Size: 100 Softgel Capsules
NOW Foods Vitamin A 25,000 IU delivers preformed retinol in a softgel capsule, a fat-soluble form that supports vision, immune function, and skin cell turnover. At 25,000 IU per serving, this is a higher-potency option suited for adults working with a healthcare provider to address specific nutritional needs.
Why It's Worth Considering: Softgel delivery improves absorption of this fat-soluble vitamin compared to dry tablet forms, and NOW Foods maintains consistent third-party testing across its product line.
Preformed vitamin A (retinol/retinyl palmitate) is immediately active — your body uses it directly. Beta-carotene is a provitamin A that must be converted to retinol. Conversion is inefficient (6:1 ratio) and varies by genetics — up to 45% of people are poor converters. For therapeutic use, preformed retinol or retinyl palmitate is preferred.
The tolerable upper limit is 10,000 IU/day of preformed vitamin A for adults. Most supplements provide 3,000-5,000 IU. Cod liver oil provides natural vitamin A + D together. Beta-carotene does not have a toxic upper limit (excess is stored harmlessly). Pregnant women should not exceed 5,000 IU preformed A.
Yes — vitamin A is fat-soluble and accumulates in the liver. Chronic intake above 25,000 IU/day can cause toxicity (headache, nausea, liver damage, bone loss). This is only a concern with preformed vitamin A supplements, not beta-carotene or food sources. Stay within recommended doses and avoid combining multiple A-containing supplements.
