Iron is one of the most commonly available chemical elements which are used in the form of metal. When in the presence of oxygen and moisture, iron gets oxidized very easily. Therefore it is never available on the surface of earth. Iron is a metal whose properties can be changed by mixing it with the various other metals. Humans need iron as a daily dietary substance. There are a number of supplements available in market which provides the daily required dose of iron. But the best way to consume iron is by eating the food that is rich in iron. Fish, poultry, beans, lentils, leafy vegetables are some of food items that are a good source of iron. Although, research shows that it is easier to digest the iron found in meat and meat products than the vegetables.

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.

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 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.
