Biotin is essential to cellular metabolism, as it plays an important coenzyme role in the metabolism of fats, carbohydrates and proteins.

Calcium, a mineral vital to the human body, Calcium is necessary for many bodily functions, such as muscle contraction, and proper heart function.

Chromium.

Copper, a trace element that is essential for the human body. Copper is needed to absorb and utilize iron in the body. Copper is a part of enzymes, essentially proteins that assist biochemical reactions in cells.

Folic Acid produces healthy red blood cells and prevents anemia in both children and adults. It is especially important in pregnancy and infancy and is also believed to help in the prevention of cancer, stroke and heart disease.

Iodine, a necessary element used by the body to make the thyroid hormones thyroxine and triiodothyronine. These Thyroid hormones are needed to maintain a healthy metabolic rate and cellular metabolism.

Iron is one of the most commonly available chemical elements which are used in the form of metal. When in the presence of oxygen and moisture, iron gets oxidized very easily. Therefore it is never available on the surface of earth. Iron is a metal whose properties can be changed by mixing it with the various other metals. Humans need iron as a daily dietary substance. There are a number of supplements available in market which provides the daily required dose of iron. But the best way to consume iron is by eating the food that is rich in iron. Fish, poultry, beans, lentils, leafy vegetables are some of food items that are a good source of iron. Although, research shows that it is easier to digest the iron found in meat and meat products than the vegetables.

Magnesium is another mineral which is deemed essential for all biological life. As an essential part of basic nucleic acid, magnesium ions, together with phosphate ions, are also required for over 300 catalytic reactions of enzymes. Any enzymes synthesizing or utilizing adenosine triphosphate require a magnesium ion. Incredulously enough, magnesium deficiency is the most widespread deficiency, affecting a third of the population in the United States only, with third world countries surpassing the count easily. Being also essential, together with calcium and phosphorus, in the skeletal structure, magnesium deficiency is viewed as a main factor in ailments such as osteoporosis. Naturally available through cereals, green leafy vegetables, nuts, spices, tea, cocoa and coffee, magnesium is available as a supplement in magnesium oxide and magnesium citrate form, whereby the latter is viewed as more bioavailable.

Manganese is a mineral that is required in small amounts to manufacture enzymes necessary for the metabolism of proteins and fat. It also aids the immune system and blood sugar balance. Manganese is also involved in the production of cellular energy, reproduction and bone growth.

Molybdenum is essential in regulating pH balance in the body, enhancing the body’s ability to burn fat. Very small amounts are needed. Molybdenum is necessary for the proper function of certain enzyme-dependent processes, including the metabolism of iron. Molybdenum also promotes normal cell function and helps in the activation of certain enzymes, it is a key component of the metabolic enzyme xanthine oxidase. Molybdenum is found in the liver, bones and kidneys. It supports bone growth and teeth strength. A deficiency may cause impotence in older men. High intakes of sulfur and diets high in refined and processed foods may decrease molybdenum levels.There is no recommended dietary allowance for molybdenum.

Niacin is a vitamin that wards against pellagra, a disease characterized by a vitamin B3 deficiency. Niacin is made from pyridine and is often called vitamin B3 or nicotinamide, because they all three have similar formulas. Niacin and nicotinamide are comparable in make up, but only niacin works to lower cholesterol levels. The restoration of DNA is also known to be a positive side effect of taking niacin. A fairly large number of individuals, particularly those in third world countries or those suffering from alcoholism, have been shown to be lacking in niacin. Niacin is often taken as a supplement by those with high cholesterol levels, as it has been proven to lower “bad” cholesterol and raise “good” cholesterol.

Pantothenic Acid also known as B5 is a natural, inexpensive and safe form of curing acne. It is free from all negative side effects. It is best suited for people with oily skin as it stops the overproduction of oil within our body. It converts the carbohydrates and fats into energy effectively when synthesized with other Vitamin B. Additionally it also helps your body produce red blood cells and metabolizes fats. It plays a significant role in reducing physical and mental stress because it works along with the stress hormone producing adrenal gland. Pantothenic acid is present in all kinds of food and therefore our body gets sufficient amount of it. As it is impossible for our body to become deficient in pantothenic acid, there is no recommended daily amount of it. Eggs, whole grains and milk contain panthothenic acid in large numbers.

Phosphate (Phosphorus) is the chemical element with the atomic number 15 in the periodic table. It is not found as a free element anywhere in the world. In biology and biochemistry it may be the most important element, being present in all living cells of living species. It is present in the DNA, in the RNA, in ATP, but is also found in cell membranes in form of phospholipids. It is also present in the bones, where it builds calcium phosphate salts, responsible for strong bones. Apatite is a collection of phosphate minerals which are generally found in bones and teeth; namely bromapatite, fluorapatite, chlorapatite and hydroxyapatite. Several phosphates are being added to body building supplements and powders, intended to aid in skeletal and cellular strength improvement.

Potassium is an electrolyte, a substance that maintains the fluid levels in the body. It is helpful in regulating blood pressure and heart function. Intake of potassium can benefit people suffering from hypertension. Research has found that a potassium supplement intake decreased incidence of stroke by 60 percent. It neutralizes acids and restores alkaline salts to bloodstream.  It acts along with sodium cells to maintain or restore membrane potentials. Potassium is also vital for nerve functioning and cardiovascular, and regulates nutrients’ transfer into cells and adds to muscle energy. It also helps recuperative powers, besides regulating water balance. Potassium is beneficial for eliminating wastes. It is helpful in controlling headaches and convulsions, and quickens healing of cuts, bruises and other injuries.

