Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones
International journal of molecular sciences (2022) · Systematic review
In plants, PEs play a potent role in enhancing tolerance against insects and nematodes via their allelochemical activity, which increases plant biological and metabolic responses.
Meta-analysis of 1461 subjects showed 2.85% median improvement. Effect size 0.39 overall, with optimal effects at 5.6-6.4g/day. Most effective for 1-4 minute high-intensity efforts. Side effect risk primarily reflects paresthesia (tingling), which is common but harmless.
Based on limited RCT data showing no group-specific effects in n=28 study. One small study (n=10) showed some promise but very limited sample size. Bioavailability concerns limit effectiveness estimates.
AI-estimated from published studies. Interpret as directional guidance.
Beta-Alanine has a higher evidence score (7.5/10 vs 4/10) and wins in 2 of 3 categories.
Both Beta-Alanine and Beta-Ecdysterone score equally (70) for build strength & muscle.
