Hayley,

Here are two articles from the Linus Pauling Institute that you might find helpful:

https://lpi.oregonstate.edu/mic/dietary-factors/phytochemicals/carotenoids
https://lpi.oregonstate.edu/mic/vitamins/vitamin-A#safety

The amount of beta-carotene and vitamin A in multivitamins are typically measured in micrograms whereas the amounts in clinical trials that have shown harmful effects are measured in milligrams and tend to be much higher. So, I wouldn’t be worried about the amounts in multivitamins though I wouldn’t take high-dose beta-carotene or vitamin A supplements.

Sounds like you might have had some kind of extreme absorption impairment or some other underlying condition.

Within 1 year of no supplementation we became severely deficient in vitamin A and developed eye, skin, and immune issues. This was in spite of drinking 1 cup of carrot juice a day, 200 grams sweet potato, 100 grams cantaloupe, and eating a wide variety of greens, in addition to including a modest (10 grams) of fat with each meal to aid absorption. Supplements did raise our levels, but without at least 900 mcg daily, the levels begin to fall. Vitamin A is definitely overlooked so I appreciate bringing this issue to light.

Vitamin A levels in vegans are discussed in the β-carotene and Vitamin A section of our article Bone Fractures among U.K. Vegans: Implications and Recommendations.

Correct. As stated in this article, retinol is preformed vitamin A (found in animal-based foods). Plant foods contain carotenoids which the body converts to vitamin A. As stated in this article, 1 IU beta-carotene from foods is equivalent to 0.05 mcg RAE and 1 IU beta-carotene from dietary supplements is equivalent to 0.15 micrograms RAE.
