Carotenes absorption and metabolism

Carotenoids need bile acids for absorption and unless they are converted to vitamin A in the wall of the small intestine, they are absorbed unchanged. Conversion appears to depend on several factors including protein, thyroid hormone action, zinc and vitamin C.
Around 40 to 60 per cent of dietary beta carotene is absorbed, although this appears to be reduced in the presence of low stomach acid. Beta carotene can be stored in the lung, liver, kidneys, skin and fat.
