astaxanthin — no detected effect on maximal oxygen uptake
LikelyGrade B, Likely. Human evidence, limited replication or design limits.FindingNull result“The pooled effect indicated no significant improvement in VO2max with astaxanthin supplementation compared with control (SMD = −0.14, 95% CI: −0.78 to 0.50), and heterogeneity was considerable (I2 = 83.1%).”

astaxanthin — no detected effect on interleukin-6 concentration
SuggestiveGrade C, Suggestive. Weak human evidence, or strong evidence in a mismatched population.FindingNull result“The pooled effect showed no statistically significant influence of astaxanthin supplementation on IL-6 (SMD = −0.23, 95% CI: −0.65 to 0.20), and statistical heterogeneity was absent (I2 = 0.0%).”
