The Awesome Foursome: Coenzyme Q10, L-Carnitine,
D-Ribose, Magnesium
The “Awesome Foursome” of Coenzyme Q10, L-Carnitine, D-Ribose, and magnesium helps our hearts metabolize energy more efficiently and protects them from the stress of cardiovascular disease. This powerful combination of nutrients goes directly to the basic biochemistry of cellular energy metabolism. Now let’s take a closer look at how Coenzyme Q10, L-Carnitine, D-Ribose, and magnesium work in synergy to promote cardiovascular health.
Coenzyme Q10:
Energy Recycling through the Electron Transport Chain
Coenzyme Q10 is a powerful antioxidant that helps protect the mitochondrial membrane, mitochondrial DNA, and cell walls from free-radical attack. But its most important function in the body is its central role in energy metabolism.
Most – about 90 percent – of the ATP used by cells is recycled as food (fuel) and oxidized in the mitochondria. Fatty acids, carbohydrates, and, occasionally, proteins are carried across the mitochondrial membrane and enter the Krebs’ cycle, moving from step to step and spinning off electrons. These electrons are then handed off to the electron transport chain, where, in the presence of oxygen, the energy from the electrons is captured as a phosphate group is added to ADP to form ATP. This recycling of ATP is called oxidative phosphorylation, and the by-products of these pathways are CO2 and water.
In this fashion, Coenzyme Q10 acts as a gatekeeper of electrons, making sure they are carried to just the right place to pass on their life-giving energy.
What is critical, however, is the simple fact that without Coenzyme Q10 the electron transport chain would totally break down. And since the electron transport chain is (by far!) the largest contributor to cellular energy turnover, its loss would be catastrophic. It is also important to know that there has to be an excess of Coenzyme Q10 in the mitochondria to be maximally effective. Having just enough isn’t sufficient to do the job properly, and having a deficiency seriously affects the mitochondria’s ability to supply the cell with energy.
Cellular stress can cause Coenzyme Q10 deficiency, which places a severe strain on Coenzyme Q10 availability. People with heart disease, hypertension, gingival disease, Parkinson’s disease, and the other disorders we’ve discussed are known to be deficient in Coenzyme Q10. Whether these deficiencies are the cause or the effect of these varied medical problems, the end result is that they sap the life out of their mitochondria and reduce their energy supplies. You see, Coenzyme Q10 cannot function properly if electrons are not coming out of the Krebs’ cycle, and the Krebs’ cycle won’t work without the fuel that’s transported into the mitochondria by L-Carnitine.
L-Carnitine:
Transporting the Cellular Energy Fuel
Fatty acids are the preferred energy fuel for hearts and most other cells in the body. L-Carnitine facilitates the beta oxidation of fatty acids as energy fuel. And since fatty acids are the preferred fuel for energy recycling in cells, this action is critical to cell and tissue function. Unfortunately, L-carnitine is deficient in people with heart disease, peripheral vascular disease, lipid metabolic disorders, mitochondrial disorders, and many other disease syndromes we reviewed earlier. This L-carnitine deficiency disrupts the normal metabolism of fatty acids, reducing available energy supplies and leading to the accumulation of toxic by-products of fatty acid metabolism. L-carnitine supplementation revives fatty acid metabolism and restore normal mitochondrial function. But even this powerful improvement in cellular energy metabolism cannot up for the energy drain that comes from the loss of energy substrates caused by low oxygen delivery to the tissue. Only D-Ribose can do that.
D-Ribose:
Rebuilding the Cellular Energy Pool
As long as cells and tissues have plenty of oxygen, the pool of energy substrates in the cell remains high. And as long as there is enough L-carnitine and Coenzyme Q10 available, the process of energy utilization and supply can proceed unimpeded. However, the cellular supply of oxygen can be restricted by acute or chronic heart disease, peripheral vascular disease, any number of skeletal – or neuromuscular diseases, or even high-intensity exercise.
