Does Astaxanthin Visual Performance Randomized Trial work?

The current Migaku evidence database contains 2 reusable source documents for Astaxanthin Visual Performance Randomized Trial. This answer focuses on strength of evidence and what the studies can or cannot prove. - Astaxanthin significantly reduced creatine kinase levels (SMD = -0.45, 95% CI: -0.83 to -0.07). [Liu S (2026); evidence level 1] - Conclusions : Current evidence suggests that astaxanthin may be more beneficial for post-exercise recovery than for direct performance enhancement. [Liu S (2026); evidence level 1] - Background : Astaxanthin is a lipid-soluble carotenoid with antioxidant and anti-inflammatory properties, but its effects on exercise performance and post-exercise recovery remain uncertain. [Liu S (2026); evidence level 1] - This systematic review and meta-analysis aimed to evaluate the effects of astaxanthin supplementation on exercise performance and recovery-related biomarkers in healthy participants and athletes. [Liu S (2026); evidence level 1] - It is imperative to develop a sustainable food system with a reduced environmental footprint [,,]. [Zhang Xiaomei (2026); evidence level 3] Evidence levels are sorting aids, not final clinical grades. Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational.
