High Absorption Magnesium contains elemental magnesium chelated with the amino acids glycine and lysine. It is a "di-peptide" chelate, which means that each magnesium atom is chelated with two amino acid molecules. It has a low molecular weight of 324 daltons, which is ideal for optimum absorption. As an essential dietary mineral, magnesium plays many important roles. It acts as a co-factor for metabolic enzymes; assists energy production in cells; supports nerve and muscle function; helps maintain a normal, regular heartbeat; and supports bone density. Bioperine is a patented herbal extract that enhances nutrient absorption.*
Magnesium participates in numerous life-essential processes that occur both inside and outside cells. Magnesium deficiency impacts normal physiologic function on many levels. Adequate magnesium is a fundamental requirementfor optimum function of the cardiovascular system, the nervous system and skeletal muscle, as well as the uterus and GI tract. Magnesium deficiency can affect health of the heart, bones and blood vessels and alter blood sugar balance.*
Magnesium–Important for Everyone, Deficient in Many The average person living in a modern country today very likely consumes less than the optimum amount of magnesium. An abundance of data collected over the last two decades shows a consistent pattern of low magnesium intake in the U.S. This pattern cuts a wide swath across various age-sex groups. The USDA’s Nationwide Food Consumption Survey found that a majority of Americans consumed less than the recommended daily magnesium intake. Twelve age-sex groups were studied and this low magnesium intake was true for all groups except 0 to 5 year olds.
An analysis of the diets of 7,810 individuals age four and above listed magnesium among several nutrients that, in the average diet, "were not sufficient to meet recommended standards". The FDA’s Total Diet study examined the intakes of eleven minerals, including magnesium, among eight age-sex groups. Data was collected four times yearly from 1982 to 1984. Levels of magnesium, calcium, iron, zinc and copper were low for most age-sex groups. Surveys conducted in Europe and in other parts of North America paint a similar picture. Loss of magnesium during food processing is one explanation for this global lack of adequate dietary magnesium.*
In particular, the elderly may be susceptible to magnesium deficiency for a variety of reasons, including inadequate magnesium intake, poor absorption due to impaired gastrointestinal function, and use of drugs such as diuretics that deplete magnesium from the body. It has recently been theorized that magnesium deficiency may contribute to accelerated aging through effects on the cardiovascular and nervous systems, as well as muscles and the kidneys.*
Women who take both synthetic estrogen and calcium supplements may be at risk for low blood levels of magnesium. Estrogen promotes the transfer of magnesium from blood to soft–tissues. Low blood magnesium may result if the ratio of calcium to magnesium intake exceeds 4 to 1. Magnesium supplementation is thus advisable for women taking estrogen and calcium.*
Young adults are not immune to magnesium deficiency. The University of California’s Bogalusa Heart Study collected nutritional data from a cross-sectional sample of 504 young adults between age 19 and 28. The reported intake of magnesium, along with several other minerals and vitamins, was below the RDA.
Glycine is a highly effective mineral chelator. This is because it is a low-molecular-weight amino acid and is thus easily transported across the intestinal membrane. A study conducted at Weber State University found this particular magnesium glycinate was absorbed up to four times more effectively than typical magnesium supplements.*
Magnesium-the Versatile Mineral The average adult body contains anywhere from about 21 to 28 grams of magnesium. Approximately 60 percent of the body’s magnesium supply is stored in bone. Soft tissue, such as skeletal muscle, contains 38%, leaving only about 1 to 2% of the total body magnesium content in blood plasma and red blood cells. Magnesium in the body may be bound either to proteins or "anions" (negatively charged substances). About 55% of the body’s magnesium content is in the "ionic" form, which means that it carries an electrical charge. Magnesium ions are "cations," ions that carry a positive charge. In its charged state, magnesium functions as one of the mineral "electrolytes."*
Magnesium works as a co-factor for over 300 enzymatic reactions in the body. Metabolism uses a phosphate-containing molecule called ATP as its energy source. Magnesium is required for all reactions involving ATP. ATP supplies the energy for physical activity, by releasing energy stored in "phosphate bonds".*
Skeletal and heart muscles use up large amounts of ATP. The energy for muscle contraction is released when one of ATP’s phosphate bonds is broken, in a reaction that produces ADP. Phosphate is added back to ADP, re-forming ATP. ATP also powers the cellular "calcium pump" which allows muscle cells to relax. Because it participates in these ATP-controlled processes, magnesium is vitally important for muscle contraction and relaxation. By controlling the flow of sodium, potassium and calcium in and out of cells, magnesium regulates the function of nerves as well as muscles.*
Magnesium’s importance for heart health is widely recognized. The heart is the only muscle in the body that generates its own electrical impulses. Through its influence on the heart’s electrical conduction system, magnesium is essential for maintenance of a smooth, regular heartbeat. Magnesium appears to help the heart resist the effects of systemic stress. Magnesium deficiency aggravates cardiac damage due to acute systemic stress (such as caused by infection or trauma), while magnesium supplementation protects the heart against stress. This has been found true even in the absence of an actual magnesium deficit in the body.*
