Synopsis

Source of validity: Scientific
Rating (out of 5): 4

Several types of berries have been studied for their effects on prostate health, but the most prominent is saw palmetto berry (Serenoa repens). Saw palmetto has a long tradition of use for urinary and prostate health, especially in managing symptoms of benign prostatic hyperplasia (BPH), a non-cancerous enlargement of the prostate that affects many older men. Clinical studies, including randomized controlled trials and meta-analyses, have investigated saw palmetto extract for its ability to reduce lower urinary tract symptoms associated with BPH. While some studies report modest improvements in urinary flow and symptom scores, others find little to no benefit compared to placebo. The evidence is mixed, but there is a substantial body of scientific literature supporting its use, albeit with some controversy regarding the magnitude of effect.

Other berries, such as cranberries and pomegranates, have also been studied for their potential to support prostate health due to their high content of antioxidants and anti-inflammatory compounds. Some laboratory and animal studies suggest that polyphenols from these berries may help protect prostate cells from oxidative damage and may slow the progression of prostate cancer, but clinical evidence in humans remains limited and inconclusive.

Overall, the use of certain berries, especially saw palmetto, to support the prostate is justified by both tradition and scientific investigation, with the most robust evidence available for saw palmetto in managing BPH symptoms. The overall evidence rating is 4 out of 5, primarily due to the extensive research specifically on saw palmetto berries.
