Saw palmetto appears in products marketed for prostate and urinary concerns. If you have seen it on a label, the useful question is whether the evidence supports the reason you are considering it.
What is saw palmetto?
Saw palmetto is a small palm whose berries are used in herbal products. It is often promoted for urinary symptoms associated with an enlarged prostate. NCCIH — Saw palmetto.
Promotion and clinical evidence are different things. The US National Institutes of Health summary reports that a 2023 review of 27 studies found little or no benefit from saw palmetto alone for symptoms associated with benign prostate enlargement. Evidence for combinations was less clear. NCCIH — Saw palmetto.
That finding does not support the older article’s broad treatment claims.
Give urinary changes their own attention
Difficulty passing urine, a weak stream or a feeling that your bladder has not emptied deserves a medical discussion. If you suddenly cannot pass urine, seek emergency care. Healthdirect — Urinary retention.
Write down what has changed, when it began and any medicines or supplements you use. Ask your GP what assessment is appropriate before choosing a product for the symptoms.
What about safety?
Saw palmetto can cause unwanted effects, including digestive symptoms, dizziness or headache, and may be unsafe during pregnancy or breastfeeding. Discuss it with a doctor or pharmacist rather than relying on a natural label. NCCIH — Saw palmetto.
Useful questions include what the product is meant to do, what evidence applies and how it fits with your medical care. There is no supplement protocol in this guide.
