Saw palmetto
Serenoa repens: what the plant is, how a berry extract differs from powder and how to read the fatty-acid percentage on the label.
This substance has no health claim authorised in the European Union. So we describe what it is and how it is taken, but do not say what it does in the body.
What it is
Saw palmetto (Serenoa repens) is a low-growing palm from the south-eastern United States. Its dark berries were gathered as food by the native peoples of Florida; supplements use an extract of these berries.
Saw palmetto has no authorised health claims in the European Union. So we do not write about the prostate or urination; we describe the plant and how to compare products. If urinary symptoms trouble you, see a doctor: a supplement does not replace an examination.
How to read the label
Good extracts state standardisation to 85–95 % fatty acids and sterols. Unstandardised berry powder is cheaper, but the dose is larger and the composition less predictable. Complexes often pair saw palmetto with zinc, selenium, lycopene, nettle and pumpkin seed.
How it is taken, and precautions
Take as the pack directs, with a meal. The product is meant for adult men; it is not for children or for pregnant or breastfeeding women. People on blood thinners or hormone treatments should ask a doctor first.
Frequently asked questions
What does "85–95 % fatty acids" mean?
It is the extract's standardisation: how much of it is the berries' fatty acids and sterols. It lets you compare products.
Powder or extract?
A standardised extract is more concentrated and predictable; berry powder is cheaper but the dose is larger.
Can it replace seeing a doctor?
No. With any urinary symptoms, see a doctor first.
