Saw palmetto

Also known as: Serenoa repens, sabal

Saw palmetto is a palm whose berries are made into a lipid extract used for an enlarged prostate. However, large good-quality trials have not shown a clear benefit over placebo.

What it is used for

  • urinary symptoms with an enlarged prostate – weak evidence, large trials and reviews show no clear effect
  • androgenetic hair loss – weak evidence from small studies

Forms and how they differ

lipidosterolic extract (hexane / CO₂)

the most studied form, standardised to fatty acids and sterols

berry powder

weaker, lower active content

combinations with pumpkin, zinc, pygeum

typical prostate blends – quality depends on the label

When to take it

With food, for better absorption and fewer stomach complaints.

Pairs well with

Pumpkin seed, beta-sitosterol, zinc.

Do not combine / separate

Do not combine with hormone therapy or prostate medicines without asking your doctor.

Watch out for

Not suitable during pregnancy or breastfeeding. Be careful with blood thinners, hormone therapy and before surgery. With urinary problems always see a doctor first – other causes must be ruled out.

Safety

Generally well tolerated; occasionally causes stomach upset or headache. Do not exceed the label dose.

Practical tip

A supplement does not replace preventive urological check-ups, including PSA.
