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 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.

Magnesium is a mineral that may be found inside most of the cells in the body tissues and organs. It is important in the absorption of calcium and aids in the formation and development of bones and teeth. Magnesium deficient individuals have an increased risk of acquiring osteoporosis; they also have problematic menstrual cycle such as premenstrual syndrome, irregular cycle and dysmenorrhoea. Magnesium helps in maintaining the cardiovascular health and decreases the risk of heart problems. It also prevents gallstones from forming. Magnesium is useful in the treatment of high blood pressure. It is also helpful in treating erectile dysfunction and prostate problems.

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.

Niacin is an essential B vitamin, in cellular energy used for the promotion of healthy cardiovascular function, nervous system function, and immune function. Niacin nutritionally manages cholesterol levels already within the normal range. Also known as vitamin B3, niacin is one of a complex of B vitamins that are essential for good health. Niacin is so-called nicotinic acid, known also as nicotinamide. It helps regulate blood sugar and also works at cellular level protecting the skin and enhances the digestive system. And being an originator of the amino acid tryptophan, it can be made by tryptophan in the body. It’s also a coenzyme playing an important role in body metabolism. Supplements of vitamin B3 are also known to reduce levels of bad cholesterol and increase good cholesterol in the blood.

Pantothenic Acid is widely used for its effective use to treat acne. It is also used to relieve pain caused by rheumatoid arthritis and to relieve morning stiffness. Deficiency of Pantothenic acid is rare but can cause nausea, fatigue, headache and skin abnormalities. It plays a key role in the metabolism of carbohydrates and fats to release energy. It is also vital in antibody formation which helps in building immune system and preventing infections.

Selenium is a trace mineral that plays an important role in several metabolic pathways such as glutathione-peroxidise pathway. Selenium works with Vitamin E which gives its strong antioxidant effects and improves the immune system. It protects the body from prematurely aging. It also help prevent free radical damages that may cause heart diseases and cancer. It is essential in the proper function of the thyroid hormones, and promotes efficient metabolism. It is also beneficial in the reproductive health particularly of men because it facilitates in the sperm production, and prevents infertility. Selenium also helps reduce inflammation which is beneficial to those with rheumatism to reduce pain.

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 the second Vitamin that was discovered, after Vitamin B. It can be found in several forms, whereby the primary source is the natural retinol derived from animal food sources. Chemically related compounds are called retinoids and are used primarily in medicine and as dietary supplements beta-carotenes. While carotene forms stemming from dietary sources are not toxic, intake of synthetic and natural retinoid forms should be strictly limited. Vitamin A is found naturally in beef, pork, chicken, turkey and fish livers; in the sweet potato, carrot, broccoli leaf, butter, spinach, pumpkin, eggs, papaya, mango, peas, winter squash, apricot, cantaloupe melon and leafy vegetables. Vitamin A is necessary for normal reproductive capabilities, membranes, tissues, skin, eyes, normal tooth and bone development and much more.

Vitamin B12, 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 B6 is a water-soluble member of the vitamin B complex. It exists in thre forms and often occurs in nature as a mixture of these three forms. Vitamin B6 is involved in protein, fat, and sugar metabolism.

Vitamin C, also known as Ascorbic Acid, is water soluble vitamin. It is water soluble that leaves the body through urine. It plays an important role in the growth and repair of tissues in the body. It also important in the formation of collagen, a protein used by the body to make ligaments, blood vessel, scar tissue, and skin. It helps prevent osteoporosis and osteoarthritis. Vitamin C is an antioxidant that fights and prevents free radicals from damaging the cells that may result in premature aging, heart problems and cancer. Vitamin C also shortens the duration of colds and promotes quick recovery because it boosts the immune system. It also helps control blood pressure.

Vitamin D- The fast soluble vitamin D is perhaps the most underrated nutrient that is produced when sunlight touches the skin. But it is extremely vital for bone health, as without it the body cannot absorb the calcium that you may provide it in the form of supplements. With the advent of beauty products with high sun protection factor, this nutrient is becoming less available to our bodies. Even weaker sunscreens with just SPF-8 prevent the body considerably from producing vitamin D. Diseases such as arthritis, diabetes, certain cancers, multiple sclerosis, and even schizophrenia may stem from deficiency of this vitamin. You can provide vitamin D to your body through supplements and foods like mushrooms, tuna, eggs, dark green leafy vegetables, salmon, sardines, mackerel, fortified dairy products and cereals, yoghurt, and milk.

Vitamin E is the name for a group of tocopherols and tocotrienols that are soluble in fat and display antioxidant properties. The most important vitamin out of this group is alpha tocopherol, which professes the highest bioavailability, and therefore, was the most studied Vitamin E. Found in such foods as nuts, seeds, milk, wheat germ and most vegetable oils, this Vitamin is said to be perhaps the most important antioxidant in human nourishment, although this trait is not deemed the imperative reason why Vitamin E is required to be in every diet. Most clinical studies which were supposed to crown Vitamin E as the prevention from prostate cancer or cardiovascular wonder supplement have been either inconclusive or were discontinued due to poor results. Vitamin E deficiency results in neurological and neuromuscular problems, but also in failure to absorb fat.

Zinc is a metallic chemical element and an essential trace element, whereby only two to four grams of Zinc are found in the human body. There are several biological roles that Zinc plays in humans, including the metabolism of RNA and DNA, gene expression and the regulation of apoptosis. It is deemed vital for proper brain activity and essential in the learning process. It is also critical for the central nervous system, but is also found in muscle, bones, liver, kidneys, eyes and most prominently in the prostate. It is supplied to the body by the ingestion of red meats, particularly beef and lamb, but can also be found in seeds, including sesame and mustard, wheat, beans, whole grains, sunflower seeds and nuts, including almonds.
