Question

Why is it possible to overdose on Vitamin
A, but not on Vitamin C?

Answer 1

Answer is Vitamin C is water soluble meaning it flushes out of your system when you urinate. Vitamin A is fat soluble so it is stored in your liver and can be toxic if taken in excess.

Answer 2

Vitamin overdose occurs when a person ingests far more than the daily recommendation, for an extended period of time. Although the body can excrete excessive amounts of water-soluble vitamins such as vitamin C, it can retain fat-soluble vitamins such as vitamin A, which can be toxic.
