Biotin, also called Vitamin H or Vitamin B7. Biotin is a water-soluble B-Complex Vitamin that is needed for the metabolism of fats, carbohydrates and proteins.

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.

Chromium.

Copper is a naturally occurring mineral in foods like shell fish, vegetables, avocado fruits, legumes, grains, nuts, and beef. As copper originates from the earth's crust, the surface water and ground water contains small traces of copper. Copper is implicated in many biochemical reactions within the human cells.

Folic Acid or Vitamin B9 is essential as it assists the formation of red blood cells in the body and genetic material within every cell. It helps in metabolism of proteins and prevention of anemia and is vital for cell growth and division. Folic acid is an important nutrient for pregnant women to prevent congenital malformation in the fetus. It reduces the risk of brain and spinal cord defects, heart defects, limb defects, urinary tract abnormalities and cleft palate in the fetus. It is highly beneficial if taken prior to and during the first month after conception. In men, folic acid reduces chromosomal defects in the sperm. Spinach, lettuce, peas, beans, sunflower seeds, asparagus, baker’s yeast, fortified cereal products and liver are rich in folic acid.

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 vital in human nutrition as the adult human body contains 3-4 grams of iron. Haem-iron and non-haem iron are the two types of iron. Foods rich in haem-iron include meat, liver, fish, and poultry. Foods that are high in non-haem iron are those of vegetable origin, like green leafy vegetables, cereals, legumes, oilseeds, nuts, dry fruits and jiggery. Iron is vital for numerous body functions, including hemoglobin formation, brain development and function, muscle activity, regulation of body temperature and catecholamine. Deficiency of iron affects immune system, reduces the number of T-cells and production of antibodies. Iron is also necessary for binding oxygen to body cells as its main function is oxygen transport and cell respiration. It works as an anti-cancer agent. Iron increases energy level of the body, improving physical performance. It prevents insomnia.

Magnesium, which is a mineral used by the body to help maintain muscles, bones, and nerves. Magnesium is also needed for energy metabolism and protein synthesis.

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, commonly called vitamin B5, is water soluble and is needed by every cell in the body to maintain good health. It helps in breaking down carbohydrates, fats and proteins to provide the body with energy. It assists in the production of red blood cells and hormones and ensures a healthy pregnancy. It is also known to lower triglyceride and cholesterol levels in the body. It helps in reducing stress and treating people with rheumatoid arthritis. Pantothenic acid is found in small quantities in almost all foods but abundantly in meats, fish, poultry, avocados, peas, broccoli and whole grains. A deficiency which is rare, leads to leg cramps, gastrointestinal problems, anemia, insomnia, depression, a burning sensation in the limbs and a weakened immune system.

Phosphate (Phosphorus) is perhaps one of the most important mineral, which in form of phosphate as an intercellular anion serves a multitude of functions. Not only are phosphates essential for the utilization of most vitamins belonging to the B complex, but they are vital for energy storage and the overall metabolism. But that is not all, phosphate is essential for healthy bones and teeth, calcium with phosphorus are required for them and soft tissues as well. But also body fluids require phosphates for excretion of hydrogen ions through the kidneys. Somewhere around one per cent of the body weight should be phosphorus in some form, therefore it is vital to supply your body with sufficient phosphates through milk, cheese, nuts, peanut butter, peas and other sources, including supplements.

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 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 E is an antioxidant that is known for protecting the tissues of the body from damage caused by free radicals.

Vitamin K- The lipophillic, hydrophobic vitamins needed for the posttranslational modification of certain proteins is denoted by the Vitamin K. It is required mostly for blood coagulation. K3, K4 and K5 are the three types of synthetic Vitamin K that are used in many areas. Pet food industry makes use of Vitamin K3 whereas Vitmanin K5 is used to inhibit fungal growth. The main sources of vitamin K are spinach, cauliflower, broccoli, cabbage and a few fruits like kiwifruit and avocado. Recent research shows that vitamin K helps in increasing bone mass. Research also shows that the consumption of vitamin K helps in promoting osteotrophic processes while at the same time slowing the osteoclastic processes. This process is done by achieving the calcium bonding in the bones.

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.
