How Important are Vitamins!!

Normally, hypervitaminosis of water soluble vitamins does not occur as they are not stored in great quantities in the body. Therefore, they are required daily through diet.

Now the question arises that, it is safe/ beneficial to take vitamin supplements instead of natural vitamin? Research has proven that vitamin pills are a waste of money, usually offer no health benefits and could even be harmful. Evidence from a study even suggested that “supplementing the diet of well-nourished adults…has no clear benefit and might even be harmful”.Recent studies have shown that too much beta carotene and vitamin E can cause cancer, and it’s long been known that excess vitamin A can cause liver damage, coma and death.

Despite being labelled ‘natural’, over 90 per cent of vitamin supplements on sale are synthetic.

New evidence is emerging that these unnatural forms of vitamin could do more harm than good. Also they are much more useful to the body in their natural forms.

Vitamins and Minerals are required in very small quantities as compared to carbohydrates, proteins and fats, but these are essential for the metabolism of these macro- nutrients. Vitamins have every important biochemical functions. Some of them have hormone like functions as regulators of mineral metabolism or regulators of cell and tissue growth and differentiation. Vitamins like Vitamin A, C and E act as antioxidants. B complex Vitamins function as precursors of enzyme cofactors, without which the enzymes cannot function as catalysts in metabolism. Vitamins are tightly bound to enzymes as part of prosthetic groups. Although these roles in assisting enzyme-substrate reactions are vitamins’ best-known function, the other vitamin functions are equally important.
