Saw Palmetto

Saw palmetto is an extract from the berries of Serenoa repens, a small palm native to the southeastern United States. Native American tribes used the berries as food and medicine for urinary and reproductive issues for centuries.

The active compounds are primarily fatty acids and plant sterols, with most supplements standardized to contain 85-95% fatty acids. The proposed mechanism involves inhibiting 5-alpha reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT), which drives prostate enlargement.

Saw palmetto is generally well-tolerated with a favorable safety profile. Most common side effects include mild stomach upset, nausea, or diarrhea when taken on an empty stomach. Rare reports include decreased libido, though this is uncommon and usually reversible. Unlike prescription medications for BPH, saw palmetto doesn't typically cause sexual dysfunction or dizziness.

• Anticoagulants (warfarin, aspirin) - May enhance blood-thinning effects • Hormone replacement therapy - Theoretical interaction due to hormonal effects • Finasteride/dutasteride - May have additive effects, though combination studies are limited

Standard dose: 320mg daily of standardized extract (85-95% fatty acids)

Timing: With food to minimize stomach upset, preferably at the same time daily

Duration: Benefits typically emerge after 1-3 months of consistent use. Most studies evaluate 6-12 months of treatment.

Saw palmetto supplements typically cost $8-15 monthly for quality standardized extracts. Basic formulations start around $5-8, while premium standardized extracts with third-party testing range $12-20. Combination formulas with other prostate nutrients cost $15-30 monthly.
