What is vitamin A and what does it do?

Vitamin A is not just one specific compound but is the name given to a group of unsaturated organic compounds that include: retinol, retinal, retinoic acid and some provitamin carotenoids. A provitamin a is simply a compound that the body can turn into a usable form of vitamin A. Beta-carotene is the most commonly know provitamin a. Carotenoids are organic pigments that are produced by plants and algae. Beta-carotene is the reason why carrots and apricots have an orange/yellow color. Beta-carotene is also found in leafy vegetables such as spinach and kale but the orange/yellow color is overpowered by chlorophyll.

Vitamin A and Vision

Vitamin A is crucial for vision. It is used to make another compound known as rhodopsin which is then used to absorb light in the retinal receptors. You might have heard stories or people say that if you eat carrots you can see better in the dark. Well, one of the symptoms of vitamin A deficiency is poor vision in low light or darkness. A vitamin A deficiency is rare in developed countries, however, a vitamin A deficiency during infancy could cause blindness. In addition, age-related macular degeneration could be helped by consuming foods containing carotenoids with antioxidant functions, such as beta-carotene.

In addition to being critical for healthy vision vitamin A also supports cell growth and plays a role in maintaining your heart, lungs, and kidneys healthy.

How much should you consume?

It is sometimes difficult to calculate exact vitamin A amounts. The reason for this is as I stated before, the term vitamin A is often used to refer to a group of compounds. Some compounds are more biologically available than others. This simply means that for some compounds the body can use them instantly and with others, there needs to be another event before they can be used. Beta-carotene falls into this latter category, it must be converted by the body into a usable form.

The following has been taken from the National Institute of Health‘s Fact sheet about vitamin A:

“Because the body converts all dietary sources of vitamin A into retinol, 1 μg of physiologically available retinol is equivalent to the following amounts from dietary sources: 1 μg of retinol, 12 μg of beta-carotene, and 24 μg of alpha-carotene or beta-cryptoxanthin. From dietary supplements, the body converts 2 μg of beta-carotene to 1 μg of retinol.”

The recommended dietary allowances are:

  • Men over 18 – 900μg
  • Women over 18 – 700μg

These figures are for 1 μg of retinol. This means that if the majority of your vitamin A comes in the form of beta-carotene (which the body converts at a ratio of 12 μg to 1 μg of retinol) the RDA is actually 10,800 μg for men and 8,400μg for women.

As a quick guide, most animal and dairy products primarily contain preformed vitamin A. In contrast vegetables (all of the ingredients shown above) primarily contain provitamin-A.
