HelloPharmacist Scorecard of Saw Palmetto 320 mg by Herbal Secrets

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: saw palmetto extract at 320 mg per softgel capsule. Saw palmetto comes from the berries of a small palm tree and has traditionally been used to support prostate and urinary health.

The softgel also includes inactive ingredients — gelatin, vegetable glycerin, and shell ingredients — that hold and deliver the extract.

Does it work?

Leans against
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: support prostate health and urinary flow.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Non-neurogenic lower urinary tract symptoms (LUTS), Prostatitis, urinary symptoms, bladder function.
  • The closest evidence on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Saw Palmetto is rated "Insufficient Reliable Evidence To Rate" for Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Prostatitis, Non-neurogenic lower urinary tract symptoms (LUTS).

The evidence for saw palmetto is mixed. It's rated possibly effective for one specific prostate procedure (transurethral resection of the prostate, or TURP), but possibly ineffective for benign prostatic hyperplasia (BPH) — the enlarged prostate condition it's most commonly marketed for.

For hair loss (androgenic alopecia), chronic bronchitis, and lower urinary tract symptoms, the data we hold shows insufficient evidence to rate whether it works.

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Saw palmetto is generally well tolerated, and most people who take it experience no problems. When side effects do occur, they're usually mild and go away on their own — the most common are abdominal pain, constipation, diarrhea, dizziness, headache, nausea, and decreased libido.

Rarely, heart-related effects have been reported. Avoid this product during pregnancy and while breastfeeding — the safety data advises against it because of potential hormonal effects and lack of reliable safety information.

Why this rating?

  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 174 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

Before you start, check your exact medications against these drug types: blood thinners and antiplatelet drugs (moderate risk of increased bleeding), estrogens (moderate risk of reduced effectiveness), and birth control pills (moderate risk of reduced effectiveness).

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Saw palmetto might help with one specific prostate procedure, but the evidence for common uses like BPH is weak. If you're interested in it for urinary or prostate symptoms, talk it over with your doctor or pharmacist first — especially if you take blood thinners, hormonal medications, or birth control, since saw palmetto can interfere with how these work.

Does Saw Palmetto 320 mg by Herbal Secrets interact with any medications?
Yes. Based on its ingredients, Saw Palmetto 320 mg has a known interaction with 174 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Saw Palmetto 320 mg contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
Can I take this if I'm on birth control?
Not without checking first. Saw palmetto may reduce how well birth control works because of its antiestrogenic effects. Talk with your doctor or pharmacist about whether this product is right for you if you rely on hormonal contraception.
Can I take this if I'm on a blood thinner like warfarin?
No — saw palmetto can prolong bleeding time and raise your risk of bleeding complications. Bring this product to your doctor or pharmacist before you take it if you're on any blood thinner or antiplatelet medication.
Is this safe to take while pregnant or breastfeeding?
No. The safety data advises against use during pregnancy because of possible hormonal effects and lack of safety data. It's also not recommended while breastfeeding. Talk with your doctor if you're pregnant or planning to breastfeed.
What are the most common side effects?
Saw palmetto is generally well tolerated, but mild, reversible side effects can include abdominal pain, constipation, diarrhea, dizziness, headache, nausea, and decreased libido. These are uncommon and usually go away on their own.
Does this actually work for an enlarged prostate?
The evidence is weak. Saw palmetto is rated possibly ineffective for benign prostatic hyperplasia (BPH), the most common reason people take it. It's possibly effective for one specific prostate procedure, but for typical BPH symptoms, the data doesn't support it well.
