Saw palmetto (Serenoa repens)
What it is
One of the most popular prostate supplements in the world, but three Cochrane systematic reviews — including the most recent 2024 update — all concluded saw palmetto is no better than placebo for improving urinary flow or BPH symptoms. Despite strong marketing, it simply does not work. Consult your doctor about evidence-based options like alpha-blockers or 5-alpha reductase inhibitors.
Dose
320 mg/day standardised extract (85–95% fatty acids); consistent Cochrane evidence shows no benefit over placebo
Time of day & tips
Take with food to reduce stomach upset. No major drug interactions at standard doses. Given lack of clinical evidence, discuss with your doctor before continuing long-term use.
