Saw palmetto and prostate health
Saw palmetto is one of the best-known botanical ingredients in prostate supplements. Popularity, however, is not the same thing as demonstrated clinical benefit.
What NCCIH says
NCCIH reports that many studies have examined saw palmetto for urinary tract symptoms associated with prostate enlargement. Its current consumer summary concludes that saw palmetto alone probably is not helpful for this purpose; a 2023 review found little or no benefit for BPH symptoms.
Safety
NCCIH describes saw palmetto as generally well tolerated in research, with mild and infrequent adverse effects such as digestive symptoms, dizziness and headache. Individual circumstances and medication use still matter.
What this means for a multi-ingredient product
Evidence about saw palmetto alone cannot establish whether a finished multi-ingredient supplement works. If you're researching Prosta Peak, see our ingredient analysis and full review.
