Frequently Asked Questions

Does fenugreek really increase testosterone?

Multiple RCTs show that standardized fenugreek extract (particularly Testofen) can increase free testosterone levels in men. The mechanism appears to involve inhibition of aromatase and 5-alpha-reductase, which reduces the conversion of testosterone to estrogen and DHT. The effect is most pronounced with standardized extracts at 500-600mg daily over 8-12 weeks. Whole seed powder has not been well-studied for testosterone specifically.

Why does fenugreek make my sweat smell like maple syrup?

Fenugreek contains sotolon, a compound that has a strong maple syrup-like aroma. When consumed in supplement quantities, sotolon is excreted through sweat and urine, creating a noticeable sweet odor. This is completely harmless and is actually used diagnostically — sotolon is the same compound responsible for the odor in maple syrup urine disease. The effect is dose-dependent and resolves when supplementation stops.

Can I take fenugreek if I have diabetes?

Fenugreek has well-documented blood sugar-lowering effects and is used traditionally for glycemic management. However, if you are on diabetes medications (metformin, insulin, sulfonylureas), fenugreek can cause additive hypoglycemia. Always consult your endocrinologist before adding fenugreek, start at a low dose, and monitor blood sugar closely. The fiber-rich whole seed form has the strongest glycemic effects.