Riboflavin, also called Vitamin B2, is naturally manufactured by the body. Riboflavin is needed for the proper use of oxygen and amino acids, carbohydrates and fatty acids. Riboflavin is also utilized by Vitamin B6 in the body and is used to manufacture niacin. Riboflavin is especially needed when eating large amounts of protein.

Selenium is considered good for health if taken in small amounts. It is a trace mineral which when incorporated into protein, makes selenoproteins that helps stop cellular damage due to free radicals. The major source of selenium is plant foods and its content in the food depends on the selenium content in the soil where it was grown. Also known as selenium acid, selenium sulfide and selenium yeast, this mineral is available in seafood and meat products. The main function of selenium is to work with vitamin E in order to maintain the elasticity and preservation of tissues. It not only helps in improving the supply of oxygen and blood to the muscles in the heart but also slows down the aging process by enhancing endurance.

Sodium is the element that has the atomic number 11 in the periodic table and is commonly known as the main component in the table salt, together with chloride. Interestingly enough, it is probably the one dietary component which does require limitation rather than supplementation, since that average daily nutritional requirement is around half a gram per day. This most popular food seasoning, salt, is providing the most common source of sodium and chloride in human diets, but is generally overused and may cause health problems, such as high blood pressure, if consumed overly generously. The suggested dose of table salt, or rather the upper limit portion, would be somewhat less than 6 gram per day, according to the Dietary Guidelines for Americans, referenced by FDA. In the UK this limit is set at four grams per day.

Thiamine, also called Vitamin B1 or Thiamin, is needed to help the body utilize energy from proteins, fats and carbohydrates. Thiamine is commonly found in breads and cereals. Thiamine is water-soluble and is concentrated in muscle tissue as it passes thru the body.

Vitamin A is used for improving poor night vision, dry skin, and it can help acne. It is also a fat soluble vitamin. Too much vitamin A can cause side effects. An excess of vitamin A can actually make acne worse.

Vitamin B12, also known as cobalamin, which is naturally found in foods such as fish, milk and milk products, eggs, meat and poultry. Vitamin B12 is important for good health, necessary for the proper digestion and absorption of foods and for normal metabolism of carbohydrates, and fat. It helps maintain healthy nerve cells and red blood cells and is needed to make DNA. Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Unlike other water-soluble nutrients, vitamin B12 is stored in the liver, kidney, and other body tissues. It can take several years before signs of the deficiency appear due to poor dietary intake. Vitamin B12 functions as a "methyl donor." A methyl donor is a compound that carries and donates methyl groups to other molecules, including cell membrane components and neurotransmitters. As a methyl donor vitamin B12 is involved in homocysteine metabolism and plays a critical role in proper energy metabolism, immune function, and nerve function. Therefore, vitamin B12 is clearly an added benefit for anyone wanting to lose weight, as without it, metabolism is not at its peak potential.

Vitamin B6 is important to a healthy human diet and is equally important in various metabolic and synthesis functions as well as gene expression.

Vitamin C is an obvious essential nutrient and a deficiency of this will cause scurvy. It is also an antioxidant and acts as an electron donor for eight different enzymes.

Vitamin D is actually a group of prohormones, all fat soluble, whereby ergocalciferol, or Vitamin D2 and cholecalciferol, also known as Vitamin D3 are the most common forms. The Vitamin D3 form is made when human skin is exposed to UV B radiation. The active form of Vitamin D is calcitrol and it is required in the body to manage phosphorus and calcium levels, but, among other functions, to affect anti tumor activity, immunomodulatory functions and much more. Vitamin D, or more accurately calcitrol, is being bound to a carrier protein, which allows it to be transported throughout the body to the various destinations. The Vitamin D receptors, steroid and thyroid hormone receptors, can be found in most organs, including the brain, skin, heart, breast, prostate and gonads.

Vitamin E, an anti-oxidant nutrient, neutralizes free radicals in the human body to prevent cell damage. This fat-soluble vitamin not only aids the formation of red blood cells but also helps in the absorption of vitamins A, C and K. It is also very helpful to fight various ailments. Since the human body cannot produce vitamin E on its own; it has to be incorporated in our daily diet. This can be done either by consuming foods that are rich in vitamin E or by taking vitamin E supplements. The RDA for adult males is 10 mg. while 8 mg. is the daily requirement for adult females. Expecting and nursing women should compulsorily take 10 mg. of vitamin E supplements. Vitamin E supplements are most effective when consumed with food.

Zinc is acknowledged as essential to the human organism. It is a trace element found in over a hundred and up to three hundred enzymes. It is the second most important mineral in the body, after iron. Zinc is also defined as an important catalytic agent, which is active in enzymatic reactions such as hydroxilation, which is essential for the protein forming amino acid proline, but also for hypoxia response. Zinc is naturally found in red meat, milk, spinach, nuts, oysters, beans and oats. Low zinc counts can attribute to a weakened immune system, interfere with muscle building, cause diarrhea and all kind of other deficiencies. In body building circles, Zinc is an important supplement, valued for the indirect increment of testosterone and the muscle building role.
