Facts About Vitamins - Vitamin a (retinol)

Vital Vitamins - Vitamin A (Retinol)

Vitamin A - also called Retinol - is an important dietary supplement. It aids eyesight

and bone formation, is essential to maintain the lining of the digestive tract and also helps in

keeping the eyes, skin and mucous membranes moist. Vitamin A is found in certain foods but

also can be derived in the body from what are known as carotenes. Vitamin A is a fat soluble

vitamin.

How much do we need? The current UK RNI (reference nutrient intake) for vitamin A for an

adult woman is 600 - 700 micrograms (mcgs), this rises for women who are pregnant

or breastfeeding. For an adult male 700mcgs is recommended. In the US the RDA

(recommended dietary allowance) for women is 800mcgs and 1000mcgs for men

And if we don't get enough? Whilst a deficiency of vitamin A is rare it can lead to symptoms

which may include; eye problems, weight loss, poor skin condition, vulnerability to coughs

colds, diarrhoea and impaired growth.

And too much? Symptoms of too much may include dizziness, nausea, impaired growth and

hair loss.

Who needs extra? People who are on a low fat diet may need supplementation, if your diet is

low in fresh fruit and veg and high in processed refined food you're likely to have low levels of

vitamin A. The same goes for people who consume more than modest amounts of alcohol or

live or work in a polluted area.

Sources of vitamin A include:



  • margarine


  • butter


  • cheddar cheese


  • liver


  • boiled eggs


  • full fat milk


  • smoked mackerel




Foods that contain carotenes include:



  • sweet potato


  • carrots


  • spinach


  • red pepper


  • broccoli
