Please tell me how long it takes for the body to flush excess vitamin a?
A doctor has provided 1 answer
Depends: Acute toxicity occurs when adults take more than 20-100 times the rda ( recommended daily amount) of vitamin a over a period of hours or a few days. This clears in days. This is less of a problem than is chronic toxicity from preformed vitamin a. Chronic toxicity results from the taking high amounts of preformed vitamin a for months or years of > 25, 000 iu can lead to permanent health problems.
