Biotin, also known as vitamin H, but is more commonly called Biotin. It is a vitamin which is B-complex in nature and is water soluble. Biotin helps in transferring carbon dioxide along with helping in various metabolic reactions. A steady blood sugar level can also be maintained by the help of biotin. Hair and nails are strengthened by the consumption of biotin. Therefore, a lot of hair and cosmetic products use biotin as one of its ingredients. The body’s daily requirement of vitamin B7 is produced by the intestinal bacteria. This therefore reduces the chances of vitamin B7 deficiency. There a large number of foods that contain biotin in large quantities. Swiss chard, tomatoes, liver,eggs, almonds, cumcuber, cauliflower, legume, soybeans, raspberries, carrots are some of those foods.

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 an essential mineral that plays an important role with how the body uses glucose. Chromium may be found in brewer’s yeast, grains, cereal and in some beers. It aids in maintaining the ideal blood sugar level which helps diabetic patients. It also helps in the metabolism and storage of fats, proteins and carbohydrates in the body that may help reduce fats. It helps improve muscle tone by burning the fats. It reduces hunger pangs, suppress cravings and appetite. It is help control the blood cholesterol level. It lowers the risks of cardiovascular problems. It also alleviates depression by stimulating the fatty acid and cholesterol synthesis that is important for brain function.

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.

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, also called vitamin B5, which is a water-soluble vitamin required by the human body. Pantothenic acid is needed to form coenzyme-A (CoA), and is vital in the metabolism and synthesis of carbohydrates, proteins, and fats.

Phosphate (Phosphorus) is a chemical element that is found in the periodic table with the atomic number fifteen. As a high reactive element, it is not found in clean form as a free element in nature. It is one of the most important and essential elements in the human body, being found in phospholipids that form all the membranes of cells, the DNA, the RNA and also the ATP. Cellular energy is being transported by phosphate in form of adenosine triphosphate, calcium phosphate, which are salts, are responsible for the stiffness of bones. In the average human, the amount of phosphorus in weight would be about one kilogram, whereby most of it is in form of apatite and found in teeth and bones. The daily consumption of phosphorus through dietary means is estimated at about one to three grams.

Potassium, a mineral that is quite common in our food. Potassium is needed for proper muscle growth, nervous system and brain function and to help balance the PH of our bodies.

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 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.

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 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.

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, 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.
