Getting To Know All The Vitamins

We list all vitamins that are found in human, animal as well as plants that help in maintaining good health. Peruse the list below and see what individual vitamins does! And more..






Because the body cannot synthesize or make vitamins by itself, it is very important we get the right type and amount of vitamins from our meals.

Getting to know the list of all vitamins, what they do, how much of each is needed daily by our body, and where to get them from, is vital if we must know and master how to employ these "vital amines" for optimal benefit.

There are thirteen (13) different vitamins known to man. They are generally classified into two groups: fat soluble and water soluble vitamins. This classification is only done to reflect the medium in which the vitamins are dissolved and easily found. We need both types or classes of vitamins for maintaining good health and conquering diseases.

We list all vitamins in both groups together as well as provide a brief summary of what they do and where they can be found. They are:

Vitamin A

Vitamin A is also called Retinol.

It is a fat soluble vitamin. This compound in it's original form can only be found in food of animal origin. It's preformed analogue is found in fruits and vegetables as carotene. Carotene is split by the enzymes of the intestines to form vitamin A (that is why carotene is often referred to as Pro-Vitamin A).

Vitamin A is essential for good vision. It is also important for proper growth and development of the unborn child. Vitamin A helps in maintaining the structure and integrity of cells that line must surfaces and cavities in our body...cells called epithelial cells. It also helps in enhancing fertility, good sperm motility, and protection against infections.

The Recommended daily allowance (RDA) of vitamin A is any thing from 500 to a maximum of 6000 IU (international unit) of this vitamin. Taking too much vitamin can cause very serious side effects.

Vitamin A can be obtained from:

  • Liver
  • milk
  • Cheese and butter
  • Carrots

A lack of vitamin A leads to problems like "night blindness", which is an inability or decrease ability to see in dim light. A deficiency of this vitamin can also lead to inflamed and sore eyes, dry and rough skin, poor sperm motility an problems with fertility, as well as increased susceptibility to infections.

Taking too much vitamin can lead to vitamin A toxicity. The symptoms and signs of vitamin A toxicity include:

  • Rough skin
  • Dry fluffy hair
  • Enlarged liver and abdominal pain
  • Severe headaches
  • Malformed babies if taken injudiciously in pregnancy
  • Blood disorders like raised erythrocyte sedimentation rate.
Over dose of vitamin A does not occur from the consumption of carrots or fruits an vegetables. This is because, for carotene to be converted to Vitamin A, there must be a deficit in the body.More on Vitamin A here