When cells are deprived of oxygen the mitochondrial energy turnover becomes inefficient. Remember, oxygen is required to let the oxidative pathway of energy recycling work properly. If the mitochondria are not able to recycle energy efficiently, cellular energy supply cannot keep pace with demand. But the cell has a continuing need for energy so it will use all its ATP stores and then break down the by-product, adenosine diphosphate (ADP), to pull the remaining energy out of this compound as well. What’s left is adenosine menophosphate (AMP). Since a growing concentration of AMP is incompatible with sustained cellular function it’s quickly broken apart and the by-products are washed out of the cell. The net result of this process is a depletion of the cellular pool of energy substrates. When the by-products of AMP catabolism are washed out of the cell, they are lost forever. It takes a long time to replace these lost energy substrates even if the cell is fully perfused with oxygen again.
Ribose is the only compound used by the body to refill this energy pool. Every cell in the body has the capacity to make ribose, but hearts, muscles, and most other tissues lack the metabolic machinery to make ribose quickly when the cells are stressed by oxygen depletion or metabolic insufficiency. Ribose is made naturally in the cells from glucose. In stressed cells, however, glucose is preferentially metabolized for the energy turnover and is not available for ribose synthesis. So when energy pools are drained from stressed cells, the cells must first wait for the slow process of ribose synthesis before they can begin to replace their lost energy stores.
Acute ischemia, like that which takes place during a heart attack, heart surgery, or angioplasty, drains the cell of energy. Even when oxygenated blood flow returns, refilling the energy pool may take ten or more days. But when oxygen deprivation is chronic, or when energy metabolism is disrupted by disease, there may be so much continual strain on the energy supply that the pool can ever refill without the assistance of supplemental ribose. Conditions like ischemic heart disease or congestive heart failure fall into this category. In these situations, supplementing the tissue with exogenous ribose is the only way the cell can keep up with the energy drain.
Magnesium:
Switching on the Energy Enzymes
Magnesium is an essential mineral that's critical for energy requiring processes, in protein synthesis, membrane integrity, nervous tissue conduction, neuromuscular excitation, muscle contraction, hormone secretion, maintenance of vascular tone, and in intermediary metabolism. Deficiency may lead to changes in neuromuscular, cardiovascular, immune, and hormonal function; Impaired energy metabolism; and reduced capacity for physical work. Magnesium deficiency is now considered to contribute to many diseases, and the role for magnesium as a therapeutic agent is expanding.
Magnesium deficiency reduces the activity of important enzymes used in energy metabolism. Unless we have adequate levels of magnesium in our cells, the cellular processes of energy metabolism cannot function. Small changes in magnesium levels can have a substantial effect on heart and blood vessel function. While magnesium is found in most foods - particularly vegetables - deficiencies are increasing. Softened water and a trend toward lower vegetable consumption are the culprits contributing to these rising deficiencies.
Supporting the Links in The Energy Cycle Chain – the Synergy
Clearly, each membrane of the “Awesome Foursome” is fundamental to cellular energy metabolism in its own right. Each plays a unique and vital role in supplying the heart with the energy it needs to preserve its contractile force. Each is independently effective in helping hearts work through the stress of disease. And while each contributes immeasurable to the energy health of the cell, in combination they are unbeatable. Allow me to reiterate the step-by-step, complicated cellular processes involved to be sure that you really understand the rationale for using these nutrients.
The cell needs a large, sustained, and healthy pool of energy to fuel all its metabolic functions. Contraction, relaxation, maintenance of cellular ion balance, and synthesis of macromolecules, like proteins, all require a high energy charge to carry their reactions to completion. The energy pool must be preserved, or these fundamental cellular functions will become inefficient or will cease to operate altogether. To keep the pool vibrant and healthy, the cell needs ribose. But even with supplemental ribose, the cell needs the efficient turnover of its energy stores to balance ongoing energy utilization with supply. That’s where CoQ10 and L-carnitine come into play.
