Saw Palmetto and Prostate Health: What the Research Shows
Saw Palmetto is the most recognizable name in men's prostate supplements, and for good reason — it's also one of the most studied. Here's what the research actually supports.
What it is
Saw Palmetto is an extract from the fruit of Serenoa repens, a small palm native to the southeastern United States. Extracts are typically standardized to a percentage of fatty acids and sterols.
How it's thought to work
The leading theory is that Saw Palmetto helps support healthy levels of dihydrotestosterone (DHT) activity in prostate tissue. DHT accumulation is associated with prostate enlargement and related urinary difficulties in aging men.
What the evidence shows
Multiple clinical trials have studied Saw Palmetto for urinary symptom support, with mixed but generally favorable results for mild-to-moderate symptoms. As with most botanical research, results vary by study design, dose, and extraction method, and findings on the ingredient don't automatically transfer to any specific finished product.
