Recommended Intake and Dosage

The Recommended Dietary Allowance (RDA) for vitamin A varies by age and gender. For adult men, the RDA is 900 mcg RAE (3,000 IU); for women, it is 700 mcg RAE (2,333 IU). Needs increase during pregnancy and lactation. The Tolerable Upper Intake Level (UL) for adults is 3,000 mcg RAE (10,000 IU) of preformed vitamin A. NOW Foods Vitamin A 25000 IU delivers 25,000 IU (7,500 mcg RAE) per softgel, which exceeds the UL for daily intake. This product is intended for short-term use or under medical supervision. Always consult a healthcare professional before taking high-dose vitamin A.

Types of Vitamin A: Retinol vs. Beta-Carotene

Vitamin A occurs in two principal forms with distinct characteristics. Retinol (preformed vitamin A) from animal sources is directly usable by the body. Beta-carotene, a provitamin A carotenoid, must be converted into retinol, and conversion efficiency varies among individuals. NOW Foods Vitamin A uses retinyl palmitate, a stable, highly bioavailable form of preformed vitamin A. This ensures consistent potency and absorption without reliance on conversion.

Vitamin A Benefits

Vitamin A supports several key functions in the body. Here are some of its most recognized benefits:

• Vision Support: Vitamin A is a component of rhodopsin, essential for low-light and colour vision. Adequate intake helps maintain normal eyesight and dark adaptation.
• Immune Function: This nutrient helps maintain mucous membrane integrity and supports white blood cell production and activity, contributing to a healthy immune response.
• Skin Health: Vitamin A promotes cell growth and differentiation, helping to keep skin and mucous membranes healthy and resilient.
• Antioxidant Activity: As part of the body's antioxidant defense system, vitamin A helps neutralize free radicals that can cause cellular damage.

NOW Foods Vitamin A 25000 IU provides a concentrated source to help you meet your daily needs.
