Where you find it
BioAstin or NOW Foods algae-derived astaxanthin, similar daily dose
Consumer advice
Astaxanthin at this dose isn't snake oil, there's decent human evidence for skin and exercise-related benefits. But ignore the "9 extra years" pitch, that's an animal study dressed up as a human result. If you want to try astaxanthin, look at BioAstin or NOW Foods versions first, they deliver similar daily doses for a third to a fifth of the price. If you specifically want the "total synthesis" purity claim, ask AX3 for the actual head-to-head study data before paying the premium, and don't take dosing advice from anonymous "advocates" mentioned in the FAQ.
Claims vs Evidence
AGGRESSIVE0 of 4 claims supported by evidence. These grades score the marketing, not the product — a claim only counts as supported when the label discloses a dose that matches the studies behind it, so blends that hide doses cap at “partial” no matter how good the formula is.
