Vitamin A toxicity is a real risk due to its low toxic threshold. We need roughly 900 µg of it a day. However, above 3000 µg a day, we start seeing toxic effects. But you can use a smart way to avoid this potential problem.
Carotenoids such as α-carotene, ß-carotene, and ß-cryptoxanthin are the raw materials from which the body can make vitamin A.
If you consume supplements containing only these raw materials, you will not get toxicity since their toxic levels are way too high. Using these carotenoids, the body makes only that much vitamin A that it needs.
