Biotin, also known as vitamin H, but is more commonly called Biotin. It is a vitamin which is B-complex in nature and is water soluble. Biotin helps in transferring carbon dioxide along with helping in various metabolic reactions. A steady blood sugar level can also be maintained by the help of biotin. Hair and nails are strengthened by the consumption of biotin. Therefore, a lot of hair and cosmetic products use biotin as one of its ingredients. The body’s daily requirement of vitamin B7 is produced by the intestinal bacteria. This therefore reduces the chances of vitamin B7 deficiency. There a large number of foods that contain biotin in large quantities. Swiss chard, tomatoes, liver,eggs, almonds, cumcuber, cauliflower, legume, soybeans, raspberries, carrots are some of those foods.

Calcium is a mineral that plays an important role in the development of the human body. It is common knowledge that calcium is important in preventing osteoporosis. However, calcium also provides structural support in the development of muscles. Deficiency in calcium could cause obesity because it triggers the release of parathyroid hormone that stimulates the production of fats in the body and inhibits its breakdown. It also reduces the blood pressure. Calcium also has the ability to fight colon cancer by binding itself with cancer cells to inhibit its growth and progression. It is also beneficial to women suffering from PMS or premenstrual syndrome such as depression, mood swings, anxiety, water retention, breast tenderness, and headaches.

Chromium Picolinate - The popular nutritional supplement, which has been invented to treat chromium deficiency, is also a popular weight loss and muscle growth product. Due to the chromium role it plays in sugar and lipid metabolism in humans, it has been deemed helpful as a supplement, in particular with the body building communities. The argument is that chromium picolinate improves the uptake of glucose by enhancing the effect insulin has in the body, providing better blood circulation. Bad dietary habits, in particular in the United States, have lead to the population verging on the brim of chromium deficiency. Body Building aficionados really require a wholly balanced diet, which in turn requires adequate amounts of chromium be present in the metabolism, even more so if the individual is practicing a serious exercise program.

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.

Vitamin B1, or rather the Vitamin B complex, is a group of vitamins that are all soluble in water and very often coexist in food sources. While every single Vitamin from the B complex group has a name, they are very often referred to by the number added to the Vitamin B group name, like Vitamin B1, which is thiamine, or Vitamin B2, which is riboflavin. Some other compounds have been added to the Vitamin B group at some time, but were later dropped, like adenine, orotic acid or adenosine monophosphate, where later research found that they are either synthesized by the human body or simply no Vitamins. Vitamin B complex supports the metabolism rate, maintains muscle tone and skin, raises functions of the nervous system and the immune system, promotes red blood cells and cell growth and division and much more.

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 B2 is a water-soluble vitamin with no known toxic effects. Riboflavin (Vitamin B2) is necessary in the oxidative process of metabolism. It is also sometimes used to correct certain enzyme deficiencies and improve mental processes.

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.
