Biotin is required for the fatty acids and glucose formation so that essential energy is produced. Biotin also assists in the metabolism of fats, proteins and carbohydrates. Biotin is available in food naturally and the dietary sources of biotin comprise of brewer’s yeast, cauliflower, bananas, egg yolks, salmon, liver, sardines, mushrooms and legumes. The deficiency of biotin is uncommon. The other possibilities for having biotin as deficiency is genetic biotin deficiency, surgical stomach removal, excessive consumption of alcohol and infant dermatitis. Biotin deficiency leads to hair loss, skin rash, heart problems and high cholesterol. Biotin supplements are effective for eczema, acne, diaper rash, brittle nails and hair loss. People having a history of seizures should avoid using biotin. This is a B vitamin that helps in converting food to energy. It is mandatory that minimum 30 mg is taken daily as there are adequate health benefits. Normal biotin intake strengthens fingernails and also controls blood sugar levels.

Calcium, is a supple gray alkaline earth metal, which is the fifth most abundant element by mass in the Earth's crust. Calcium is also at the fifth most profuse dissolved ion in seawater by both molarities and mass. Calcium is a significant nutrient that we require in our bodies. It has many imperative functions. It helps getting strong teeth and bones and is involved in muscle contractions and blood clotting, The calcium is mainly stored in our teeth and bones. Low calcium level may lead to the bone fractures and in some cases porous bones or osteoporosis, generally in old age. The intake of calcium can drop down the high blood pressure, maintain your heart functions, avert gum disease, prevent colon and rectum cancer, and help blood to clot.

Choline, sometimes called Choline Bitartrate, is an essential nutrient involved in many bodily actions such as the structure and function of cells and metabolic functions.

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 is an essential water soluble vitamin. Though folic acid is needed for all age groups, folic acid supplements is necessary for aging people, pregnant women, smokers, women on oral contraceptives and heavy alcohol drinkers as their body have difficulty in absorbing folic acid through food. Folic acid has many vital functions to perform in our body. It helps in preventing heart disease, stroke, and may help prevent cervical, lung and colon cancer and helps in maturation of red blood cells. It’s recommended that pregnant women take folic acid supplementation through out pregnancy as it helps prevent premature delivery, low birth weight and fetal growth retardation. It may also help reduce the risk of renal disease in children and is necessary for fertility in both women and men. Some studies suggest that there is a relationship between folic acid and allergic diseases and depression. It also reduces risk of bone fractures, osteoporosis and helps prevent rheumatoid arthritis. It increases lipolysis and may help in preventing obesity and type 2 diabetes. In a study conducted it increased the short-term memory, mental agility and verbal fluency of people who consumed folic acid supplements (800mgs) daily. Folic acid supplements are also used to relieve hot flushes in postmenopausal women and helps correct anemia caused by vitamin B 12 deficiencies.

Inositol - The precise role of Inositol is unknown. Animals deficient in inositol grow poorly and show hair loss. iI occurs naturally in fruits and cereals.

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 a necessary mineral for humans, needed for example to help form red blood cells which transport oxygen around the body. Fortunately there are plenty of good sources available for both the omnivore and the vegetarian or vegan These include liver, meat, beans, nuts, dried fruit , also whole grains and many of dark green leafy vegetables, although some such as spinach also contain substances that prevent the absorption of iron as do caffeine based drinks such as tea and coffee. On the other hand the drinking of fluids containing vitamin C aids the body in its necessary task of absorbing iron.

Lecithin is needed by every cell in the body and is a key building block of cell membranes; without it, they would harden. Lecithin protects cells from oxidation and largely comprises the protective sheaths surrounding the brain. It is composed mostly of B vitamins, phosphoric acid, choline, linoleic acid and inositol. Although it is a fatty substance, it is also a fat emulsifier.

Magnesium is a mineral that may be found inside most of the cells in the body tissues and organs. It is important in the absorption of calcium and aids in the formation and development of bones and teeth. Magnesium deficient individuals have an increased risk of acquiring osteoporosis; they also have problematic menstrual cycle such as premenstrual syndrome, irregular cycle and dysmenorrhoea. Magnesium helps in maintaining the cardiovascular health and decreases the risk of heart problems. It also prevents gallstones from forming. Magnesium is useful in the treatment of high blood pressure. It is also helpful in treating erectile dysfunction and prostate problems.

