Saw palmetto — the plant in men’s formulas
Serenoa repens
Serenoa repens is a dwarf palm that grows in the southeastern United States. Supplements use the fatty extract of its fruit.
Why people take it
Saw palmetto is the best-known plant in the men’s health category — it appears in almost every formula. That is a historically formed standard.
Clarity matters here: saw palmetto carries no established health wording under European regulation. It sits in the logic of traditional use, unlike zinc and selenium.
With saw palmetto the type of extract is critical. The lipidosterolic extract standardised to 85–95% fatty acids is exactly the form used in research; ordinary powdered berry is not the same thing. It is worth looking for the standardisation percentage on the label, not only the milligrams. This is a component taken as a course — assessment usually comes after several weeks, not in the first days.

Food sources
Serenoa repens is not a food plant — it is found only as a supplement or a herbal preparation.
Who should be careful
Saw palmetto may interact with hormone therapy and some prostate medicines — its use must be agreed with a doctor. It may also affect PSA test results: tell your doctor you are taking it before the test. It is not for women, pregnant women or people under 18.
Frequently asked questions
Why is it in almost every men’s formula?
It is a historically formed standard in the category. Its recognition is high, although it carries no established health wording.
Can it affect a PSA test?
Yes, that possibility is described. Be sure to tell your doctor that you take saw palmetto before the test.
Does saw palmetto affect a PSA test?
This is an important practical question: always tell your doctor you are taking the supplement before the test, so the result is interpreted in the right context. A supplement does not replace a urological examination.
How long does a usual course last?
Saw palmetto extract is normally taken as a course of several months, because assessing the effect over a short period loses its meaning. Before starting and during the course, follow-up with a urologist remains the main reference point, especially after the age of 50.