Evidence suggests that magnesium may help support mineral bone density in elderly women. In a two-year, open, controlled trial, 22 out of a group of 31 postmenopausal women who took daily magnesium supplements showed gains in bone density. A control group of 23 women who declined taking the supplements had decreases in bone density. The dietary intakes of magnesium, potassium, fruit and vegetables are associated with increased bone density in elderly women and men. In an interesting animal study, rats were fed diets with either high or low levels of magnesium. Compared to the high magnesium-fed rats, bone strength and magnesium content of bone decreased in the low-magnesium rats, even though these rats showed no visible signs of magnesium deficiency. While this finding may or may not apply to humans, it raises the possibility that diets supplying low magnesium intakes may contribute to weakening of bone in the elderly.*
Maximizing Absorption––Chelated Minerals Explained Mineral absorption occurs mainly in the small intestine. Like any mineral, magnesium may be absorbed as an "ion," a mineral in its elemental state that carries an electric charge. Mineral ions cross the intestinal membrane either through "active transport" by a protein carrier imbedded in the cells lining the membrane inner wall, or by simple diffusion. The magnesium in mineral salts is absorbed in ionic form. However, absorption of ionic minerals can be compromised by any number of factors, including: 1) Low solubility of the starting salt, which inhibits release of the mineral ion, and 2) Binding of the released ion to naturally occurring dietary factors such as phytates, fats and other minerals that form indigestible mineral complexes.*
A second absorption mechanism has been discovered for minerals. Experiments have shown that minerals chemically bonded to amino acids (building blocks of protein) are absorbed differently from mineral ions. This has given rise to the introduction of "chelated" minerals as dietary supplements. Mineral amino acid chelates consist of a single atom of elemental mineral that is surrounded by two or more amino acid molecules in a stable, ring-like structure.*
Unlike mineral salts, which must be digested by stomach acid before the desired mineral portion can be released and absorbed, mineral chelates are not broken down in the stomach or intestines. Instead, chelates cross the intestinal wall intact, carrying the mineral tightly bound and hidden within the amino acid ring. The mineral is then released into the bloodstream for use by the body.
Research by pioneers in the field of mineralchelation and human nutrition indicates that the best-absorbed chelates consist of one mineral atom chelated with two amino acids. This form of chelate is called a "di-peptide." Compared to other chelates, di-peptides have the ideal chemical attributes for optimum absorption. Dipeptide chelates demonstrate superior absorption compared to mineral salts. For example, a magnesium di-peptide chelate was shown to be four times better absorbed than magnesium oxide.*
Consumer Alert! Not all "amino acid chelates" are true chelates. In order for a mineral supplement to qualify as a genuine chelate, it must be carefully processed to ensure that the mineral is chemically bonded to the amino acids in a stable molecule with the right characteristics. The magnesium bis-glycinate/lysinate in High Absorption Magnesium is a genuine di-peptide chelate ("bis" means "two"). It has a molecular weight of 324 daltons, considerably lower than the upper limit of 800 daltons stated in the definition of "mineral amino acid chelates" adopted by the National Nutritional Foods Association in 1996.*
Bioperine For Enhanced Absorption Bioperine is a natural extract derived from black pepper that increases nutrient absorption. Preliminary trials on humans have shown significant increases in the absorption of nutrients consumed along with Bioperine.*

Q. What are Chelates? A. If you know the importance of chelated mineral supplements, there's something else you should know. Not all supplements claiming to contain "amino acid chelates" are, in fact, genuinely chelated. Some are simply mineral salts mixed with vegetable protein. Genuine chelates are made with a special process that creates a true bond between a mineral and an amino acid. This is why Doctor's Best has chosen Albion Laboratories' chelated minerals. Long-established as the leading chelated mineral manufacturer, Albion chelates provide optimum absorption. Our High Absorption Calcium bears Albion's Gold Medallion, signifying that it contains genuine amino acid chelated minerals. When chelated magnesium is combined with an amino acid, it is much easier for it to cross the intestinal wall and enter the bloodstream, because amino acids have their own, much wider entryways.* Magnesium, the fourth most abundant mineral in the body, helps maintain a healthy heartbeat, allows muscles to relax and helps cells produce metabolic energy. High Absorption Magnesium contains 100% fully-reacted chelates of magnesium with the amino acids glycine & lysine.* So, High Absorption Magnesium is really a mineral and an amino acid supplement. Glycine and lysine are both highly beneficial nutrients: Glycine benefits the nerves, supports collagen formation, and helps build strong nails. Lysine is an essential amino acid that supports digestion.* High Absorption Magnesium is enhanced with Bioperine, a patented extract of black pepper fruit that boosts nutrient absorption. Clinical studies demonstrate increased absorption of nutrients taken along with Bioperine.