Quick Answers

What is saw palmetto used for?

Saw palmetto is used in herbal medicine to help relieve urinary symptoms associated with mild to moderate benign prostatic hyperplasia, or BPH.

What is BPH?

BPH is a non-cancerous enlargement of the prostate. It can make urination slower, more frequent, or feel incomplete.

Why does saw palmetto matter for prostate health?

For men dealing with symptoms such as weak urine flow, frequent urination, or getting up often at night, saw palmetto may help reduce those urinary symptoms.

Is saw palmetto for hair loss?

Jamieson does not position its Saw Palmetto product for hair loss. Its approved use is prostate and urinary-symptom support.

What is saw palmetto?

Saw palmetto, or Serenoa repens, is a small palm whose fruit is used in herbal supplements. 

It’s most commonly used for men’s prostate health, especially when an enlarged prostate is causing urinary symptoms such as a weak stream, frequent urination, or feeling like the bladder hasn’t fully emptied. 

How does saw palmetto support the body?

As the prostate enlarges, it can press against the urethra, the tube that carries urine out of the body. That can make it harder to start or maintain urine flow and can increase the need to urinate, including at night. 

Saw palmetto is used to help relieve these lower urinary tract symptoms associated with mild to moderate BPH, which is why it’s most relevant for men whose health goal is maintaining comfortable urinary function as they age. 

Which health goals can saw palmetto support?

Men’s Health

Saw palmetto supports prostate health and may help relieve urinary symptoms associated with mild to moderate BPH.

Healthy Aging

Prostate enlargement becomes more common with age, so saw palmetto may be relevant for men managing age-related urinary changes.

Urinary Comfort

Saw palmetto may help with symptoms such as weak urine flow, incomplete emptying, and frequent daytime or nighttime urination.

How can saw palmetto fit into your routine?

Saw palmetto is most relevant when prostate-related urinary symptoms are starting to affect everyday comfort or sleep. 

  • If your urine stream feels weaker: BPH can make it harder to maintain normal flow. 
  • If you’re going more often: Saw palmetto is used for frequent daytime and nighttime urination associated with BPH. 
  • If sleep is being interrupted: Reducing nighttime bathroom trips can matter for both urinary comfort and sleep quality. 
  • Don’t self-diagnose prostate symptoms: New or worsening urinary changes should be assessed by a healthcare practitioner to rule out other causes. 

*It is important to consult your trusted healthcare practitioner before adding any new natural health supplement to your routine. 

What should you look for in a saw palmetto supplement?

Start with the extract strength and whether the product is specifically licensed for prostate and urinary-symptom support.

  • Look for Serenoa repens fruit: This is the medicinal part recognized by Health Canada. 
  • Check the extract ratio: Jamieson uses an 8:1 extract, which tells you the fruit has been concentrated. 
  • Check the equivalent amount: Jamieson’s 125 mg extract is equivalent to 1,000 mg of saw palmetto fruit. 
  • Match the claim to your goal: If you’re choosing saw palmetto for prostate health, look for a product licensed for urinary symptoms associated with BPH. 
  • Consider convenience: Jamieson’s product is one softgel daily with a meal. 
  • Rule out other causes first: A healthcare practitioner should assess prostate symptoms before use, including to exclude prostate cancer. 
  • Look for an NPN: Jamieson Prostease Saw Palmetto is licensed under NPN 80018075. 

For more than 100 years, Jamieson has combined scientific expertise with rigorous quality testing. Every product is backed by the Jamieson 360 Quality Promise.
