oils (the so-called Mediterranean diet concept). Feast on cold-water fish (mackerel, salmon, sardines and herring) rich in omega-3 fatty acids that help reduce serum lipids, among many other healthful advantages. Exercise. Move it and lose it are the words to live by when it comes to cholesterol. Researchers from the Stanford Center for Research in Disease Prevention reported in the July 2, 1998 New England Journal of Medicine (vol. 339, pages 12-20) that a weight-loss diet like that of the National Cholesterol Education Program plus exercise significantly lowered LDL (bad) cholesterol levels for men and postmenopausal women. The diet alone failed to lower LDL in these folks with high-risk lipoprotein. Educate yourself. In addition to your health practitioner, books and magazines can guide you in cholesterol management.

Your heart is crucial to every function of your body. It is the sole organ which pumps oxygen-rich blood through the entire circulatory system, feeding your cells and making life possible. Only recently are Americans realizing the importance of a proper low-fat diet, regular exercise, giving up cigarette smoking, and cutting down alcohol consumption to maintaining a healthy heart. Unfortunately, there has been a huge gap in the number of nutritional supplements which provide nutrients and herbs to support normal heart function. That’s where Source Naturals HEART SCIENCE comes in. Two years in the making, and backed by numerous scientific studies, the nutrients in HEART SCIENCE are some of the most soundly researched of all. Combining high potencies of these super-nutrients, HEART SCIENCE is the most comprehensive, cutting edge nutritional approach to proper heart care available. Source Naturals HEART SCIENCE— The Five Tiered Approach to Heart Health
Your heart never rests. Even while you sleep, your heart must keep working, relying on the constant generation of energy by the body for its very survival. If this vital organ stops beating for even a short amount of time, all bodily functions cease and life ends. Source Naturals HEART SCIENCE helps support heart function on the chemical, cellular, structural, and energetic levels. This broad spectrum formula includes ingredients specifically geared for Energy Generators for An Energetic Organ Every day, the human heart beats about 104,000 times, pumping over 8,000 liters of blood through the body! Because it requires so much energy to perform efficiently, the experts at Source Naturals included specialty nutrients in HEART SCIENCE such as Coenzyme Q10 and L-Carnitine — integral factors in the body’s energy production cycles — to enhance the body’s energy supply. There are three main interconnected energy generating cycles in our cells — the Glycolytic (sugar-burning) cycle, the Krebs’ (citric acid) cycle, and the Electron Transport Chain. Together they supply about 90 to 95% of our body’s entire energy supply, using fats, sugars, and amino acids as fuel. Coenzyme Q10 is one of the non-vitamin nutrients needed to maximally convert food into ATP (the energy producing molecule). It is the vital connecting link for three of the four main enzyme complexes in the Electron Transport Chain, the next step in energy generation after the Krebs’ cycle. Using the raw materials generated by the Krebs’ cycle, the Electron Transport Chain produces most of the body’s total energy! The heart is one of the bodily organs which contains the highest levels of CoQ10, precisely because it needs so much energy to function efficiently. CoQ10 is one of the most promising nutrients for the heart under investigation today. It has been postulated that as a result of its participation in energy production, CoQ10 improves heart muscle metabolism and the electrical functioning of the heart by enhancing its pumping capacity.8 Many factors such as a high fat diet, lack of exercise, and cigarette smoking can lead to suboptimal functioning of the heart, and therefore failure of the heart to maintain adequate circulation of blood. Interestingly, people whose lifestyles reflect the above factors also tend to have depleted levels of CoQ10 in the heart muscle.10 Researchers suggest taking between 10-100 mg per day of CoQ10;18,29 HEART SCIENCE provides an impressive 60 mg of CoQ10 per 6 tablets. Similar to CoQ10, L-Carnitine is important for energy production in heart cells. It is a natural amino acid-like substance which plays a key role in transporting fatty acids, the heart’s main source of energy, to the mitochondria, the “power plants” of each cell, where they are utilized for the production of ATP. Heart and skeletal muscles are particularly vulnerable to L-Carnitine deficiency. Studies have shown that supplementation with LCarnitine improves exercise tolerance in individuals with suboptimal heart and circulatory function, and seems to lower blood lipid status and increase HDL (good) cholesterol.16, 22 Each daily dose of HEART SCIENCE contains 500 mg of this extremely important compound. Like CoQ10 and L-Carnitine, B Vitamins help improve the ability of the heart muscle to function optimally. Each B Vitamin, after being converted to its active coenzyme form, acts as a catalytic “spark plug” for the body’s production of energy. Vitamin B-1, for example, is converted to Cocarboxylase, which serves as a critical link between the Glycolytic and Krebs’ Cycles, and also participates in the conversion of amino acids into energy. A deficiency of B coenzymes within contracting muscle cells can lead to a weakened pumping of the heart.21 HEART SCIENCE is formulated with high quantities of the most absorbable forms of B Vitamins providing maximum nutrition for the high energy demands of heart cells. Homocysteine Regulators B Vitamins also play a crucial role in the conversion of homocysteine, a group of potentially harmful amino acids produced by the body, to methionine, another more beneficial amino acid. While it is normal for the body to produce some homocysteine, even a small elevation in homocysteine levels can have negative implications. It is well documented that individuals who are genetically predisposed to having elevated homocysteine