Importance Of Vitamins

Vitamins Functions And Sources:

As micro nutrients, vitamins are required in small quantities. Generally your body cannot manufacture or synthesize vitamins from scratch. So you need to get them from the food you eat or from supplement pills. Though, vitamins can be synthesized by some bacteria, yeast, mould, algae and some plant species. Some vitamins like vitamin B5 have been found to be synthesized by bacteria in the human large intestines. However it is not clear if the vitamins are available for absorption and use by the body.

Vitamins are required by the body for a variety of biological processes. These include growth e.g Vitamin B6; mental alertness e.g Choline, Niacin; resistance to infection e.g. Vitamin C and Vitamin E. They also

These are water soluble and fat soluble vitamins.

i) Water soluble vitamins include : Vitamin C also called citric acid, Vitamin B1 (thiamine), Vitamin B2 (Riboflavin), Vitamin B3 (niacin), Vitamin B5 (pantothenic acid), Vitamin B9 (folic acid), Vitamin B6 (pyridoxine), Vitamin B12 (cobalamin), Cholin, Biotin.

Water soluble vitamins are not stored in the body in any appreciable amounts. The surplus is washed out mainly through urine. They requires consistent replenishing using the diet we consume. This makes them safe because they do not collect in the body toxic levels, making large doses of vitamin supplementary safe. But caution should still be practiced because mega doses have side effects and even can be fatal.

For example, there is a low risk of vitamin toxicity from nicotinic acid with mega doses. Nicotinic acid a derivative of vitamin niacin, one may experience flushing, itching, nausea and vomiting, liver cell damage. So supplement with daily value doses. Do not use megadoses unless under ongoing expert

Being fat soluble these vitamins are stored in the fat in our bodies. They can easily accumulate to toxic levels so if you choose to supplement be cautious.

Vitamin Deficiency:

The lack of these food factors i.e vitamins results to deficiency diseases. Vitamin defiency diseases are a manifestation of malfunctioning bio-chemical processes due to lack of the vital vitamins. Since the same vitamin may be used in a number of processes, deficiency in some vitamins can be quite serious and even fatal. For example over two hundred enzymes require the niacin vitamin coenzyme. So a lack of niacin makes this two hundred enzymes malfunction.

Vitamin deficiencies have been associated with long term latent deficiency diseases. These diseases occur after a long time of deficiency of some nutritional factors like vitamins. Long term latent deficiency diseases can be as severe as cancer, diabetes and heart disease. In our society today, these diseases are becoming the highest health concern.

The situation is grave because they are not only preventable but also cheaply preventable. A proper nutrition is all it takes to get all required nutrients including sufficient quantities of vitamins. General health benefits of vitamins include protection from a variety of diseases and
