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.

Choline- Grouped with the Vitamin B complex, choline is deemed an essential nutrient. It is a natural amine and an organic compound, which serves several physiological purposes. Choline improves the structural integrity of cell membranes and provides signaling roles, assisting with the system of communication, which controls basic cellular activities and manages cell actions. Deemed a nootropic drug, choline as a dietary supplement is supposed to increase the cognitive behaviour and alertness. As a building block of the neurotransmitter acetylcholine, choline certainly seems to be nootropic, but recently the application of choline as a nutritional supplement helping to reduce body fat because of the activity in the lipid metabolism was observed. Infant formulas that are not derived from cow’s milk are ordered by the FDA to supplement choline.

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.

Damiana is a shrub belonging to the family of Turneraceae. Even though it is a small shrub, it produces aromatic, small flowers. It is generally found in the regions of South America, Caribbean, Mexico and Central America. It is also a fruit bearing shrub. The flowers generally blossom in late summer on the damiana shrub. Then the fruits follow. The fruit it bears is quite similar in taste to figs. It emits a smell which is quite similar to the odor of chamomile.

Inositol is a carbocyclic polyol found in fiber rich food items such as bran, wheat or legume. Even though it is a form of sugar, it works differently from glucose. With the help of several nutrients and vitamins like B6 and B12, inositol controls fat accumulation in the liver. It is also effective in the treatment of diabetes, low blood cholesterol levels and liver problems. This essential component helps in the formation of cell membrane that allows passage of molecules in and out of the cells. It also affects the signaling molecules of the body and is important for pleasure (serotonin) activity of the brain. Some of the good sources of inositol are kidney beans, cereals with bran content and fruits like oranges and cantaloupes.

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.

Lutein is concentrated in retinas of eyes and is vital for good vision. It has many positive benefits for the eyes, particularly when compounds lutein and xeaxanthin are mixed. Xeaxanthin helps increase the affect. A diet that is rich in lutein can lower the risk of developing cataracts and macular degeneration. It may also prevent or decelerate atherosclerosis, thickening of arteries, which is one of the major risks for cardiovascular disease. Since it is an antioxidant, lutein removes free radicals from the body. Lutein intake also benefits the cardiovascular system. It also has benefits for skin and keeps it healthy. Lutein can also reduce growth of colon cancer.

Lycopene is a phytochemical which belongs to a class of substances called carotenoids. From the point of view of structure, it is a tetraprene, and because it contains only carbon and hydrogen it is also classed as a carotene. It is bright red in color and is found naturally in red fruits and vegetables, such as tomatoes, watermelons and red carrots. Lycopene is water insoluble and is transported in the body bound to lipoproteins. Preliminary research has indicated its efficacy against certain cancers. It is a strong antioxidant and acts as a singlet oxygen quencher. Singlet oxygen forms in the body due to ultraviolet light exposure and is involved in aging and cardiovascular disease. Other proposed benefits could be in conditions, such as diabetes, osteoporosis and male infertility.

Magnesium is a mineral that may be found inside most of the cells in the body tissues and organs. It is important in the absorption of calcium and aids in the formation and development of bones and teeth. Magnesium deficient individuals have an increased risk of acquiring osteoporosis; they also have problematic menstrual cycle such as premenstrual syndrome, irregular cycle and dysmenorrhoea. Magnesium helps in maintaining the cardiovascular health and decreases the risk of heart problems. It also prevents gallstones from forming. Magnesium is useful in the treatment of high blood pressure. It is also helpful in treating erectile dysfunction and prostate problems.

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.

Pantothenic Acid, commonly called Vitamin B5, it is a water-soluble member of the vitamin B complex. Pantothenic acid is involved in adrenal gland function and is required to fight stress.

Para-Aminobenzoic Acid is best known as an effective sunscreen as it blocks the ultraviolet rays from the sun. However it is also used to improve the protein used in the body and plays a role in red blood cell formation as well the manufacture of folic acids in the intestines. Some people have reported the reversal of gray hair and improvement of "age spots".

Saw Palmetto , also known as Serenoa repens, which is the only species from the genus Serenoa in the Arecaceae family. Arecaceae are actually all palm trees and Saw Palmetto is no exception. It is a smaller version of a palm tree with heights that do not surpass four meters. It is believed to be native to southeast of the United States, the oldest plants found in Florida with almost 700 years of age. The berry-like fruits are rich in fatty acids and plant sterols and Saw Palmetto extract has been often used for treatment of urinary tract problems, mainly infections. Some other applications related to cholesterol have been evaluated, but no indications were proven. Treatment against benign prostatic hyperplasia is currently under evaluation, whereby initial data was encouraging, but methodological research data contradictory.

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.

Vitamin A is a fat-soluble vitamin with known toxicity. Although its toxicity has been exaggerated, it is a factor worth keeping in mind. Carotine is converted in the human body to Vitamin A, it comes from vegetable sources. Vitamin A is necessary for normal growth and for skeletal development.

Vitamin B1, also called Thiamin, is needed to help the body utilize energy from proteins, fats and carbohydrates. Vitamin B1 is commonly found in breads and cereals. Vitamin B1 is water-soluble and is concentrated in muscle tissue as it passes thru the body.

Vitamin B12 is required for the normal functioning and development of the nervous system, blood cells and brain. It’s a water soluble vitamin which is used to elevate mood, improve energy levels and concentration, to boost immune system and in sleeping disorders. Severe deficiency of Vitamin B12 can lead to pernicious anemia. It is also used for lowering high homocysteine levels which may contribute to heart disease, asthma, AIDS, to prevent cervical and other cancers, memory loss, osteoporosis, allergies and skin infections. It also helps to prevent atherosclerosis, multiple sclerosis, and kidney and gum disease. Vitamin B12 is added in almost all multi-vitamin B complex supplements. Deficiency of Vitamin B12 in infants can lead to megaloblastic anemia, delayed developments and movement disorders. Studies have proved that when used in combination with folic acid, it can prevent heart diseases.

Vitamin B2 , an easily absorbed micronutrient, is also known by the name of Riboflavin. 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.

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

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- The essential nutrient L-ascorbic acid, or rather Vitamin C, is necessary for a wide plethora of metabolic reactions in almost all living beings. In humans, Vitamin C is vital in the collagen synthesis. While most beings are able to make it internally, apes and humans cannot. Interestingly enough, while widely promoted as the best dietary source of Vitamin C, Oranges are dwarfed by the Kakadu plum, which has sixty times the amount. Prominent are rose hips, blackcurrant, red peppers, parsley, the kiwifruit, broccoli, redcurrant, several berries including strawberries and raspberries, as well as more exotic fruits and vegetables like Camu Camu, acerola, seabuckthorn, Indian gooseberry, jujube, guava and baobab. Tomatoes, while very popular Vitamin C source in the US, are very low on the Vitamin C scale.

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 a mineral found in most cells in the human body. It plays an important role in stimulating enzyme functions. It improves the immune system that protects against bacterial and viral infections. It also promotes healing of wound.
