Fenugreek Seed Extract

Reviewed by the Nimbera editorial team · Last updated May 2026

A meta-analysis confirmed fenugreek extract significantly increases total serum testosterone in men, with a randomized double-blind trial in 95 men showing plasma total and free testosterone index increased at all doses versus placebo.$15-$30 per month

How to use

Take 400-600 mg of standardized fenugreek seed extract daily, ideally with meals. Most trials last 8-12 weeks. Look for extracts standardized to furostanolic saponins.

How it works

Fenugreek contains furostanolic saponins (including protodioscin) that are thought to inhibit enzymes (5-alpha reductase and aromatase) that convert testosterone to dihydrotestosterone and estrogen, thereby preserving free testosterone levels.

Where to buy

Health food stores, iHerb, Amazon - look for standardized extract products (Testofen is a commonly studied branded form).

Typical cost: $15-$30 per month
