Phytoecdysteroids: Distribution, Structural Diversity, Biosynthesis, Activity, and Crosstalk with Phytohormones
International journal of molecular sciences (2022) · 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.
Based on meta-analysis showing significant HAM-A score reduction (p=0.0007) and RCT evidence at 125mg dose. High heterogeneity (I2=98%) in pooled analysis suggests variable response. Extract standardization affects bioavailability.
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.
Ashwagandha has a higher evidence score (7.5/10 vs 4/10) and wins in 2 of 3 categories.
For build strength & muscle, Beta-Ecdysterone has a higher relevance score (70 vs 65).
No known interactions between Ashwagandha and Beta-Ecdysterone have been documented in our database. However, always consult a healthcare provider before combining supplements.
