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.

Chromium is a natural trace mineral in human nutrition and is needed for proper metabolism of sugar in humans. It is vital for metabolism of fats and carbohydrates. It helps move blood sugar from the bloodstream into cells to be utilized as energy and turn fats, carbohydrates, and proteins into energy. Chromium helps stimulate fatty acid and cholesterol synthesis, which are needed for brain function and other body processes. It activates numerous enzymes that are required to drive many chemical reactions essential to life. Chromium supplements also improve glucose tolerance in people with Turner's syndrome, a disease associated with glucose intolerance. It is also vital for insulin metabolism. It regulates hunger and decreases cravings.

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, 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.

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, 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 also known as B5 is a natural, inexpensive and safe form of curing acne. It is free from all negative side effects. It is best suited for people with oily skin as it stops the overproduction of oil within our body. It converts the carbohydrates and fats into energy effectively when synthesized with other Vitamin B. Additionally it also helps your body produce red blood cells and metabolizes fats. It plays a significant role in reducing physical and mental stress because it works along with the stress hormone producing adrenal gland. Pantothenic acid is present in all kinds of food and therefore our body gets sufficient amount of it. As it is impossible for our body to become deficient in pantothenic acid, there is no recommended daily amount of it. Eggs, whole grains and milk contain panthothenic acid in large numbers.

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 , an essential mineral that is toxic at high dosages. Selenium plays an important function in the antioxidant enzymes that protect cells against free radicals. Selenium also promotes proper thyroid hormone metabolism.

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 needed by the retina of the eye in the form of a specific metabolite(the light-absorbing molecule retinal). This molecule is absolutely necessary for both scotopic and color vision. It also palys an important role in the health or our skin, bone metabolism, immune function. It is also commercially produced and administered as esters such as retinyl acetate commonly called Vitamin A acetate. Its defeciency can cause blindness. Other problems include impaired immunity, hypokeratosis (white lumps at hair follicles), keratosis pilaris and squamous metaplasia of the epithelium lining the upper respiratory passages and urinary bladder to a keratinized epithelium.

Vitamin B12 is a water soluble vitamin that is also referred to as cobalamin. It plays an important role in the function of the brain, the nervous system, and in the formation of the blood. It helps prevent pernicious anemia that results in chronic fatigue, breathlessness, listlessness, pallor and susceptibility to infection. It also alleviates premenstrual syndrome (PMS) and prevents other such menstrual disorders. Vitamin B12 also improves memory retention, focus, and concentration. It helps prevent the degeneration of nerves and irreversible neurological damages that may lead to serious illnesses such as Alzheimer’s disease. It is important for the maintenance of healthy nervous system.

Vitamin B6- There are three traditionally considered forms of vitamin B6: pyridoxal (PL), pyridoxine (PN), pyridoxamine (PM). The phosphate ester (PLP) has a leading role in metabolism of human body. It is obtained from the diet since humans cannot manufacture it. PLP is crucial in over 100 enzymes that enable important chemical reactions in the human body. In the brain, the manufacture of neurotransmitters like serotonin from tryptophan is made possible by PLP. PLP is also a coenzyme in the production of the iron coating component of hemoglobin called heme. Signs of vitamin B6 deficiency include irritability, depression and confusion, inflammation of the tongue, sores or ulcers of the mouth and the skin at the corner of the mouth.

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 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 a mineral found in most cells in the human body. It plays an important role in stimulating enzyme functions. It improves the immune system that protects against bacterial and viral infections. It also promotes healing of wound. Zinc helps in maintaining a normal growth and development during pregnancy, childhood and adolescence. It also has antioxidant properties that prevent cell damage caused by free radicals that may lead to premature aging, heart problems and even cancer. It aids in cell growth, renewal, and repair. Zinc increases muscle growth and improves endurance. It also helps cleanse and get rid of toxins that accumulated in the body.
