Overview

This Puritan's Pride Vitamin A supplement delivers a significant dose (2400 mcg or 8000 IU) of preformed Vitamin A (Retinyl Palmitate). This is an effective form and dose for addressing Vitamin A deficiency and supporting its various physiological roles, but it is substantially higher than the Recommended Dietary Allowance (RDA) and approaches the tolerable upper intake level (UL). While effective for its intended purpose, the high dosage necessitates careful consideration of overall Vitamin A intake from all sources to avoid toxicity.
