      Just a couple article shares here, that I found interesting in my research, on Fenugreek


      Fenugreek (Trigonella foenum-graecum) is a plant from Fabeaceae family which is used for many medical plans. Fenugreek is used in may cuisines either as a herb, as a spice, or as a vegetable. Fenugreek also has many pharmacological effects and is lately very popular in the bodybuilding world.


      Possible Fenugreek Uses (Is it Really Anabolic?)


      Hormonal Interaction


      Bushey, Brandon, et al. [7] conducted a study, supported by Indus Biotech, on forty-five resistance-trained males, who were given either 500 mg of fenugreek extract or placebo. There were no changes in the metabolic hormones insulin, cortisol or leptin. No significant effects for groups were observed for the anabolic hormones free testosterone and estrogen (p<0.05). However, supplementation of fenugreek extract resulted in a decrease in serum dihydrotestosterone (DHT) levels (-9.42%) in comparison to placebo. Other anabolic and metabolic hormone analyses were not affected by supplementation.


      Another study [12] evaluating fenugreek as 5α-reductase inhibitor failed to affect dihydrotestosterone (non-significant increase) levels. However, the group receiving 500 mg of fenugreek daily significantly increased total testosterone (6.57%) and bioavailable testosterone (12.26%). Because of this significant increase in total and free testosterone without a corresponding increase in DHT and estradiol, fenugreek appears to inhibit (but incompletely) aromatase and 5α-reductase activity.


      One very recent study [10] carried out in the Centre for Integrative Clinical and Molecular Medicine has found that 60 men aged between 25 and 52 who took a fenugreek extract twice daily for six weeks showed an overall positive effect on physiological aspects of libido (sexual drive or desire for sexual activity). Serum prolactin and testosterone levels remained within the reference range.


      Though fenugreek is, by some companies, marketed and sold as »testosterone booster«, most studies do not support this claim. It does seem to be a weak 5α-reductase inhibitor.

      Effects on Body Composition


      Researchers have shown that diabetic mice which were cured by seed extract of fenugreek seeds, had an increase in weight [1]. The effect of fenugreek on a fat index of diabetic patients with high cholesterol showed that this plant reduced fats significantly [3]. Fenugreek does seem to have positive effects on body composition in combination with resistance training by decreasing body fat percentage [8,12] but its consumption can actually increase estrogen levels [2,9] and can potentially cause gynecomastia (male breast growth). Wilborn et al. [12] reported no significant changes in body mass or lean mass but fat mass decreased significantly in fenugreek supplemented group.

      Other Fenugreek Uses


      Fenugreek also serves as prolactin stimulator [2] because it contains galactagogue that increases lactation, and has been successfully used for nursing mothers (it may increase mothers milk supply) [4]. Furthermore, fenugreek is a good source of amino acid 4-Hydroxyisoleucine which is known for its anti-diabetic properties [5-6].


      Fenugreek Dosage


      Studies evaluating fenugreek for its purported anabolic effects typically use doses ranging between 500-600 mg.


      Fenugreek Side Effects


      According to WebMD.com [11]: “Fenugreek is likely safe for people when taken by mouth in amounts normally found in foods. It is possibly safe when taken in amounts used for medicinal purposes.” Some of the fenugreek side effects include diarrhea, stomach upset, bloating and gas. Fenugreek might lower blood sugar [11]. Fenugreek can also potentially cause gynecomastia. No side effects were reported by any of the participants in Wilborn et al. [12] study. One study using 3g/kg bodyweight of fenugreek also reported no adverse effects [13].
