Saw Palmetto Benefits, Dosage & Side Effects Supplement Information and Usage Guide

Saw Palmetto is commonly used to support prostate health and reduce urinary symptoms in men.

Saw Palmetto (Serenoa repens) is a small palm native to the southeastern United States, traditionally used for supporting prostate health in men. Its berries have long been used in Native American medicine.

Saw palmetto extracts are rich in fatty acids and phytosterols, which may help balance hormones and reduce symptoms of benign prostatic hyperplasia (BPH). It is typically consumed in capsule or softgel form.

Men often take saw palmetto for urinary comfort and prostate support. While some studies show benefits, especially for mild BPH symptoms, results are mixed and more standardized research is needed.

Side Effects

Saw Palmetto can support prostate health, but some users report mild effects as their hormone balance adjusts. Watch for:

  • Mild gastrointestinal upset—nausea, constipation, or diarrhea
  • Possible headache or dizziness in sensitive individuals
  • Rare changes in libido or sexual function, such as decreased libido or difficulty achieving erection
  • Occasional mild breast tenderness or changes in hormonal markers
  • Skin rash or itching in those allergic to palm species

Interactions

Possible interactions include:

  • 5α-reductase inhibitors and hormone therapies: Saw Palmetto’s antiandrogenic action may enhance effects of finasteride or Progesterone, potentially altering hormone balance.
  • Anticoagulant and antiplatelet agents: Mild antiplatelet properties of Saw Palmetto can add to warfarin or supplements like Garlic, increasing bleeding risk.
  • Diuretic medications: Saw Palmetto’s mild diuretic effect may augment drugs such as furosemide or supplements like Dandelion Root, affecting fluid balance.
  • CYP3A4 substrates: Saw Palmetto can inhibit CYP3A4, potentially raising levels of medications like statins or CoQ10; monitor for toxicity.

Precautions

Before incorporating Saw Palmetto, verify you’re not in any of these cautionary categories. If you are, consult your healthcare provider:

  • Pregnant or breastfeeding women: Not recommended—may affect hormone balance; avoid completely
  • Individuals with hormone-sensitive cancers: May alter hormone levels; avoid if you have prostate or breast cancer history
  • People on hormonal therapies (e.g., testosterone, estrogen): Potential to interfere; use only under medical guidance
  • Those taking blood-thinning medications: Saw Palmetto may increase bleeding risk; monitor clotting closely
  • Patients scheduled for surgery: Possible hormone and bleeding interactions; discontinue at least two weeks prior

Studies

These studies provide scientific insights into Saw Palmetto benefits:

A 2012 Cochrane review concluded that 320 mg/day of saw palmetto extract provides no significant benefit over placebo for lower urinary tract symptoms due to benign prostatic hyperplasia (BPH).

A 1999 randomized, double-blind trial of 160 mg twice daily found saw palmetto modestly improved peak urinary flow rate by 9% versus 3% with placebo (P < 0.05) in men with BPH.

A 2009 comparative RCT showed that over 12 months, saw palmetto and tamsulosin achieved similar symptom-score reductions, but tamsulosin led to greater urinary flow improvements (P < 0.05).

A 2013 double-blind study reported no significant changes in prostate volume or PSA levels after 6 months of 320 mg/day saw palmetto versus placebo.
