WHAT IT DOES
A preformed vitamin A that your body can use immediately for vision, immunity, and skin health.
🏆
2
DOES IT WORK?
Good pick. Vitamin A acetate (retinyl acetate) is a preformed, fat-soluble vitamin A. Unlike beta-carotene which needs conversion, your body uses this directly. It's critical for vision (especially night vision), immune function, and skin cell turnover. The evidence for its essential roles is rock-solid. The catch: it's fat-soluble, so it accumulates. Excess intake (especially during pregnancy) can be toxic. Stick to recommended doses.