The converse is also true. Even if the cell is fully charged with energy, cellular energy supply will not keep pace with demand if the mitochondria are not functioning properly. CoQ10 and L-carnitine work to keep mitochondrial operations running at peak efficiency, and one side cannot work effectively without the other. Even though CoQ10 and L-carnitine can make the energy turnover mechanisms work more efficiently, they cannot increase the cell’s chemical driving force, and their action will be only partially effective. Ribose on the other hand, can keep the energy pool supplied with substrate, but the value of energy pool repletion cannot be fully realized if the substrate cannot be maximally utilized and recycled. Ribose fills the tank; CoQ10 an L-carnitine help the engine run properly.
Magnesium is the glue that holds energy metabolism together. By turning on the enzymes that drive the metabolic reactions, magnesium allows it all to happen.
These four nutrients must be utilized by cardiologists and other physicians as they treat patients day-to-day. On my own journey, using Coenzymes Q10 for two decades, L-carnitine for more than ten years, D-Ribose for two years, and magnesium equally as long, I’ve seen this “Awesome Foursome” reduce suffering and improve the quality of life for thousands of patients.
The future of nutrition in conventional medicine is very bright, although the integration of nutritional supplements has been a slow and, at times, lonely process.
L-carnitine and Coenzyme Q10 are finally gaining the recognition they deserve. D-Ribose is emerging as a new player in the complex understanding of metabolic cardiology, and doctors are beginning to discuss the important role of magnesium deficiency in heart patients. As a practicing cardiologist for over thirty years, I see metabolic cardiology as the future for the treatment of heart disease and other complex disease conditions, as well.

CoQ10 is a vitamin-like compound that is produced naturally in the human body and is also found in most living organisms. It is also called ubiquinone, a combination of quinone, a type of coenzyme, and ubiquitous, meaning it exists everywhere in the human body. CoQ10 plays an important role in your body’s energy production and is an essential component of the mitochondria, where it helps to metabolize fats and carbohydrates and maintain cell membrane flexibility. CoQ10 is also involved in the production of several key enzymes that are used to create ATP, which is burned by your body for energy, and used in the energy transfer between mitochondria and cells. Without CoQ10, you would not be able to function! CoQ10 is also an effective antioxidant that may beneficially affect the aging process. As we age, our body’s production of CoQ10 declines by as much as 80 percent. Because it is so important to energy production, and therefore life, researchers believe that this decline may be a factor in the effects of aging on the human body. Clinical trials on both animal and human subjects have revealed a marked decrease in CoQ10 levels in relation to a wide variety of diseases. As a free radical scavenger, CoQ10 inhibits lipid peroxidation – a normal aspect of the aging process that is implicated in certain agerelated diseases. Studies conducted in the last fifteen years suggest CoQ10 is important for maintaining healthy intracellular activity, and some researchers have compared its efficiency to that of vitamin E, one of the most effective of all dietary antioxidants. Research has shown that CoQ10, along with glutathione and selenium, works to regenerate or recycle vitamin E after it’s capacity to fight radicals has been diminished, thereby allowing vitamin E to remain active as an antioxidant for a longer period of time in your body. CoQ10 was first discovered by Dr. Frederick Crane of the University of Wisconsin in 1957. One year later, Professor Karl Folkers and others at Merck Inc. identified and recorded CoQ10’s chemical structure, and were the first to produce it through fermentation. Intermittent research led to its use in Japan for cardiac insufficiencies during the 1960’s. Dr. Folkers championed more intensive research into CoQ10’s role in cardiovascular health in 1972, after he and an Italian scientist, Gian Paolo Littarru, discovered that persons with cardiac insufficiencies had very low levels of CoQ10, and supplementation increased CoQ10 levels and positively affected heart health. Soon afterwards, the Japanese developed a method that allowed pure CoQ10 to be produced in quantities large enough for significant clinical trials. During the 1980’s this method was perfected in Japan, and medical technology finally allowed scientists to measure CoQ10 levels in blood and tissues, leading to a surge in further research. It was during this time that a Swedish researcher, Lars Ernster, drew attention to CoQ10’s role as a free radical-scavenging antioxidant. Today a multitude of research supports CoQ10’s health benefits. As a result of the overwhelmingly positive reports from studies conducted since CoQ10’s discovery, the Japanese were the first to approve widespread use of CoQ10, granting market approval for it in 1974. From 1974 to 1982, CoQ10 use in Japan grew rapidly until it was one of the most widely used products in the Japanese pharmaceutical industry. It is still widely used