Fenugreek Boosts Testosterone

Bodybuilders who take 500 mg fenugreek extract daily increase the amount of bio-available testosterone in their blood, write sports scientists at the University of Mary Hardin-Baylor in the International Journal of Sport Nutrition and Exercise Metabolism. Their study suggests that fenugreek has an anti-oestrogenic effect.

Animal and human studies have shown that fenugreek has a mild anabolic effect. According to the sponsor of these studies, the Indian Indus Biotech, this is because fenugreek boosts testosterone levels, but the studies don’t actually provide proof of this.

But then there’s the study that this posting is about. It was published in 2010, and was done by a respected group of researchers in the US. Thirty young strength athletes, average 21, were the test subjects for this study.

Half of them took a daily 500 mg fenugreek extract [AI] for eight weeks. The extract was produced by Indus Biotech, in this case also the sponsor of the study. The extract was standardised for graecunins, a group of steroid-like compounds – spirostanes to be exact – found in fenugreek.

The other half of the group were given a placebo [PL].

In the eight weeks that the study lasted, both groups increased their strength by about the same amount. T1= week 0, T2 = week 4; T3 = week 8.
