Explain the Storage of vitamin A?

The primary organ for storage of vitamin A is the liver. Reserves are found in the stellate cells, as mentioned above. The average liver weighs 1.5 kg and when replete, contains 450 mg of vitamin A stores. Hepatic tissue concentrations of < 30 mcg /g is considered marginal. Total body stores of vitamin A range from 300-900 mg with 20% found in peripheral organs and tissues. So far we have discussed about the absorption, transport, storage of vitamin A. It was mentioned in the text above that the bioavailability of vitamin A is a determinant of its absorption and hence excretion. Let us now understand the key aspects related to the bioavailability of vitamin A.