today, and has a long history of safe use. In “An Introduction To Coenzyme Q10” by Peter H. Langsjoen, M.D., F.A.C.C., he lists the substantial amount of scientific evidence that supports CoQ10’s benefits. “Internationally, there have been at least nine placebo controlled studies on the treatment of heart disease with CoQ10: two in Japan, two in the United States, two in Italy, two in Germany, and one in Sweden. All nine of these studies have confirmed the effectiveness of CoQ10 as well as it’s remarkable safety. There have now been eight international symposia on the biomedical and clinical aspects of CoQ10 (from 1976 through 1993). These eight symposia comprised over 3000 papers presented by approximately 200 different physicians and scientists from 18 countries.” “The majority of the clinical studies concerned the treatment of heart disease and were remarkably consistent in their conclusions: that treatment with CoQ10 significantly improved heart muscle function while producing no adverse effects or drug interactions.” There are many CoQ10 supplements on the market today, and it can be difficult to choose the best brand and dosage. CoQ10 is a fat-soluble substance, which means it is more easily absorbed and used by your body in the presence of fat. CoQ10 supplements that include lecithin or another dietary fat will be more effective, and CoQ10 in a softgel form should be in an oil base, usually soybean oil. The dosage most commonly used in research is 30 mg, but higher doses are optimal and may be required to maintain optimal levels as we age. Always remember to consult your health practitioner before taking dietary supplements if you have current health problems or are taking prescription medication. Now Foods continues to be a leading supplier of high-quality, low cost CoQ10 products. In 1999 and 2003 NOW Foods CoQ10 was voted the best-selling brand in health food stores nationwide, earning the Vity Award from Vitamin Retailer magazine. NOW carries eight different effective potencies of CoQ10, ranging from 30mg to 400mg, in lonzenges, softgels, and vegetable capsules. Many of our formulas are complexed with other synergistic nutrients like vitamin E, selenium, lecithin, and hawthorn for greater absorption and efficiency.

Maximum Absorption by Henry Wolfe Energy Times, July 11, 2003 Nutrients do you no good if you don't absorb them. Eating the right stuff and taking the right nutrients can still be wrong if they never make it out of your digestive tract and into your bloodstream. For instance, dietary supplements usually should be taken along with food. The presence of food in the digestive tract aids the absorption of nutrients. As a general rule, if you take dietary supplements on an empty stomach, most of their contents will probably pass through you and never escape your intestinal tract before they are eventually eliminated. This is particularly true for the fat-soluble nutrients such as vitamins A, D and E. By consuming fatty foods when you take these supplements, you enable your body to absorb a large amount of these valuable substances. But there is at least one exception to this rule: Amino acid supplements (protein building blocks) should usually be taken on an empty stomach. Otherwise the other amino acids present in your meal may interfere with your use of these nutrients and counteract the benefits of the supplements. The Standardization of Herbs Taking herbs presents different challenges than consuming dietary supplements. While the chemical structures of nutrients in supplements are usually precisely identified, the active ingredients in herbs is usually a mixture of chemicals. Often, too, researchers disagree on exactly which active ingredients in herbs produce the health benefits linked to these botanicals. But in an effort to derive the most from these substances, many experts recommend what are called standardized forms. Standardized herbal supplements are formulas that have been created to insure they contain consistent and reliable amounts of certain beneficial chemicals that scientists have identified in these plants. In the creation of these supplements, experts determine the standardized chemicals that are most likely the basis of the herbs' effectiveness. By standardizing certain of the supplements' ingredients, therefore, standardized herbs limit the variation among batches of the product. You can rely on the fact that every purchase will contain the same amount of ingredients taken from the original plant. According to Michael Janson, MD, author of Dr. Janson's New Vitamin Revolution (Penguin/Avery), "Although herbs have a long history of use for medicinal purposes, it is only recently that they have been analyzed to reveal their most active components. These active chemicals are commonly present in very variable amounts in herbs, depending on where and how they are grown, soil quality, when they are harvested, the amount of rain and sun, and other factors. "Standardized herbs have guaranteed specific amounts of the known, active herbal components, as well as the other factors that might be of help but are not as well studied" (www.drjanson.com). Herbalists who specialize in using entire plants in their practices can recommend non-standardized preparations that you can often use. In general, that kind of herbal use is more effective when you secure