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.

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.

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 is the chemical element found in the periodic table with the atomic number 12. This alkaline earth metal is one of ten most common elements in the known universe and also very prominently present in the human body. It manipulates polyphosphate compounds, most prominently the DNA, RNA and the ATP. Numerous enzymes rely on magnesium ions to function properly. Most common application of magnesium in medicine may be the addition to antacids and laxatives. This metal is not found as a free element naturally on Earth, generally the metal is obtained through electrolysis of magnesium salts. The most common deficiency in the United States with staggering two thirds of the population is the magnesium deficiency. Magnesium can be obtained through vegetables, tea, cocoa, cereals, coffee, nuts and spices.

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 is also known as Vitamin B3 or nicotinic acid. It helps in the conversion of carbohydrates into glucose that serves as fuel for energy. It also helps the body in metabolizing fats and proteins. Niacin also helps in the production of hormones necessary for the body to function properly. It is also effective in improving the circulation in the body. It lowers cholesterol, triglycerides and blood sugar level. It also helps in the treatment of coronary artery disease. It also helps in regulating the blood sugar level. Niacin also helps prevent the Pellagra disease, which causes digestive problems, diarrhea, dermatitis, hyper-pigmentation, amnesia, dementia, delirium, and even death. Niacin also helps prevent Alzheimer’s disease, diabetes, and is also effective in treating acne.

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.

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.

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.

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 a vitamin is needed by the retina of our 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 mainating body health, such as skin health, bone metabolism and immune function. Vitamin A is also commercially produced and administered as esters such as retinyl acetate commonly called Vitamin A acetate. Its defeciency can cause blindness. Some other problems include impaired immunity, keratosis pilaris and squamous metaplasia of the epithelium lining the upper respiratory passages and urinary bladder to a keratinized epithelium.

Vitamin B12- Also called Riboflavin, B2 is a water absorbed vitamin of which the body must replenish its supplies each day as it cannot be stored. It is necessary for the production of red blood cells and, like the other B vitamins, it works at supporting it supports energy production by helping in the metabolism of various foods.B2 is required for healthy skin as well as hair growth, the nails and has a role in regulating the activity of the thyroid gland. It is also necessary in order that the body can process amino acids found in proteins and fats and to activate vitamin B6 and folic acid.

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.

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 consists of eight related vitamins that are all fat soluble and have antioxidant properties. The alpha-, beta-, gamma- and delta-tocopherols with the corresponding tocotrienols all belong to the Vitamin E group, whereby the alpha-tocopherol has been found to be the most bioavailable form. Vitamin E is commonly found in food sources like eggs, milk, nuts, seeds, vegetable oil like olive oil, wholegrain foods, wheat germ, red palm oil, but also in asparagus and avocado fruits. While Vitamin E is a powerful antioxidant, several other properties have been noted as well, such as prevention of damage to neurons, cholesterol reduction and cancer prevention. Vitamin E has been also identified as a vital signaling molecule, whereby the primary necessity of Vitamin E to human survival is still not clear.

Zinc, a mineral needed for cell division and repair as well as proper functioning of the immune system. Zinc is also an important antioxidant that neutralizes free radicals in the body.