* Q. What is the source of Magnesium? A. The magnesium found in High Absorption Magnesium originally comes from magnesium oxide. Elemental magnesium is separated out of the magnesium oxide and chelated with the amino acids lysine and glycine. There are no leftover residues of the magnesium oxide in the finished product. It is 100% chelated magnesium lysinate-glycinate.Q. What is the croscarmellose sodium excipient that is found in the High Absorption Magnesium? A. Croscarmellose sodium is a commonly used excipient in tablets. It is widely used in the pharmaceutical industry as a "disintegrant," which means that it helps tablets break apart in the stomach. In simple terms, croscarmellose sodium is made of cellulose gum with a very small amount of sodium. The sodium content is less than a half a percent (less than 0.5%). Technically speaking, croscarmellose sodium is a cross-linked polymer of carboxymethylcellulose sodium. Croscarmellose sodium is recognized as being essentially non-toxic and non-irritating. Cellulose is a non-digestible fiber, which means the tiny amount in tablets passes through the gut without being broken down or absorbed. As far as adding to anyone's dietary sodium intake, the amount is too small to be of any consequence.*Q. How can you tell whether the Magnesium is being absorbed? A. One way to tell is that magnesium tends to relax muscles and make it easier to fall asleep. Absorption has to do with getting the substance from the stomach into the blood stream. If the tablets appear in the stool, it means they are not breaking down and not being absorbed, which are not the same thing. One of the virtues of HAM is that it is very well absorbed. Most forms of magnesium are not very well absorbed (think of "Milk of Magnesia"). The result of poor absorption is that the intestines get irritated and, in an attempt to get rid of the irritation quickly, the intestinal muscles vigorously contract and force the contents through more quickly (i.e. diarrhea). Q. Are there any side effects to the HAM? A. Everything, including water, can have unwanted side effects. Taking, and absorbing, too much HAM could cause diarrhea, or could make a person feel like their muscles have gone weak.Q. How much "elemental" magnesium is in each tablet of HAM? A. There is 100 mg elemental magnesium, which is chelated (bound) to 900 mg of "magnesium bis-glycinate/lysinate." This product has a much higher level of absorption and cellular utilization than non-chelated forms of magnesium.

Q. What are your capsules made of? A. Doctor's Best capsules are typical gelatin capsules, with the exception of select products now available in veggie cap form. They are made of gelatin from cattle, like the familiar "Knox gelatin" sold in grocery stores. The gelatin used to make Doctor's Best's capsules is manufactured in accordance with strict guidelines that ensure it is BSE-free.The FDA and the supplement industry approved these guidelines. The gelatin is made only from cattle living in non-BSE countries. All Doctor's Best capsules are in full compliance with the FDA's September 1997 industry guide, The Sourcing and Processing of Gelatin to Reduce the Potential Risk Posed by Bovine Spongiform Encephalopathy in FDA-Regulated Products for Human Use . Q. How long does it take for a capsule to dissolve? A. Approximately 30-45 minutes. For 2-piece gelatin capsule, the USP standard for maximum dissolution time is 45 minutes. Q. How long does it take for a tablet to dissolve? A. FDA Rules & Regulations require tablets to dissolve in 45 minutes or less. However, Doctor's Best sets its standards higher. They require that their tablets dissolve in 30 minutes or less. Every lot of products in tablet form is tested to verify that it dissolves in under 30 minutes. Q. Can I find out how fast a capsule or tablet dissolves by dropping it in a glass of water or vinegar at home? A. Testing dissolution times at home using vinegar is not an accurate way to learn what happens to capsules and tablets in your stomach. Because stomach acid is much stronger than vinegar, capsules and tablets dissolve much faster in the stomach than in a glass of water or vinegar. Also, the stomach continually "agitates" its contents, much like a washing machine does.
Q. Who determines what the daily dosage should be? And how is this done? A. A panel of scientists at The Natural Academy of Sciences performs extensive research, ongoing clinical studies and scientific testing in order to determine the RDI (Recommended Daily Intake). Q. I see that Silicon Dioxide has been used as an excipient in some of your products. Should I be concerned? A. Silicon Dioxide is a GRAS (Generally Recognized As Safe) food additive. Numerous studies have found the following: The oral toxicity for humans would be greater than 350 grams in one dose based on allometric comparisons between the mice studied and humans. A single dose of 2,500mg of amorphous polymeric silicon dioxide to human volunteers did not significantly raise the SiO2 excretion in the urine. This suggests poor absorption of silicon dioxide (Langendorf 1966). Less than one one-hundredth (1/100th) of the dose was found in urine, suggesting extremely poor absorption (Langendorf 1966). This would suggest that there is no scientific reason to eliminate silicon dioxide as an excipient at the very low levels found in dietary supplements. Q. Why is silicon dioxide used as an excipient in Doctor’s Best products? Why are excipients used at all? A. Silicon Dioxide is used as a flow agent to enable "sticky" substances to flow through the encapsulation equipment. If silicon dioxide were not used, other flow agents would have to be used which would actually increase the number of excipients found in a given product. Ideally, the fewer excipients used, the better. Q. Is there a limit to how many vitamins can be taken safely in one day? A. Our bodies need vitamins and minerals, and if taken in large amounts, vitamins and minerals can adversely affect health. Large amounts of anything can be toxic. Our best advice is to work with a nutritionally aware doctor and follow label directions.
