This product’s label dose is one 12 mg softgel daily, taken with a meal that contains fat for absorption. That sits at the upper end of the 4–12 mg/day range most commonly used in astaxanthin research.
A randomized, double-blind, placebo-controlled trial in healthy adults used a lower dose — 4 mg/day for 10 weeks — and found measurable protection against UV-induced skin deterioration versus placebo [1]. That trial’s 4 mg dose is a third of this product’s 12 mg label dose, so it’s included here as supporting context for the broader studied range, not a claim that this specific product has been trialed at its own dose.
As with the other calculators on our network, there’s no published bodyweight-adjusted dosing for astaxanthin, so this tool plans by a fixed daily amount rather than your height or weight.
