The ideal method of getting necessary vitamins and minerals is through natural foods and juices. In most cases the modern diet does not provide all of the key nutrients needed for healthy living, so many people turn to vitamins and supplements. The effectiveness of these additions are often dependent on when they are taken and whether they are taken with or without food. Key Takeaways:

Copper is an essential trace mineral necessary for life, and it is necessary for the proper function of certain enzymes that allow certain biochemical functions of the body to take place. Without copper neither plant nor animal life would be possible. Dietary sources include nuts, grains, seeds, beans and other vegetable protein sources. Although it is also obtained from animal sources, these tend to be rich in zinc, and for reasons that will be discussed shortly, the presence of zinc can deplete copper absorption. Other common sources are copper cooking utensils and drinking water from copper pipes. After digestion, copper is absorbed into the body through the stomach and the small intestine. It is also possible for copper to be absorbed through the skin from copper bracelets. Once absorbed, copper is bound to albumin and taken by the blood to the liver, where it is bound to a plasma protein known as ceruloplasmin. Among the enzymes with which copper is associated as a ‘helper’ are Cytochrome C oxidase, used in the conversion of glucose to energy, Dopamine hydroxylase, an essential component in the biochemical production of adrenaline, and superoxidase dismutase, that protects against the oxidative damage of cell tissue. Of particular benefit are its anti-inflammatory and antioxidant properties, and its role in energy production. Because of its antioxidant effect, copper could well play a very important role in protecting against atherosclerosis, and cardiovascular disease, the ravaging effects of free radicals on body cells and also certain forms of cancer. Copper is also important in electron transport, and is responsible for the blue coloration of the blood of most molluscs and many arthropods. This is because rather than hemoglobin, these animals use the copper-based hemocyanin for oxygen transport in the blood. Rather than the iron-containing hemoglobin making the blood of these creatures red as it is with mammals, theirs is blue due to the hemocyanin. Copper salts are generally green and blue, as are the blue copper proteins plastocyanin and azurin. So how is copper used by the body? It is, after all, fairly toxic, as little as 30 grams being fatal to humans, bringing on similar symptoms to those of arsenic poisoning. It is in fact the reason for its toxicity that also renders it so useful to the body. The toxicity is largely due to the ability of copper to accept and donate electrons as it changes between oxidation states. This results in the generation of very reactive radicals that can cause severe oxidative stress. The complete reason for its toxicity has yet to be determined, but the stress caused to body cells by free radical oxidation is a very serious condition. It is this rapid change in its oxidation state that is valuable to the enzymes with which it is associated. The ceruloplasmin is responsible for most of the transport of bivalent copper around the body, in the tissues of which it helps to form the bivalent copper enzymes previously mentioned, such as Cytochrome C oxidase and Lysyl oxidase. In doing so the copper is converted to the monovalent state. It also helps to aid in the production of the strong antioxidant Superoxide dismutase (SOD). What this enzyme does is to catalyze the formation of oxygen and hydrogen peroxide by the dismutation of superoxide, a negative ion consisting of two oxygen atoms and a free electron, and hence a very powerful free radical. Dismutation is the simultaneous oxidation and reduction of the species, rendering the free radical relatively harmless. This type of action on free radicals is a very powerful one, and essential in the body’s fight against such free radical species that are so dangerous to animal cells. SOD exists in more than one form, and can also contain zinc, manganese and nickel in addition to copper. The internal fluid (cytosol) of practically all eukaryotic cells (cells containing a nucleus) contain a form of Superoxide dismutase dependent on copper and zinc, while most mitochondria contain an SOD with manganese. Another of the important uses that your body can find for copper lies in the production of hemoglobin. This is because copper is needed for the storage and release of iron to produce hemoglobin, the protein in red blood cells. It is believed that ceruloplasmin is involved in the catalytic formation of ferric iron by the oxidation of Ferrous iron, so allowing the iron to be attached to a protein that transfers it round the body to enable its use in the biosynthesis of various Ferrous compounds, especially of hemoglobin. Copper bracelets are commonly worn by arthritis sufferers, and there is a scientific explanation for that. As previously inferred, it is believed to be possible to absorb copper through the skin and copper is known to be involved in the formation of collagen and is a commonly used treatment for arthritis and osteoporosis. Part of its effect on arthritis is likely due to the antioxidant effect of the SOD that helps to reduce the inflammation at arthritis sites. Although a deficiency in copper can lead to serious health problems, an excess is also harmful. Potential conditions include neurological problems, liver damage and bone abnormalities, although deficiency is far more common because of the competition between copper and zinc. Zinc is a copper antagonist, as is iron and manganese, and copper imbalances can be moderated by the use of these as supplements. The symptoms of a copper deficiency include fatigue, hair loss, stunted growth, anorexia and a host of other conditions. Luckily, however, a deficiency is rare and most people receive a sufficient amount of copper in their diet. Supplements are available to ensure an adequate intake. There is still much to be learned about the interaction between copper and enzymes, and there is also a great deal still to be learned of its role in human metabolism and biochemistry than is currently known. However, sufficient is known already for us to be certain that copper is a very important trace element and that we should be certain that our intake is sufficient, given that zinc iron and manganese compete to prevent copper being absorbed by the body.

Magnesium is a dietary mineral with a wide array of biological activities in the body. 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 requirement for 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 [1]. 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 [2]. 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 [3]. 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 nutrient content of the diets of 7,810 individuals age four and above included magnesium among several nutrients where the amounts supplied by the average diet "were not sufficient to meet recommended standards" [4]. 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 [5]. 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 [6]. 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 [7]. 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 [8]. Women who take both synthetic estrogen and calcium supplements may be at risk for low blood levels of magnesium [9]. 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 [10]. 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, hence is 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 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 [11]. ATP supplies the energy for physical activity, by releasing energy stored in "phosphate bonds". Skeletal and heart muscle 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 [12]. 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 [13]. 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 [14]. 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 [15]. The dietary intakes of magnesium, potassium, fruit and vegetables are associated with increased bone density in elderly women and men [16]. 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 [17]. 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 [18]. 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 mineral chelation 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 [19]. 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 [20]. 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 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 [21]. 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® [22].
