What is the recommended dosage for Fenugreek?

General: 500-600 mg/day seed extract (standardized to 50% saponins)

What are the side effects of Fenugreek?

Potential side effects include: Gastrointestinal discomfort (bloating, diarrhea), Maple syrup odor in sweat and urine, Allergic reactions in individuals with peanut/chickpea allergies (cross-reactivity), May increase appetite.

Is fenugreek effective for hair loss?

Fenugreek (Trigonella foenum-graecum) seeds contain compounds that may support hair health through multiple mechanisms: phytoestrogens may modulate hormonal pathways, proteins and nicotinic acid may nourish hair follicles, and lecithin may support moisture retention. Small clinical studies suggest potential benefits for hair density and thickness, but larger trials are needed. Consult your healthcare provider.

What is the typical fenugreek dosage used in hair studies?

Most clinical research on fenugreek for hair and hormonal outcomes uses 300–600 mg of standardized seed extract daily, often split into two doses with meals. A 6-month study involving 53 participants found that a daily fenugreek supplement was associated with improved self-reported hair density and reduced hair loss compared to baseline. Fenugreek seeds can also be used as a topical paste in some traditional practices, though clinical evidence is stronger for oral supplementation. The herb has a generally good safety profile at studied doses; mild digestive discomfort is the most commonly reported side effect.

How might fenugreek help with DHT-related hair thinning?

Fenugreek contains steroidal saponins, including diosgenin and gitogenin, which may influence androgen metabolism relevant to androgenetic alopecia. Research suggests these compounds may modulate 5-alpha reductase activity, the enzyme that converts testosterone to the more potent DHT that shrinks hair follicles over time. Fenugreek also contains phytoestrogens that may help balance androgen-to-estrogen ratios in a modest way. Human trials specifically measuring DHT levels alongside hair outcomes are limited, so fenugreek is generally considered a complementary option rather than a primary DHT blocker. Consult your healthcare provider for evaluation.

About

Fenugreek (Trigonella foenum-graecum) seeds contain furostanol saponins that may inhibit 5-alpha-reductase activity. A small number of clinical studies suggest fenugreek extract may support hair density and reduce self-reported hair thinning, though larger trials are needed to confirm these preliminary findings.

How It Works

Furostanol saponins (e.g., protodioscin) inhibit 5-alpha-reductase; phytoestrogens may modulate hormonal balance; rich in protein and nicotinic acid for follicle nutrition.
