Saw Palmetto and Dihydrotestosterone (DHT)

Mechanism of Action

• Saw palmetto (Serenoa repens) acts as a natural 5-alpha-reductase inhibitor.
• It helps block the conversion of testosterone into dihydrotestosterone (DHT).

Key Physiological Effects

• Prostate Health: By reducing local DHT levels, it helps decrease the excessive stimulation of prostate tissue, which is a primary factor in benign prostatic hyperplasia (BPH).
• Urinary Symptoms: Lowering DHT activity can help alleviate common BPH symptoms such as frequent urination, weak urine flow, and incomplete bladder emptying.
• Hair Loss: Since DHT is a major contributor to androgenetic alopecia (male pattern baldness), inhibiting its production may help slow down hair thinning.

Nutritional and Clinical Considerations

• Unlike pharmaceutical 5-alpha-reductase inhibitors (like finasteride), saw palmetto generally has a much lower risk of severe side effects.
• Effectiveness can vary significantly based on product standardization, purity, and individual biochemical differences.
• It is often utilized alongside other targeted nutrients and minerals (such as zinc, pumpkin seed oil, and plant sterols) to support overall hormonal balance and prostate function.
