Vitamin A

Vitamin A is a Vitamin supplement available in 3 forms.

Not all forms of Vitamin A are equal. The form you choose determines how much Vitamin A actually reaches your tissues, and the difference between the best and worst forms can be substantial. Mixed carotenoids provide a full spectrum of provitamin A compounds that the body converts to retinol on demand, virtually eliminating hypervitaminosis A risk. Single-compound beta-carotene supplementation has shown concerning results in some populations, while the mixed carotenoid approach mimics natural dietary intake and provides broader antioxidant coverage.

Vitamin A (Mixed Carotenoids) Preferred (T1 Preferred) has a bioavailability rating of good (S2). Typical dose range: not yet documented in our database.

Vitamin A (as Beta Carotene) (T2 Specialist) has a bioavailability rating of good (S2). Typical dose range: not yet documented in our database.

Vitamin A (as Vitamin A Palmitate) (T2 Specialist) has a bioavailability rating of moderate (S3). Typical dose range: not yet documented in our database.

Mixed carotenoids provide a spectrum of provitamin A carotenoids (alpha-carotene, beta-carotene, lutein, zeaxanthin, cryptoxanthin) that the body converts to retinol as needed, reducing the risk of hypervitaminosis A. Research indicates mixed carotenoid supplementation provides broader antioxidant coverage than single-carotenoid forms. This approach mimics the natural dietary intake pattern from fruits and vegetables.

Vitamin A (Mixed Carotenoids) is classified as T1 Preferred in the FormulaForge formulary — our top recommendation for Vitamin A. It carries a bioavailability rating of good (S2), meaning more of the active compound reaches your tissues per dose unit compared to lower-tier forms.

When choosing a Vitamin A supplement, look for the S1 (best absorption) bioavailability tier on the label or formulary listing. T1 Preferred forms have the strongest research-backed evidence for efficient absorption.

Other forms may be appropriate depending on individual goals, cost considerations, and your healthcare provider’s guidance. The best form for you depends on your specific health needs.
