Evidence Level
Fenugreek is a well-researched supplement offering notable benefits for men's health and glycemic control. A 2016 double-blind RCT by Rao et al. demonstrated that Testofen, a specialized fenugreek extract, significantly improved sexual function and increased free testosterone levels in healthy males aged 25-52 after 12 weeks of supplementation (Rao et al., 2016). Similarly, Wankhede et al. (2016) found that 500mg of fenugreek extract daily for eight weeks enhanced testosterone levels and reduced body fat percentage in resistance-trained men (Wankhede et al., 2016). Additionally, Poole et al. (2010) reported improved strength training outcomes with fenugreek supplementation in a placebo-controlled trial.
Regarding glycemic benefits, Neelakantan et al. (2014) conducted a meta-analysis of 10 trials confirming significant reductions in fasting glucose and HbA1c levels with fenugreek intake (Neelakantan et al., 2014). More recent studies support these findings: Shabil et al. (2023) analyzed 14 trials involving 894 participants, showing that fenugreek significantly lowers HbA1c but has no significant effect on fasting or postprandial blood glucose (Shabil et al., 2023). Kim et al. (2023) reviewed 10 RCTs and found that fenugreek reduces fasting blood glucose, 2-hour post-glucose plasma glucose, and HbA1c in individuals with type 2 diabetes or prediabetes (Kim et al., 2023). These studies collectively highlight fenugreek's role in supporting male health and managing glycemic control.
