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 ar­ti­cle 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. The lean body mass in­creased in both the placebo group and the ex­per­i­men­tal group by 1.6 kg. The amount of bio-avail­able testos­terone in­creased by 26 per­cent in the ex­per­i­men­tal (Fenu­greek) group. The estra­diol lev­els did not in­crease by this much, al­though you might have ex­pected that to hap­pen. Ap­par­ently Fenu­greek ex­tract in­hibits the con­ver­sion of testos­terone into estra­diol. The study showed the per­cent­age de­crease of fat mass in the test sub­jects. The fat per­cent­age of the ath­letes in the fenu­greek group fell from 18.9 to 17.1 per­cent. In the placebo group the de­crease was from 18.4 to 17.8 per­cent. Fenu­greek proves to be a wor­thy ad­di­tion to any nat­u­ral ath­letes sup­ple­ment pro­gram. Just look for fenu­greek that has higher saponins level.
