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 dont 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 youre likely to have low levels of vitamin A.
