Vitamin A – How Much is Too Much?

Dr, how much is too much vitamin a. I take supplements and a few of them have large amounts of vitamin a like 5000 iu of vit. a.

For most people, up to 25,000 IU (7,500 mcg) of vitamin A per day is considered by some authorities to be safe, but the Food and Drug Administration has established a daily recommended allowance (RDA) of 5,000 IU for vitamin A. Toxicity in the fetus of pregnant women may occur in doses above 10,000 IU. A complete analysis of vitamin A is presented in Solgar Healthnotes.

The dose should be adjusted for pregnant women and children and a doctor should be involved in that. If vitamin A is being used for treatment of vitamin A deficiency, higher doses are required and it should be done under a doctor’s supervision. Complications (overdose) include liver damage, hair loss, blurred vision, and headaches. Sound like you are in the normal dose range.
