Functions of Vitamins
Vitamins are essential for the normal functioning of our bodies. It empowers the body to process other nutrients successfully. Although vitamins by themselves do not give the body energy without vitamins most other nutrients can not be processed successfully. Vitamins help regulate metabolism, help convert fat and carbohydrates into energy, assist in forming bone and tissue for growth, body maintenance, vitality and general wellbeing.
Sources of Vitamins
All natural vitamins are organic food substances found in living things like plants and animals. With a few exceptions (like vitamin D, which can be made within the skin) the body cannot manufacture or synthesize vitamins it must be supplied in our diet or in dietary supplements.
Required doses of vitamins
Although vitamins are essential for life, we do not need a lot of them. In states of good health and a well-balanced diet, we can get the vitamins we need from the food we eat. In states of altered metabolism (including mental and physical stresses, and during or following an illness) and when the pace of modern-day living prevent us from following a well balanced diet, though, we may need greater amounts or supplementation of vitamins.
Classification of vitamins
13 different vitamins are divided into two types, water soluble and fat-soluble.
Water-soluble vitamins include the vitamin B group, vitamin C and H (Biotin). The body does not store these vitamins for long periods of time. Deficiencies of these vitamins are very likely to occur if proper dietary care is not taken. Good quantities should be eaten every day.
Fat-soluble vitamins include vitamins A, D, E, and K. The body follows the same paths to absorb fat-soluble vitamins as it does to absorb other fats. Any condition interfering with the absorption of fat would also result in poor absorption of these vitamins. These kinds of vitamins however are stored better (for longer periods of time) by the body.
The recommended dietary allowance (RDA)
RDA is the recommended minimum amount of a nutrient to be consumed daily. It indicates the minimum of the nutrient to maintain normal nutritional status in healthy people and not the recommended ideal amount for a specific individual. For example, the RDA for vitamin C is 60 milligrams a day – just enough to prevent scurvy in a healthy sailor!
The body also store some nutrients better / longer than others which highlight the importance of regular balanced intake of most nutrients. A therapeutic dose of a nutrient is usually increased considerably, but the toxicity level must always be kept in mind.
