Fenugreek

In a double-blinded and placebo controlled study published in the Journal of the International Society of Sports Nutrition, scientists studied how fenugreek supplementation combined with 8 weeks of resistance training would impact strength and body composition.

Subjects were healthy resistance-trained males who had not taken any ergogenic supplements for at least 6 months. They were randomly assigned to placebo or fenugreek supplementation (500 mg/day in a single dose) groups and told not to modify their diet during the 8-week study period. Subjects trained 4 days per week under the professional supervision and tested for body composition, 1RM strength, muscle endurance, and anaerobic capacity at 0 (baseline), 4, and 8 weeks into the study.

The researchers reported that all groups completed the same training volume throughout the study, but those who received fenugreek supplements had significantly increased upper and lower body strength. As well, the fenugreek group had a 2% greater decrease in body fat compared to the placebo group (who had no significant change from baseline). It was concluded that the difference in body composition observed in the fenugreek group was due to increased muscle mass. Interesting, but contrary to previous studies, the scientists found no effect of fenugreek supplementation on blood hormonal profiles (i.e., testosterone, DHT, estrogen, cortisol, insulin, leptin), suggesting that their observations were independent of hormonal or anabolic effects.