levels (homocysteinemics) tend to have excessive plaque accumulation in the arteries and premature damage to endothelial cells (cells lining the blood vessels and heart).26 Researchers have found that even those without this genetic abnormality, whose homocysteine levels are much lower than those of homocysteinemics, still have an increased risk for premature endothelial damage and the development of plaque in the arteries.24, 26 One study conducted among normal men and women found that those with the highest levels of homocysteine were twice as likely to have clogged arteries as were those with the lowest levels.24 Furthermore, it was found that the lower the research subjects’ blood levels of folate and B-6, the higher their homocysteine levels.24 Another study found that Folic Acid administered to normal men and women who were not even deficient in folate caused a significant reduction in plasma concentrations of homocysteine!3 In order to regulate homocysteine levels, it is critical to provide the body with sufficient amounts of B-6, B-12, and Folate, whether through the diet or through supplementation. HEART SCIENCE includes high levels of these three nutrients, providing B-6 in the regular and coenzyme form for maximum utilization. The Dangers of Oxidized LDL Cholesterol While many people have heard that high cholesterol levels may negatively affect normal heart function, few people understand exactly what cholesterol is, or how it can become harmful. Cholesterol is a white, waxy substance produced in the liver by all animals, and used for a variety of necessary activities in the body. Your liver also manufactures two main kinds of carrier molecules which transport cholesterol throughout the system: Low Density Lipoprotein (LDL) and High Density Lipoprotein (HDL). Cholesterol is either carried out by LDL from the liver to all tissues in the body where it is deposited, or carried back by HDLs which remove cholesterol deposits from the arteries and carry them to the liver for disposal. Because of this, LDL cholesterol is considered damaging, while HDL is considered protective. Problems occur when there is too much LDL cholesterol in the body and not enough HDL. When the body becomes overloaded with fat, an over-abundance of LDL particles are manufactured to process it, and they in turn become elevated in the body to a degree that the liver cannot handle. Rich in fatty acids and cholesterol, these particles are highly susceptible to free radical attack (oxidation). Once oxidized, LDL particles are no longer recognized by the body, which attacks them with immune cells. Immune cells which are bloated by oxidized lipids (called foam cells) are a key factor in the development of “fatty streaks” — the first sign of excess arterial fat accumulation. The bloated immune cells accumulate in artery lesions and create plaque in blood vessels, leading to obstruction and constriction of the vessels. Plus, these lodged foam cells continue to secrete free radicals into the bloodstream, making the problem worse. The development of lesions in the arteries is not an uncommon problem. Arterial (and all blood vessel) walls are composed of a chemical matrix which holds the endothelial cells in place. That endothelial layer is the first and most important line of defense in preventing large molecules, such as cholesterol and fat, from entering the vessel wall. This matrix is composed of proteins, collagen, elastin, and glycosaminoglycans (amino sugars). Arterial lesions can be caused by suboptimal collagen and elastin synthesis due to three factors: 1. Vitamin C deficiency (since Vitamin C is a key building block for collagen and elastin); 2. excessive consumption of rancid fats, or heavy usage of alcohol or cigarettes; and 3. free radical damage. Once these lesions are created, the body attempts to repair them by depositing LDL cholesterol — similar to the way one would patch a tire. If that cholesterol is not oxidized, i.e. chemically changed to a harmful, unstable molecule, then this process does not create a problem. But when arterial lesions are “patched” with foam cells, arterial walls suffer page 3 page 4 even more damage, because those foam cells release free radicals which can further damage cell membranes. Unfortunately, most people have a lot of oxidized cholesterol floating through the bloodstream. The typical American diet, with its low antioxidant intake and overconsumption of fried and overcooked foods, contributes to the overall levels of harmful oxidized cholesterol. In fact, the average American intake of antioxidants is low even by USRDA standards, making Americans particularly prone to having high levels of oxidized cholesterol. Cholesterol Fighters Fortunately, there are concrete steps you can take to prevent the oxidation of cholesterol, and its subsequent ill effects on health. In addition to cutting out high-cholesterol and fatty foods, supplementation can protect existing cholesterol and all tissue cells — from oxidation. Antioxidants, substances which scavenge and neutralize free radicals, protect the cardiovascular system by halting the oxidation of cholesterol, and helping to prevent plaque accumulation in the arteries and the continual secretion of free radicals by foam cells. Supplementing the diet with high amounts of Vitamin C, a key antioxidant, also encourages a more healthy “patching” of existing lesions by using collagen (made from Vitamin C) instead of cholesterol. HEART SCIENCE contains generous amounts of the following antioxidants for their protective benefits: The Regulating Trio Three nutrients — Magnesium, Potassium, and Taurine — work closely together in the body to help maintain the normal electrical rhythm of the heart, promote proper fluid balance, and prevent excessive Calcium levels from building up in the heart and artery linings. Artery Lining Protectors Your arteries form an integral part of your cardiovascular system, carrying blood away from the heart to nourish other parts of the body. In a healthy heart, blood surges through the arteries with every beat of the heart. The arteries expand with each pulse to accommodate