About​

Saw Palmetto is a palm that grows in the southeastern United States. The berries are used to make the saw palmetto supplements. There is little science on the supplement and the science that does exist does not reliably point to any benefits.

Forms​

Can be found in capsule, softgel, tablet, ground, died, liquid extract, and powdered tea forms. Due to lack of science, there is no recommended form.

Benefits​

One study showed that taking 320mg of saw palmetto daily for two months before transurethral resection of the prostate can reduce time spent in surgery, time in hospital, blood loss, and risk of problems during surgery.

Few studies have been done on saw palmetto and none have found serious side effects.

Reported side effects include:

  • Dizziness
  • Headache
  • Nausea
  • Vomiting
  • Diarrhea
  • Constipation

Other Uses​
