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 is being considered a mineral with immense medical advantages, copper has been used as a supplement in its gluconate form. Copper is one of the most important constituents of the blood and prevents poly – unsaturated fatty acids from turning rancid. Copper also increases the health of the cell membranes and is actively involved in the formation of hemoglobin. Copper Gluconate is instrumental in treating conditions such as irregular beating of the heart, hypoglycemia, osteoporosis, osteoarthritis, and in lowering the cholesterol levels of the body. Copper Gluconate is known to have side effects and is toxic if taken excessively. In the case of women who are expecting or mothers who are nursing, it is advisable to consult with your docter before taking any Copper based supplements.

Folic Acid is really a family of several complex chemicals, but is generally referred to as one substance. It is present in all green leaved vegetables.

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 a necessary mineral for humans, needed for example to help form red blood cells which transport oxygen around the body. Fortunately there are plenty of good sources available for both the omnivore and the vegetarian or vegan These include liver, meat, beans, nuts, dried fruit , also whole grains and many of dark green leafy vegetables, although some such as spinach also contain substances that prevent the absorption of iron as do caffeine based drinks such as tea and coffee. On the other hand the drinking of fluids containing vitamin C aids the body in its necessary task of absorbing iron.

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 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, commonly called vitamin B5, is water soluble and is needed by every cell in the body to maintain good health. It helps in breaking down carbohydrates, fats and proteins to provide the body with energy. It assists in the production of red blood cells and hormones and ensures a healthy pregnancy. It is also known to lower triglyceride and cholesterol levels in the body. It helps in reducing stress and treating people with rheumatoid arthritis. Pantothenic acid is found in small quantities in almost all foods but abundantly in meats, fish, poultry, avocados, peas, broccoli and whole grains. A deficiency which is rare, leads to leg cramps, gastrointestinal problems, anemia, insomnia, depression, a burning sensation in the limbs and a weakened immune system.

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 a chemical element and a trace mineral deemed essential to human nutrition. It is found in many food sources, like beef liver, turkey, chicken breast, roast beef, white bread, whole eggs, rice, oatmeal, pasta, Brazil nuts, tuna and many others. Just recently a correlation between selenium, Vitamin E and cancer prevention has been scientifically proven. This essential trace element nutrient is nevertheless toxic in excessive doses, but is vital as a cofactor where antioxidant enzyme glutathione peroxidase is required. Besides the belief that selenium may have a role in prevention from cancer, it has been observed that population in HIV and AIDS stricken countries where the soil is deficient in selenium have larger outbreaks than areas where selenium is sufficiently present. Other uses, such as in prevention from recurrence of tuberculosis, have been recommended by researchers.

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 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, also known as cobalamin, which is naturally found in foods such as fish, milk and milk products, eggs, meat and poultry. Vitamin B12 is important for good health, necessary for the proper digestion and absorption of foods and for normal metabolism of carbohydrates, and fat. It helps maintain healthy nerve cells and red blood cells and is needed to make DNA. Vitamin B12 is bound to the protein in food. Hydrochloric acid in the stomach releases B12 from protein during digestion. Unlike other water-soluble nutrients, vitamin B12 is stored in the liver, kidney, and other body tissues. It can take several years before signs of the deficiency appear due to poor dietary intake. Vitamin B12 functions as a "methyl donor." A methyl donor is a compound that carries and donates methyl groups to other molecules, including cell membrane components and neurotransmitters. As a methyl donor vitamin B12 is involved in homocysteine metabolism and plays a critical role in proper energy metabolism, immune function, and nerve function. Therefore, vitamin B12 is clearly an added benefit for anyone wanting to lose weight, as without it, metabolism is not at its peak potential.

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 acknowledged as essential to the human organism. It is a trace element found in over a hundred and up to three hundred enzymes. It is the second most important mineral in the body, after iron. Zinc is also defined as an important catalytic agent, which is active in enzymatic reactions such as hydroxilation, which is essential for the protein forming amino acid proline, but also for hypoxia response. Zinc is naturally found in red meat, milk, spinach, nuts, oysters, beans and oats. Low zinc counts can attribute to a weakened immune system, interfere with muscle building, cause diarrhea and all kind of other deficiencies. In body building circles, Zinc is an important supplement, valued for the indirect increment of testosterone and the muscle building role.
