Tag: Vitamin a acetate

Scientific research confirms that vitamin A is a broad term for a family of related fat-soluble compounds, including retinoids and provitamin A carotenoids. Vitamin A acetate, conversely, is not vitamin A itself but is a stable, esterified form of it called a retinyl ester.

Supplement labels have changed from using International Units (IU) to the more precise Retinol Activity Equivalents (RAE) to account for differing bioavailabilities. To determine how much vitamin A is in vitamin A acetate, it is essential to apply the correct conversion factor.

According to the National Institutes of Health, the Tolerable Upper Intake Level (UL) for preformed vitamin A, which includes vitamin A acetate, is 3,000 mcg RAE (10,000 IU) per day for adults. Understanding how much vitamin A acetate is safe is crucial because this fat-soluble vitamin can be harmful in excessive amounts, leading to toxicity.
