Ingredient and preparation
Retinol is a preformed vitamin A form. It is distinct from provitamin A carotenoids and can add to intake from other products.
Sources: National Institutes of Health, Office of Dietary Supplements
Evidence and limits
NIH describes vitamin A’s roles in vision, immunity and normal growth. That does not establish that extra retinol improves those outcomes when intake is already adequate.
Sources: National Institutes of Health, Office of Dietary Supplements
Safety and a useful record
Preformed vitamin A can be harmful in excess, and pregnancy context is especially important. Review total intake across products with a health professional.
Sources: National Institutes of Health, Office of Dietary Supplements, National Center for Complementary and Integrative Health
