12 mg Astaxanthin for 28 Days: Muscle Damage and Burnout in Fighters
A new randomized trial put 12 mg of daily astaxanthin to the test in young male taekwondo athletes. After 28 days, the supplement group showed a significantly different creatine kinase trajectory than placebo, plus higher SOD and exploratory signs of lower MDA and less emotional and physical exhaustion. But the burnout findings were exploratory, with no group × time interaction on any subscale. The trial was small and measured biomarkers, not performance. Here's what the data show, what they don't, and who might want to pay attention.
Astaxanthin for 4 Days Boosted Cycling Time-to-Exhaustion From 72 to 85 Minutes in a Small Trial
Four days of astaxanthin at 28 mg/day lengthened cycling time to exhaustion from about 72 to 85 minutes in a small randomized trial, a gain of roughly 18%. The same protocol blunted rises in muscle damage markers (CK and LDH) and lipid peroxidation (MDA) after a hard ride at 75% VO2max. Inflammation markers and fuel use did not change, so the mechanism is still unclear. The dose is also well above what many softgels provide, and the study had just ten young men. Here is what the numbers show and where the evidence stops.