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.

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.

PABA is an important growth factor for many micro-organisms and a deficiency causes a loss of hair color in mice. No vitamin function has been shown in humans.

Pantothenic Acid, commonly called Vitamin B5, it is a water-soluble member of the vitamin B complex. Pantothenic acid is involved in adrenal gland function and is required to fight stress.

Phosphate (Phosphorus) is a chemical element that is found in the periodic table with the atomic number fifteen. As a high reactive element, it is not found in clean form as a free element in nature. It is one of the most important and essential elements in the human body, being found in phospholipids that form all the membranes of cells, the DNA, the RNA and also the ATP. Cellular energy is being transported by phosphate in form of adenosine triphosphate, calcium phosphate, which are salts, are responsible for the stiffness of bones. In the average human, the amount of phosphorus in weight would be about one kilogram, whereby most of it is in form of apatite and found in teeth and bones. The daily consumption of phosphorus through dietary means is estimated at about one to three grams.

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 a chemical element and a trace mineral deemed essential to human nutrition. It is found in many food sources, like beef liver, turkey, chicken breast, roast beef, white bread, whole eggs, rice, oatmeal, pasta, Brazil nuts, tuna and many others. Just recently a correlation between selenium, Vitamin E and cancer prevention has been scientifically proven. This essential trace element nutrient is nevertheless toxic in excessive doses, but is vital as a cofactor where antioxidant enzyme glutathione peroxidase is required. Besides the belief that selenium may have a role in prevention from cancer, it has been observed that population in HIV and AIDS stricken countries where the soil is deficient in selenium have larger outbreaks than areas where selenium is sufficiently present. Other uses, such as in prevention from recurrence of tuberculosis, have been recommended by researchers.

Thiamine is a water-soluble vitamin with no known toxic effects if taken with other members of the vitamin B complex. Thiamine is essential to a strong appetite and to enable the body to use sugars and other carbohydrates.

Vitamin A- Otherwise known as retinol is the vitamin which helps the eyes to adjust to changes in light levels as well as keeping the eyes, skin and mucous membranes moist. Vitamin A enters the human diet mostly from animal foods, but as well as this some plant foods contain beta-carotene, which the body is then able to convert into Vitamin A. Retinol has antioxidant properties that help the body to repair tissue and cellular damage by neutralizing free radicals. Although there seems to be some evidence that retinol may help in cases of established artery disease the American Heart Association does not recommend it as a necessary supplement until there is more evidence.

Vitamin B12 is a potent vitamin that needs only a little amount of dosage to work efficiently. It is sometime referred to as “cobalamin” because of its cobalt contents. It plays an important role in the production of protein from amino acids, maintenance of nervous system, growth and development, and in the production of deoxyribonucleic acid (DNA). It helps prevent anemia because it promotes the production and formation of healthy red blood cells. It also protects the myelin in the nervous system that enables them to function properly that promotes mental clarity, and prevent memory loss. It is also important in cell replication, and proper metabolism of energy.

Vitamin B6 is a water-soluble member of the vitamin B complex. It exists in thre forms and often occurs in nature as a mixture of these three forms. Vitamin B6 is involved in protein, fat, and sugar metabolism.

Vitamin C is L-ascorbic acid, or the active component of Vitamin C. Ascorbate, which is an ion of the ascorbic acid, is required for many metabolic reactions and is manufactured internally by most organisms, except humans. It is an essential nutrient and needs to be provided through nutrition. While oranges were traditionally deemed a good source of Vitamin C, the amount provided by an orange is dwarfed by the amount provided by the kakadu plum the richest Vitamin C plant resource of the world. Other notable sources are red peppers, parsley, Kiwifruit, Guava, Broccoli, Camu Camu, rose hip, Jujube, papaya, strawberries, lemon, melon and similar. Vitamin C is essential for tyrosine, carnitine and collagen synthesis, is the most widely available antioxidant and furthermore is vital for blood vessels, cartilage and scar tissue.

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.
