Vitamin A in the digestive tract, the stomach in almost not be absorbed, in the small intestine and bile acid fat decomposition product together was emulsified by intestinal mucous membrane absorption. Vitamin A human body storage with age increasing, to old age is obviously lower than young people, different gender storage also different. Vitamin A in the body average half life for 128 ~ 154 days, in the absence of vitamin A intake, daily hepatic loss (catabolism) rate is about 0.5%.