expert advice. If you lack access to an experienced herbalist and you're choosing botanicals on your own, standardized preparations are easier to take. Absorption From the Gut Most of the nutrients you take in are absorbed through the walls of your digestive tract. This most often takes place in the small intestine. What to watch out for: Fast food, fast living and long work hours afflicts our digestion and can disrupt proper absorption. You have to be relaxed to properly absorb the nutrients in your food and supplements. Consequently, the occasions for meals should be relaxed and enjoyable moments. Set aside enough time to appreciate, taste and thoroughly chew your food. Adequate digestion and absorption begin in your mouth. Another way to increase nutrient absorption is with the use of digestive enzymes. Since the digestive tract depends on the enzymatic breakdown of food that reduces nutrients to absorbable form, taking enzymes can help your intestines make better use of nutrients as they pass through the digestive tract. Normally, enzymes are present in raw food, like uncooked fruits and vegetables. Since most of our food is eaten after it is heated, a process that breaks down enzymes, not many enzymes are present in today's diet. Therefore, taking supplemental enzymes may increase absorption. Beyond Stress Beyond everyday stress, a variety of problems can make absorption go astray, allowing important nutrients to escape and permitting unwanted substances to enter the body. For instance, a significant digestive malfunction that many experts have focused on in recent years is a condition that has come to be called "leaky gut." As Anil Minocha, MD, director of digestive diseases at the Mississippi Medical Center and author of Natural Stomach Care (Avery), points out, "In a healthy individual, the wall of the intestinal tract is designed to absorb food molecules and prevent harmful microorganisms and toxic materials from passing out through the bowel wall and into the bloodstream. "In today's heavily polluted environment, the gastrointestinal tract of even the healthiest individual is called on to process an overwhelmingly large flow of septic and infectious materials." Because of these digestion destroyers, as we take in a startlingly large amount of viruses, bacteria, toxic chemicals, fungi and processed foods, our digestive systems are often overwhelmed and are rendered unable to perform their tasks correctly. This constant assault on the stomach and intestines takes a serious toll. A frequent product of this process is the digestive walls' loss of their crucial ability to keep out unwanted toxins and organisms as they become, in Dr. Minocha's words, "loosened and inflamed." As a result, instead of keeping out harmful substances and absorbing helpful nutrients, spaces open up that begin to allow in "bulky, partially digested food particles, toxic substances and infectious microbes." According to Dr. Minocha, the first signs of this absorption problem can include complaints such as allergic reactions, skin problems, joint pain, digestive difficulties, nausea, fatigue and lack of energy. To improve your digestive absorption, Dr. Minocha recommends a six-part program that includes these steps: * Detoxification by means of fasting and avoiding harmful items like sugar, over-processed foods, coffee and alcohol * Taking herbs that can help the digestive tract heal, recover and repair itself; these include garlic, ginger and milk thistle * Replenishing the beneficial bacteria of the digestive tract by eating yogurt * Keeping track of your daily diet and eliminating foods that cause allergies and other reactions * Consuming more fruits and vegetables while eating a high-fiber, mostly vegetarian diet * Developing consistent, healthy lifestyle habits; these include not smoking, cutting the size of your meals and eating in moderation, exercising several times a week and controlling stress Young and Old Digestion The nutrients in your diet can also beneficially influence the state of your digestive system and its ability to distinguish among substances that are supposed to gain entrance to your body and those that should be kept out. Since aging can further compromise the discriminatory ability of your gut, Dr. Minocha also recommends a steady diet of antioxidant-rich fruits and vegetables plus supplements to keep your digestive tract functioning at full capacity as you grow older. Among the nutrients he recommends: * Coenzyme Q10: By middle age, your body makes less of this powerful antioxidant that helps cells generate energy in the mitochondria (structures within cells that may decrease with age). Dr. Minocha notes that research demonstrates CoQ10 may be able to help people with diabetes control harmful metabolic byproducts that appear in their bloodstreams. * Natural Lycopene: This antioxidant, responsible for the red of both tomatoes and watermelon, has been shown to lower the risk of both heart disease and prostate cancer. As an antioxidant, natural lycopene also helps protect the digestive tract. Absorption of the proper nutrients may be the key to health for many people. By paying closer attention to the well-being of your digestive tract and practicing lifestyle habits that promote maximum absorption, you may be able to substantially improve your nutrition and your health.