the flow of blood. When arteries become hardened and narrowed by the build-up of plaque, they can’t expand and are not able to transport blood efficiently throughout the body. This inability to open up increases blood pressure, putting a strain on the heart as well as the arteries. HEART SCIENCE includes ingredients specifically geared to protect against plaque formation within arteries and maintain the flexibility of these vital blood vessels. N-Acetyl Glucosamine (NAG) is a key amino sugar which forms the building blocks of mucopolysaccharides. Mucopolysaccharides, which are long chain sugars, are an integral component of connective tissue. They combine to form gel-like matrixes which are present throughout tissues in the body, helping to maintain the elasticity of blood vessels which must continually adapt to the changing pressures of blood flow. Each daily dose of HEART SCIENCE provides 500 mg — a substantial amount — of this vital tissue building block. There is evidence indicating that Silicon, a natural mineral, may protect against plaque formation in the arteries. Silicon is found mainly in connective tissues, where it helps bind the body’s chemical matrix. Bound Silicon is found in high amounts in arterial walls. Researchers have found that there is a steady decline in the Silicon content of the aorta and other arteries as we age. This may be due to the low fiber content of the typical American diet, since fiber is a key dietary source of Silicon.23 HEART SCIENCE includes 400 mg of Horsetail herb extract, a natural source of Silicon. Hawthorn Berry is without question the herb most widely used to encourage normal heart function. The beneficial actions of Hawthorn Berry on cardiac function have been repeatedly demonstrated in experimental studies. Supplementation with Hawthorn Berry has been shown to improve both the blood supply to the heart by dilating coronary vessels, and the metabolic processes in the heart, resulting in normal, strong contractions of the heart muscle.34 Also, Hawthorn may inhibit the angiotensen converting enzyme, which is responsible for converting angiotensen I to angiotensen II, a powerful constrictor of blood vessels.34 Bromelain, a natural enzyme derived from pineapples, has become well-known for its neuromuscular relaxing properties. Researchers have reported favorable results when using Bromelain for soothing vascular linings. Initial research also indicates that Bromelain may break down fibrin, the glue which holds platelets together to form blood clots.6 Capillary Strengtheners Capillaries are the smallest, yet some of the most important, blood vessels. If you think of your cardiovascular system as a series of roads which transport blood and oxygen, then your arteries are akin to interstate highways, your arterioles are the main city boulevards, and your capillaries are local residential streets. Capillaries are so small, in fact, that single red blood cells actually have to fold up to fit through them. Because of their tiny size and the intricate nature of their network throughout the body, capillaries are responsible for actually nourishing each individual tissue cell! Along the length of the capillaries are small openings called slit pores through which oxygen, glucose, and nutrients leave the capillaries and enter the surrounding interstitial fluid. From there, they cross cell membranes and nourish the cells. Similarly, the waste products of cells enter the fluid and cross over into the capillaries, where they are then transported to the liver and kidneys for disposal. If the capillary slit pores are torn or have lesions, then blood proteins and Sodium will leak out and cause the interstitial fluid to take on a more gel-like nature. This makes the transfer of oxygen and nutrients to the cells more difficult, as well as the disposal of cell waste products, turning the fluid into a stagnant swamp instead of a flowing river. In addition to its powerful antioxidant actions, Proanthodyn also helps protect collagen and elastin, the main constituents of tissue in the capillaries, and throughout the body. It is absolutely essential for capillary walls — which are only one cell thick — to be strong and stable, so that they do not allow blood proteins to leak into the interstitial fluid. Once the interstitial fluid takes on a gel-like consistency, the surrounding cells literally become starved from lack of nutrition. The exciting news is that the proanthocyanidins contained in Proanthodyn are among the few substances yet discovered which can help strengthen capillary walls, ensuring the liquid nature of the interstitial fluid.2 Plus, proanthocyanidins help keep capillary and artery walls flexible, allowing for proper blood flow to the heart. Heart Smarts The 1990’s mark a decade of increased awareness among Americans of important health issues. Much of the discussion has revolved around protecting that precious center of life we call the heart. Simple lifestyle change is one of the most effective ways to maintain and protect the functioning of the cardiovascular system. In order to take a holistic approach to heart care, make sure you include plenty of fresh fruits and vegetables (organic, if possible) in your diet, and cut down on fatty and cholesterol-forming foods. Reduce your salt and alcohol intake to a minimum. Try to get regular, sustained aerobic exercise for at least 30 minutes three times a week. Don’t smoke – or if you do smoke, try to eat even more fresh fruits and antioxidant-rich vegetables to counter the amount of free radicals being produced in your body. Lastly, consider adding Source Naturals HEART SCIENCE to your health regimen. HEART SCIENCE, the most comprehensive formula of its kind, provides targeted protection to the entire cardiovascular system. By approaching the promotion of normal heart function on five different levels — through the inclusion of ingredients which supply energy, decrease harmful homocysteine levels, fight cholesterol build-up, help regulate electrical rhythm, and protect artery and capillary linings — HEART SCIENCE is the perfect addition to a holistic approach to heart care.
