  I’m not a nutritionist, but I know for a fact vitamin a, among others, is not made by plants. I think people should probably just talk to their health care professionals. strangers on the Internet need have no credentials, and often have motivated reasoning.

    Humans synthesize Vitamin A from Beta Carotene in plants. Only a small minority of people who are genetically predisposed to less efficient conversion of Beta Carotene would need to supplement with the retinyl form (readily available in supplements)

    Per the NIH:

    The human diet contains two sources for vitamin A: preformed vitamin A (retinol and retinyl esters) and provitamin A carotenoids [1,5]. Preformed vitamin A is found in foods from animal sources, including dairy products, eggs, fish, and organ meats [1,2]. Provitamin A carotenoids are plant pigments that include beta-carotene, alpha-carotene, and beta-cryptoxanthin [1]. The body converts provitamin A carotenoids into vitamin A in the intestine via the beta-carotene monooxygenase type 1 BCMO1 enzyme [1,3,6], although conversion rates may have genetic variability

    You can get vitamin A from carrots. That’s one of the reasons the British beat the Germans.
