What the research says
| Area | Evidence | Summary |
|---|---|---|
| Normal testosterone levels | Limited | Fenugreek has been studied for supporting normal testosterone levels. A 2026 review of placebo-controlled trials found a small rise in total testosterone but no clear change in free testosterone, and rated the certainty very low.[2] |
| Muscle strength | Limited | A 2023 review of 7 studies in mostly male athletes found small changes in leg press strength and lean mass, but none were statistically clear.[3] |
Questions
When should I take fenugreek?
No study has tested the best time of day. Trials gave it every day, so choose a time you will remember.
How long does fenugreek take to work?
Most trials lasted 8 to 12 weeks. There is no good evidence on effects in a shorter time.
Can I take fenugreek while breastfeeding?
Studies on whether it helps milk supply have mixed results. Little is known about its safety in amounts larger than food, so ask your doctor first.
Can women take fenugreek?
Do not take it in supplement amounts while pregnant. Most testosterone studies were done in men, and one review said no conclusions can be drawn for female athletes.
