Micellized Vitamin A from Klaire Labs/SFI Health is a liquid vitamin A supplement that uses micellization technology to deliver retinol in water-dispersible micro-droplets, supporting immune function, skin integrity, and healthy vision. Designed for individuals who may have difficulty absorbing fat-soluble nutrients, this form is particularly relevant for those with compromised digestive or lipid metabolism.
Why It's Worth Considering: Micellized delivery enhances the absorption of fat-soluble vitamin A without requiring dietary fat co-ingestion, making it a practical option for sensitive or compromised GI tracts — a consideration well-recognized in practitioner-grade clinical settings.
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.