Today’s modern lifestyle, filled with stress, pollution, overprocessed and fatty foods, and lack of exercise, places great strains on the cardiovascular system. Source Naturals HEART RESPONSE is a broad-range formula that supports cardiovascular health, especially heart muscle contraction, healthy circulation and the generation of cellular energy. HEART RESPONSE features clinical potencies of the renowned heart botanical, hawthorn, and significant amounts of the energy nutrients, coenzyme Q10 and carnitine, along with additional nutrients and herbs. Each daily use supplies 600 mg of hawthorn, the same amount used in recent research. Supports Heart Health HEART RESPONSE was formulated to include key nutrients and herbs known to support the cardiovascular system. Hawthorn: Hawthorn, a rich source of flavonoids and procyanidins, has been used traditionally all over the world as a strengthening circulatory and heart tonic. Modern research has documented that hawthorn increases coronary blood flow and strengthens the contraction of heart muscle. Hawthorn is also an antioxidant, which scavenges and neutralizes destructive free radicals. It is only when cholesterol is oxidized that it impacts the integrity of arteries. Coenzyme Q10: HEART RESPONSE supplies 60 mg daily of CoQ10, a key enzyme in the Electron Transport Chain, the pathway that generates 90% of the ATP “energy currency” needed by the body. Heart muscle requires huge amounts of energy to perform efficiently—it beats more than 100,000 times each day, pumping more than 1,000 gallons of blood through the body. The heart utilizes ATP as an energy source for muscular contraction. CoQ10 also is a fat-soluble antioxidant. L-Carnitine: Carnitine is an amino acid-derived substance that supports heart muscle metabolism. Carnitine is needed to carry long chain fatty acids into the cell mitochondria, where they undergo oxidation to generate energy. The heart utilizes fatty acids as a preferred energy source for its metabolism. HEART RESPONSE delivers 300 mg per day of carntine. Taurine and Magnesium: Magnesium and taurine work closely together in the body to help maintain the normal electrical rhythm of the heart. Taurine comprises more than 50% of the free amino acid pool in our hearts, and has many electrophysiological effects on cardiac muscle cells. Alterations in magnesium levels can have profound effects on the heart. Magnesium is involved in autonomic control of the heart through several mechanisms. Bromelain: Bromelain is an enzyme mixture prepared from pineapple stems. Pineapple has been used for its health benefits for more than 500 years. Grape Seed Extract: Grape seed is a source of procyanidins. These plant constituents are strong antioxidants that inhibit lipid peroxidation and scavenge free radicals. In vitro studies have demonstrated that procyanidins support the integrity of connective tissue. Garlic: The use of garlic for its health benefits predates written history. Garlic’s volatile oil includes sulfur-containing compounds such as allicin, which are considered to be important biological constituents. Selenium: Selenium is an essential trace mineral that is necessary for the activity of the important antioxidant glutathione. Antioxidants are crucial for protecting cholesterol from oxidation, which in turn helps to maintain healthy blood vessels. B-Vitamins: Preventing an undesirable buildup of homocysteine levels may help support the integrity of arteries. Vitamins B-6, B-12 and folic acid are critical to the regulation of homocysteine levels. You can count on Source Naturals’ expert formulators to bring you a product based on the most up-to-date nutritional research. HEART RESPONSE combines traditional botanicals and cutting-edge nutrients, scientifically formulated to deal with many aspects of cardiovascular health. It is available in bottles of 30, 60 and 90 tablets.
