What is it
Fenugreek (Trigonella foenum-graecum) is a small annual plant whose seeds and leaves are used as a culinary spice and herbal medicine. Originating in the Mediterranean and Middle East, it has been used traditionally for blood glucose support, breastfeeding, and male sexual health.

Evidence for 4 uses
AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.
type 2 diabetes glucose support
Biomarker supportSmall trials and meta-analyses of seed preparations report modest reductions in fasting glucose and HbA1c, attributed largely to the soluble galactomannan fiber slowing carbohydrate absorption. Study quality and dosing forms vary widely, so effect estimates are uncertain. This is a glucose-marker effect, not demonstrated diabetes complication prevention.
Bottom line: May modestly improve glucose markers in type 2 diabetes, but evidence is limited and product-dependent.
male sexual function and testosterone
Biomarker supportSeveral small RCTs of standardized fenugreek seed extracts report modest improvements in self-reported sexual function and small changes in testosterone or free testosterone. Results are tied to particular branded products and have not been consistently replicated. Testosterone is a biomarker; trials do not establish fertility or clinical hypogonadism benefit.
Bottom line: Some standardized extracts modestly shift testosterone and self-reported libido, but the evidence is small and product-specific.
Evidence is mixed
Positive findings cluster around specific commercial extracts; independent replication and effects on hard fertility endpoints are lacking.
lactation milk supply
Supplement benefitFenugreek is a long-standing traditional galactagogue, and some small trials suggest increased milk volume, but results are mixed and trials are low quality. The mechanism is uncertain. Infant exposure through milk has not been well characterized.
Bottom line: A traditional milk-supply aid with weak, inconsistent evidence.
Evidence is mixed
Some small trials show increased milk output while others show no benefit over placebo; methodology is generally weak.
cholesterol and lipids
Biomarker supportSome small trials of larger seed doses report reductions in total and LDL cholesterol, plausibly through fiber-mediated effects on cholesterol absorption. Trials are small and heterogeneous. This is a lipid-marker effect with no cardiovascular outcome data.
Bottom line: May modestly lower cholesterol markers at higher seed doses, on weak evidence.

Frequently asked questions
Does fenugreek really increase milk supply?⌄
Some trials suggest modest benefit, and it is commonly recommended by lactation consultants. Evidence is mixed, and not all women respond. Discuss with a lactation specialist for individualized recommendations.
Why do I smell like maple syrup?⌄
Fenugreek contains sotolon, a compound responsible for its characteristic maple-syrup-like aroma. At higher doses, this can affect body odor, sweat, and urine. The effect is harmless and reverses on stopping.
Is fenugreek safe in pregnancy?⌄
No. Avoid fenugreek in pregnancy due to potential uterine effects and traditional use as a labor-inducing herb. Culinary amounts in food are generally fine.
Can fenugreek lower blood sugar?⌄
Some trials suggest modest blood-glucose-lowering effects, particularly in people with type 2 diabetes. Effects are smaller than standard medications. Monitor closely if you take insulin or oral diabetes drugs.
Will fenugreek boost testosterone?⌄
Some standardized seed extracts have shown modest free testosterone increases in trials. Effects are smaller than reported for prescription therapies, and benefits vary.
