Vitamin A (Retinol) Information - For Better Eyesight

Approximately 80% of vitamin A is absorbed in the human system. It is passed along with fat through the lymphatic system into the bloodstream. The absorption of vitamin A increases if it is taken with fats. Absorption is more rapid in men than in women. The absorption of this vitamin is poor in cases of diarrhoea, jaundice, and abdominal disorders. Vitamin A is stored in the liver. A healthy person can store about 97.2 mcg of vitamin A per g of liver. Thus an average liver weighing 1500 g can store 150,000 mcg of vitamin A.

Approxiately 20% of vitamin A which is not absorbed is excreted within one or two days into the faeces. Of the 80% absorbed, about 20% to 50% either combines with or burns down into products that are excreted within about one week in the faeces or urine. The remainder 30% to 60% of the absorbed vitamin A is stored.
