Published in Biological Research for Nursing
Methodology
Random-effects meta-analysis with meta-regression of 11 RCTs in healthy participants
Key Findings
Cognitive accuracy effect only marginally significant (SMD 0.12, CI -0.02 to 0.26) and reaction time not significant (SMD -0.08). Physical performance improved (SMD 0.62) and fat oxidation increased (SMD 2.56), with greater benefit at doses >=20 mg and durations >12 weeks.
Conclusions
Astaxanthin improves aerobic exercise efficiency at higher doses but shows no clear cognitive benefit.
Limitations
Small healthy-volunteer samples; few trials per endpoint; heterogeneous outcome measures.
Supplements Studied
astaxanthin supplementation could significantly enhance aerobic exercise efficiency, especially at higher doses and for longer durations
Outcomes Measured
The effects of astaxanthin supplementation for 8-12 weeks on cognitive accuracy were marginally significant and on reaction time was not significant
