Kaempferia parviflora (SMD: 0.46, small) was associated with a significant effect on enhancing muscular strength.
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.
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.
