Vitamin A source

Vitamin A toxicity

To avoid hypervitaminosis A, avoid taking more than the recommended daily allowance of this vitamin. Recent emphasis on vitamin A and beta carotene as anti-cancer vitamins may contribute to chronic hypervitaminosis A, if well-meaning people increase the dosage of vitamins beyond recommended values. More is not always better!
