Retinyl acetate (retinol acetate, vitamin A acetate) is a natural[dubious – discuss] form of vitamin A which is the acetate esterofretinol. It has potential antineoplastic and chemopreventive activities.[2][3]
In the United States, retinyl acetate is classified generally recognized as safe (GRAS) in the amounts used to fortify foods with vitamin A.[4][5]
World Health Organization "Recommendations for preformed vitamin A supplements for mothers during pregnancy" states that "health benefits are expected for the mother and her developing fetus with little risk of detriment to either, from a daily supplement not exceeding 10,000 IU vitamin A (3000mcg RE) at any time during pregnancy." Preformed Vitamin A refers to retinol and retinyl esters, such as retinyl palmitate and retinyl acetate.[6]
