What is Saw Palmetto for?

Saw Palmetto is the name of a palm-like plant that grows in the southeast US. The berries are then extracted to use for medicinal purposes, as it has been found to be effective in lowering a male hormone called dihydrotestosterone (DHT). DHT is a male hormone commonly found in patients with benign prostatic hyperplasia (BPH) and male hair loss. Saw palmetto works by inhibiting an enzyme to lower the concentration of DHT in the body. It may be helpful to treat symptoms of benign prostatic hyperplasia, probably in combination with other drugs like Tamsulosin.

How to use it?

Saw palmetto is available as capsules. The recommended dosage is 160 mg twice daily or 320 mg once daily, taken at the same time of the day.

What are the side effects of Saw Palmetto?

Saw Palmetto is likely safe and only causes some mild side effects in rare cases, such as nausea, vomiting, diarrhea, constipation, headache, and dizziness. Also, it may cause lower abdominal pain, especially when taken on an empty stomach.

Who should not take Saw Palmetto?

People who are allergic to Saw Palmetto or any component of the formulation.
