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.

Folate is a water-soluble B vitamin that occurs naturally in food and helps produce and maintain new cells.

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 trace mineral that has long been associated with musculoskeletal health. It activates enzymes in the body that is necessary for the production of collagen and proteoglycan, components of connective tissue. It also aids in the absorption of calcium in the body. It helps prevent the development of osteoporosis and osteoarthritis. Manganese helps in the digestion and utilization of vitamin E in the body that makes it a potent antioxidant. It fights free radicals from damaging the cells that may lead to premature aging, heart problems and cancer. It alleviates premenstrual syndrome (PMS) such as mood swings and nausea.

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, 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.

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.

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- Otherwise known as retinol is the vitamin which helps the eyes to adjust to changes in light levels as well as keeping the eyes, skin and mucous membranes moist. Vitamin A enters the human diet mostly from animal foods, but as well as this some plant foods contain beta-carotene, which the body is then able to convert into Vitamin A. Retinol has antioxidant properties that help the body to repair tissue and cellular damage by neutralizing free radicals. Although there seems to be some evidence that retinol may help in cases of established artery disease the American Heart Association does not recommend it as a necessary supplement until there is more evidence.

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 is L-ascorbic acid, or the active component of Vitamin C. Ascorbate, which is an ion of the ascorbic acid, is required for many metabolic reactions and is manufactured internally by most organisms, except humans. It is an essential nutrient and needs to be provided through nutrition. While oranges were traditionally deemed a good source of Vitamin C, the amount provided by an orange is dwarfed by the amount provided by the kakadu plum the richest Vitamin C plant resource of the world. Other notable sources are red peppers, parsley, Kiwifruit, Guava, Broccoli, Camu Camu, rose hip, Jujube, papaya, strawberries, lemon, melon and similar. Vitamin C is essential for tyrosine, carnitine and collagen synthesis, is the most widely available antioxidant and furthermore is vital for blood vessels, cartilage and scar tissue.

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.

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 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.
