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 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.

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- We know Folic acid by various names - Folate, Folacin, Pteroylglutamic acid, or just Vitamin B9. No matter what we call it, Folic acid is basically a B vitamin that helps the body to create healthy new cells. Folic acid is thus necessary for each one of us though pregnant women require it all the more. A woman who has a sufficient intake of folic acid both before and during pregnancy can protect the baby from major birth defects of the brain or spine. The best part about this vitamin is that it is readily available in fruits, dried beans, nuts, peas, cereals, grain products, and leafy green vegetables. It is however important to consume this vitamin regularly through proper diet. This is because folic acid being water soluble, it easily dissolves in water and the leftover vitamin is passed out through the urine.

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.

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 or vitamin B5 is a water soluble vitamin that may be found in various food sources such as fish, meat, broccoli, and egg yolk. It forms part of the coenzyme A (CoA) that is important in converting the food we ingest into energy. It stimulates the production and transportation of energy from fats. It also helps in maintaining a healthy digestive tract and prevents the liver from becoming fatty. Pantothenic acid is also known for preventing stress. It enhances the immune system and protects the body against various infections. Studies also showed that increases the level of zinc in the body that helps reduce acne and pimple breakouts.

Phosphate (Phosphorus) is the chemical element with the atomic number 15 in the periodic table. It is not found as a free element anywhere in the world. In biology and biochemistry it may be the most important element, being present in all living cells of living species. It is present in the DNA, in the RNA, in ATP, but is also found in cell membranes in form of phospholipids. It is also present in the bones, where it builds calcium phosphate salts, responsible for strong bones. Apatite is a collection of phosphate minerals which are generally found in bones and teeth; namely bromapatite, fluorapatite, chlorapatite and hydroxyapatite. Several phosphates are being added to body building supplements and powders, intended to aid in skeletal and cellular strength improvement.

Potassium- Potassium is one of the essential minerals required for proper physiological functioning of the body. It plays an important role in the regulation of heart muscles. It helps to convert glucose to glycogen. Glycogen is essential for muscle formation. Potassium also helps to propagate nerve impulses by exchanging ion within cells and also helps in muscle contractions. It helps in balancing blood pressure. It controls the proper functioning of kidney. An average adult needs 3-5 gm of potassium daily. Due to deficiency of potassium, body observes tiredness. Other deficiency symptoms are weakness of muscles, low blood pressure, vomiting, poor kidney functions and Heart arrhythmias. Severe potassium shortages quickly direct to electrolyte disproportion which involves malfunctioning of nerves, kidney and heart.

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 is considered good for health if taken in small amounts. It is a trace mineral which when incorporated into protein, makes selenoproteins that helps stop cellular damage due to free radicals. The major source of selenium is plant foods and its content in the food depends on the selenium content in the soil where it was grown. Also known as selenium acid, selenium sulfide and selenium yeast, this mineral is available in seafood and meat products. The main function of selenium is to work with vitamin E in order to maintain the elasticity and preservation of tissues. It not only helps in improving the supply of oxygen and blood to the muscles in the heart but also slows down the aging process by enhancing endurance.

Sodium is the element that has the atomic number 11 in the periodic table and is commonly known as the main component in the table salt, together with chloride. Interestingly enough, it is probably the one dietary component which does require limitation rather than supplementation, since that average daily nutritional requirement is around half a gram per day. This most popular food seasoning, salt, is providing the most common source of sodium and chloride in human diets, but is generally overused and may cause health problems, such as high blood pressure, if consumed overly generously. The suggested dose of table salt, or rather the upper limit portion, would be somewhat less than 6 gram per day, according to the Dietary Guidelines for Americans, referenced by FDA. In the UK this limit is set at four grams per day.

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-souble member of the vitamin B complex. Requirements are in the microgram range, which is lower than the milligram range of the other B vitamins. Vitamin B12 is involved in the production of red blood cells and is usually known as the anti-anemia vitamin.

Vitamin B6, also known as Pyridoxine, plays an important role in the breakdown of protein, fats and carbohydrates. It helps in the production of antibodies that keeps the immune system strong. It promotes red blood cell (RBC) production. It alleviates the symptoms of premenstrual syndrome or PMS such as headaches, bloating, depression, mood swings, and abdominal pains. Vitamin B6 also prevents the development of kidney stones. It also helps reduce the build-up of homocystein in the vessels that may cause hearth attack. Vitamin B6 is also beneficial in the overall nerve health. It also prevents or decreases the susceptibility to develop carpal tunnel syndrome.

Vitamin C is well known for its powerful ability to help boost the immune system as well as fight off damage causing free radicals. As an anti-oxidant, vitamin c binds with free radicals, preventing them from damaging cells. This damage can cause early aging and even has been linked to some cancers. By taking vitamin C supplements, you are helping prevent these free-radicals, as well as giving your immune system a boost as well. Vitamin C is integral to cellular metabolism as well and a lack of vitamin C can cause a myriad of issues, including scurvy.

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 is a fat-soluble vitamin and is an antioxidant. Vitamin E helps to gradually break down blood clots in the circulatory system and helps prevent more from forming. Involved in red blood cell formation.

Vitamin K- The lipophillic, hydrophobic vitamins needed for the posttranslational modification of certain proteins is denoted by the Vitamin K. It is required mostly for blood coagulation. K3, K4 and K5 are the three types of synthetic Vitamin K that are used in many areas. Pet food industry makes use of Vitamin K3 whereas Vitmanin K5 is used to inhibit fungal growth. The main sources of vitamin K are spinach, cauliflower, broccoli, cabbage and a few fruits like kiwifruit and avocado. Recent research shows that vitamin K helps in increasing bone mass. Research also shows that the consumption of vitamin K helps in promoting osteotrophic processes while at the same time slowing the osteoclastic processes. This process is done by achieving the calcium bonding in the bones.

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.
