Product Review: Saw Palmetto Shrinks Prostate Tissue
An ancient herbal remedy for urinary problems, saw palmetto is now popular as a supplement for prostate health—and for good reason.

Saw palmetto is often the first course of therapy in men with mild to moderate prostate enlargements symptoms. The standard dosage of saw palmetto supplement of an 85%-95% extract for BPH is 320 mg per day, usually taken as 160 mg twice per day.

Other claims have seen saw palmetto treat baldness, low libido, bladder disorders, prostatitis and migraines.
Among the main constituents of saw palmetto berry extract are fatty acids and sterols, whose oily compounds are thought to have various hormonal and anti-inflammatory effects.
Saw palmetto is believed to inhibit the actions of testosterone on the prostate that cause prostate enlargement and interference with urinary problem flow. It shrinks the inner epithelium of the prostate, but not the prostate’s overall size.
While saw palmetto shows great promise for enhancing prostate health, there appears to be significant inconsistencies with the formulas available.
