Beta Carotene Description

Description:

The precursor form of vitamin A which means that beta-carotene is converted to vitamin A in the body on an ‘as-required’ basis. This makes it safe during pregnancy when high levels of vitamin A itself (retinol) should be avoided. Beta-carotene acts as an antioxidant in the body, neutralising potentially damaging free radicals.

Food Source:

Fruit and vegetables such as carrots, red pepper, spinach (and other dark green leafy vegetables), mango, peaches and apricots (60 per cent of the average UK intake comes from carrots). Levels are stable during cooking, but losses occur due to exposure to light and air.

Intake:

EU labelling RDA: Not established. There is insufficient evidence to make any specific recommendations about consumption. Five portions of fruit and vegetables per day will usually provide about 6mg of beta-carotene. However, apples, bananas and onions provide almost no beta-carotene.

Deficiency Symptoms:

None known.

Who might Benefit from supplements:

Skin conditions sensitive to sun.

Side Effects/Precautions:

High intakes are not recommended for smokers as two separate studies show that taking synthetic beta-carotene may increase the risk of lung cancer/death in smokers. Unlike vitamin A, beta-carotene is safe before and during pregnancy.
