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 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.

Folic Acid, a water-soluble B vitamin that is necessary to form essential body proteins. Folic acid, sometimes called Folate also promotes the synthesis of hemoglobin in the body.

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, exists in two main forms, niacin and niacinamide. The niacin form produces a flushing and itching of the skin when taken at higher dosages and this feeling is only temporary.

Pantothenic Acid is thought to reduce lactic acid accumulation in athletes, may improve oxygen utilization efficiency, and is believed to improve the body's ability to heal and possibly help in reducing acne

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, 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 a fat-soluble vitamin with known toxicity. Although its toxicity has been exaggerated, it is a factor worth keeping in mind. Carotine is converted in the human body to Vitamin A, it comes from vegetable sources. Vitamin A is necessary for normal growth and for skeletal development.

Vitamin B12 is a water soluble vitamin and is one of the 8 B vitamins. It has the chemical formula C63H88CoN14O14P. In the absence of Vitamin B12, the brain and the nervous system will not be able to function properly. It also plays a key role in the formation of blood. Vitamin B12 was discovered from its relation to the ailment pernicious anemia. Plants and animals are not capable of synthesizing VitaminB12; the enzymes required for this purpose are found only in bacteria. Vitamin B12 deficiency in human beings is due to its complex human physiology. It is available singly or in combination with other supplements.

Vitamin B6, which active form pyridoxal phosphate or otherwise known as PLP and pyridoxal-5’-phosphate, is a prosthetic group of tightly bound cofactors responsible for many reactions within the amino acid metabolism and the manipulation of the enzymatic reaction behind the release of glucose from glycogen. Vitamin B6 generally comprises three organic compounds, pyridoxine, pyridoxal and pyridoxamine, all of them heterocyclic organic compounds that are converted in the human body to the active pyridoxal phosphate form. There are three reactions attributed to PLP, namely transamination, alpha elimination and beta elimination. Over one hundred and forty enzyme activities depend on pyridoxal phosphate, neurotransmitter and histamine synthesis, synthesis and function of hemoglobin, and gene expression. As a cofactor, PLP is active in amino acid metabolism, glucogenesis and lipid metabolism.

Vitamin C- Perhaps the most popular vitamin, L-ascorbic acid is viewed as an essential nutrient and is required to synthesize collagen in humans. The L-enantiomer of ascorbic acid, or Vitamin C for short, is the famous ingredient of oranges and other citrus fruits. It has been said that a glass of pure squeezed orange juice provides the daily requirement of Vitamin C. While the antioxidant function is deemed important, other biosynthetic functions are of vital significance. It provides an electron for eight different enzymes, besides the aforementioned synthesis of collagen; it aids the synthesis of carnitine and neurotransmitters, synthesis and catabolism of tyrosine and the metabolism of microsome. The additional function as a reducing agent, keeping iron and copper at bay is an additional trait.
