Product Overview
Vitamin A (Retinyl Palmitate) is the most stable esterified form of Vitamin A used in pharmaceutical multivitamin formulations, nutritional supplements, and topical skin preparations. It is essential for vision, immune function, skin integrity, and cell differentiation. Retinyl Palmitate is preferred over retinol in formulations due to its greater stability under processing and storage conditions.

What is the difference between Retinyl Palmitate, Retinyl Acetate, and Retinol as Vitamin A sources?
All three provide preformed Vitamin A (retinol) but differ in stability and application. Retinyl Palmitate (most stable, highest MW) is preferred in solid dosage forms and cosmetics for its long shelf life and good oil compatibility. Retinyl Acetate is more potent per gram (500,000 IU/g vs ~300,000 IU/g for Palmitate) but less stable. Retinol is the biologically active alcohol form — most potent but highly unstable and rapidly oxidised. For pharmaceutical formulations and cosmetics, Retinyl Palmitate is the industry standard due to its superior stability.
What is the safe upper limit for Vitamin A supplementation to avoid toxicity?
Vitamin A is a fat-soluble vitamin that accumulates in the liver, making toxicity a genuine concern at high doses. The tolerable upper intake level (UL) is 3,000 mcg RAE/day (10,000 IU/day) for adults. Chronic intake above this level causes hypervitaminosis A — headache, bone pain, liver damage, and teratogenicity. Pregnant women must be particularly careful: doses above 3,000 mcg RAE/day in the first trimester are teratogenic. Standard multivitamins contain 700–900 mcg RAE (2,300–3,000 IU) Vitamin A, well within safe limits.
Why is Beta-Carotene sometimes used instead of Retinyl Palmitate in supplements?
Beta-Carotene is a provitamin A carotenoid converted to retinol in the intestinal wall on an as-needed basis. Because conversion is regulated by the body's Vitamin A status, Beta-Carotene does not cause hypervitaminosis A even at high doses — making it a safer choice for formulations targeting populations at risk of deficiency without the teratogenicity concern. However, its bioavailability is lower and variable. For clinical deficiency treatment where precise Vitamin A delivery is needed, Retinyl Palmitate is preferred. For general multivitamin formulations where safety margin is a priority, Beta-Carotene is increasingly used.
