Ursolic Acid-induced Elevation Of Serum Irisin Augments Muscle Strength During Resistance Training In Men

Effect Increase
Trial Design Double blind
Trial Length 1-6 months
Number of Subjects 16
Sex Male
Age Range 18-29, 30-44
Body Types Trained, Average
Notes for this study:
450mg of ursolic acid (from rosemary) in three divided doses of 150mg with meals over the course of 8 weeks, in subjects who were physically training (and had a history of training), did not appear to modify body composition more than placebo but increased serum irisin (12%) and IGF-1 (22.8%) more than placebo.

Strength (power output isokinetically at peak torque) was increased more with ursolic acid than it was with placebo.
