Biotin is essential to cellular metabolism, as it plays an important coenzyme role in 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.

Folic Acid, Folacin or Vitamin B9, as well as the natural Folate, is water soluble and an essential nutrient, necessary, among other reasons, for production of healthy red blood cells and during periods of rapid cell division as well as growth. Folate, the natural form of Vitamin B9, is found in green leafy vegetables, such as spinach and lettuces, but also in liver and liver products. The synthetic form of folic acid is being added to many cereal and bread products, but is also a very popular nutritional supplement ingredient. Pregnant women, but also humans who are involved into rapidly growing muscle tissue, for instance in body building circles, require additional levels of folic acid to the regular nutritional intake. Many multivitamin supplements contain folic acid.

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.

Niacin, also called Vitamin B3, is a water-soluble vitamin needed for the conversion of food into energy so that it may be used by the body. Niacin also helps metabolize protein, sugar and fat.

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.

Riboflavin, an easily absorbed micronutrient, is also known by the name of Vitamin B2. It plays a key role in maintaining the health of animals as well as humans. A wide variety if cellular processes require this vitamin. It plays a key role in energy metabolism, just like other B vitamins. It is the kind of micronutrient which required for the metabolism of proteins, carbohydrates, fats and ketone bodies. There are a lot of food products that are a good source of Vitamin B2. Matured soybeans, yeast, mushroom, livers, kidneys, leafy vegetables, milk, cheese, almonds are such products that are rich in this vitamin. But riboflavin does get destroyed if exposed to light. Riboflavin is a non toxic vitamin. Hence, there is no harm in taking it orally.

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 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.
