Saw Palmetto Extract
Reviewed by the Nimbera editorial team · Last updated May 2026
How to use
Take 320 mg of standardized liposterolic extract (85-95% fatty acids) daily, ideally with a meal to reduce GI upset. Allow 4-6 weeks for noticeable effect.
How it works
Saw palmetto inhibits 5-alpha-reductase, the enzyme that converts testosterone to dihydrotestosterone (DHT), which drives prostate cell proliferation. It also has mild anti-inflammatory and alpha-adrenergic blocking effects that relax the bladder neck.
Where to buy
Health food stores, pharmacies, Amazon - look for brands like Nature's Answer or Jarrow Formulas with standardized extract
Typical cost: $15-$35 per month
