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 mineral that plays an important role in the development of the human body. It is common knowledge that calcium is important in preventing osteoporosis. However, calcium also provides structural support in the development of muscles. Deficiency in calcium could cause obesity because it triggers the release of parathyroid hormone that stimulates the production of fats in the body and inhibits its breakdown. It also reduces the blood pressure. Calcium also has the ability to fight colon cancer by binding itself with cancer cells to inhibit its growth and progression. It is also beneficial to women suffering from PMS or premenstrual syndrome such as depression, mood swings, anxiety, water retention, breast tenderness, and headaches.

Chloride is an electrolyte that works with potassium and sodium. Electrolyte dissolves in water and carries an electrical charge, and because human body is made up of water, the Chloride can easily move around the cells of the body. Chloride helps in carrying the nutrients in the body, ridding the body of excess water and regulating the acidity in the body. Chloride also plays an important part in process of metabolism and digestion. Chloride is an essential element that makes up Hydrochloric acid in the stomach that used for digestion. Chloride helps in losing weight safely because it promotes better metabolism and better digestion while ensuring the proper nutrients are distributed in the body.

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 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 is an important trace element that plays an important role in the normal growth and development. It essential in maintaining a healthy thyroid gland which, kills harmful germs, makes up its own hormone thyroxin, and gives energy. It assists in maintaining a proper metabolic rate which can influence the blood pressure, heart rate, temperature, and body weight. It is also important in the utilization of calories for energy. It plays an important role in hair, nails and teeth growth. Iodine also aids in the normal growth and maturity of reproductive organs. It also helps prevent still birth or neurocognitive conditions in babies.

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 a micromineral needed by the body for the metabolism of purines, a protein component of the DNA. Microminerals are minerals required by the human body in minute amounts (<0.005% of body weight) for enzymatic reactions. These are also known as trace elements. Molybdenum, although needed and present in the body in small amounts, it is as significant as the B-complex vitamins and Magnesium. Found abundantly in the liver, kidneys, adrenal glands and blood cells, it exists in bound form as a central part of various enzyme molecules. Some of these enzymes are: xanthine oxidase for the oxidation of xanthine to uric acid; liver aldehyde oxidase, a flavoprotein, for catalyzing the oxidation of aldehydes to corresponding carboxylic acid; and, sulfite oxidase which affects degradation of amino acid-derived sulfur. It is excreted in the urine. Molybdenum toxicity has not been observed in humans but high intakes of molybdenum can alter the activity of alkaline phosphatase and produce bone abnormalities. Doses above 10-15 mg each day causes gout-like symptoms.

Niacin, also called Vitamin B3, is a water-soluble vitamin needed for the conversion of food into energy so that it may be used by the body. Niacin also helps metabolize protein, sugar and fat.

Pantothenic Acid is also called vitamin B5 (a B vitamin). Its chemical formula is C9H17NO5 and Mol. Mass is 219.23 g mol-1 . It is a water soluble type of Vitamin B and an essential nutrient for life. Pantothenic acid is critical in the metabolism and synthesis of carbohydrates, proteins, and fats. It is used in some hair and skin care products .Pantothenic acid supplements are used to fulfill vitamin deficiency. Research also shows that these supplements reduce the duration of morning stiffness, degree of disability, and pain severity in rheumatoid arthritis patients.

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, 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 trace mineral that plays an important role in several metabolic pathways such as glutathione-peroxidise pathway. Selenium works with Vitamin E which gives its strong antioxidant effects and improves the immune system. It protects the body from prematurely aging. It also help prevent free radical damages that may cause heart diseases and cancer. It is essential in the proper function of the thyroid hormones, and promotes efficient metabolism. It is also beneficial in the reproductive health particularly of men because it facilitates in the sperm production, and prevents infertility. Selenium also helps reduce inflammation which is beneficial to those with rheumatism to reduce pain.

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 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, also known as Pyridoxine, Vitamin B6 is an essential vitamin to aid in the formation of healthy red blood cells and supports more vital bodily functions than any other vitamin. A water-soluble vitamin, Vitamin B6 is needed to release energy from the food we eat. Vitamin B6 cannot be stored in the body, so it must be obtained daily from either food or supplements. Vitamin B6’s role as a coenzyme involved in the metabolism of carbohydrates, fats, and proteins is what makes it important for dieters. Vitamin B6 is also responsible for the manufacture of hormones, red blood cells, neurotransmitters, enzymes, and prostaglandins. Vitamin B6 is required for the production of seratonin, a brain neurotransmitter that controls mood, appetite, sleep patterns, and sensitivity to pain. For weight loss, dieters should include vitamin B6 to increase their metabolism while rounding out a healthy diet.

Vitamin C or ascorbic acid, is also known as the antiscorbitic vitamin because it prevents the nutritional disease Scurvy. Its most active form is L-ascorbic acid and L-dehydroascorbic acid. Vitamin C is known for building up the body’s defenses against infection. However, there is more to this vitamin than just being an immunity-builder. It is essential to normal functioning of all cellular units including ribosomes and mitochondria. This is because it is a primary requirement in the formation and maintenance of the “binder” that holds cells as well as the cellular fluid inside. Furthermore, this water-soluble vitamin is necessary in the conversion of folic acid into its active form, folinic acid, necessary for the formation of red blood cells. It also speeds up wound and fracture healing, is involved in metabolism of some essential amino acids, plays a role in the production of steroid hormones for stress response and promotes the absorption of iron for the body to use. It is also an antioxidant vitamin that protects normal cells from the damage of oxidative free radicals.

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.

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.
