HelloPharmacist Scorecard of Saw Palmetto 500 mg by Meijer

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.

From our pharmacy team — supplement deep dive

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 at 500 mg per capsule. Saw palmetto is an herbal extract from the berries of the saw palmetto plant, traditionally used for urinary and prostate health.

The capsule also contains inactive ingredients — gelatin, silica, and magnesium stearate — which help form and stabilize the supplement.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Saw Palmetto's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Men's health.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Non-neurogenic lower urinary tract symptoms (LUTS), Prostate cancer, Prostatitis, Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Androgenic alopecia — and 2 related terms.
  • 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 Androgenic alopecia, Prostate cancer, Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Prostatitis, and more.

For benign prostatic hyperplasia (BPH, or enlarged prostate), the evidence rates saw palmetto as possibly ineffective. For transurethral resection of the prostate (TURP), it's rated possibly effective, though the data is limited.

For other uses listed — chronic bronchitis, hair loss, and lower urinary tract symptoms — we don't have enough reliable evidence to rate whether it works. If you're considering this for a specific condition, talk it over with your doctor to see whether the evidence supports it for your situation.

The evidence, ingredient by ingredient Saw Palmetto

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 side effects tend to be mild and reversible. The most common ones reported in studies are abdominal pain, constipation, diarrhea, nausea, headache, dizziness, fatigue, decreased libido, vomiting, and rhinitis.

Rarely, skin reactions (including fixed drug eruptions with blisters) and heart rhythm issues have been reported; a few cases of severely low heart rate and heart block were documented, though these are uncommon. Do not use saw palmetto during pregnancy or while breastfeeding.

The safety data is insufficient, and the ingredient may affect hormones — the facts rate it as likely unsafe in pregnancy and lactation. If you're pregnant, trying to conceive, or nursing, talk with your doctor or pharmacist before considering this supplement.

Side effects, ingredient by ingredient Saw Palmetto

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Saw Palmetto.
  • 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 taking this product, double-check it with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (such as warfarin, aspirin, or clopidogrel) — saw palmetto may increase your risk of bleeding. Also flag it if you're taking estrogens or birth control pills, as saw palmetto may reduce their effectiveness.

Altogether, these interactions span 174 individual medications.

The bottom line

Scorecard at a glanceFully disclosed formula with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

Saw palmetto may be worth considering if you're exploring options for certain prostate-related conditions, but it comes with real medication interactions — especially with blood thinners and birth control. If you take any prescription medications, particularly anticoagulants, antiplatelet drugs, estrogens, or contraceptives, check with your doctor or pharmacist before starting this supplement.

It's not for use during pregnancy or breastfeeding.

Saw Palmetto 500 mg by Meijer: Common Questions

Does Saw Palmetto 500 mg by Meijer interact with any medications?
Yes. Based on its ingredients, Saw Palmetto 500 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 500 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.
Will saw palmetto affect my birth control?
Possibly. Saw palmetto may have antiestrogenic effects and could theoretically interfere with how well your contraceptive works. If you're on birth control, check with your doctor or pharmacist before adding this supplement to make sure it's safe for you.
Can I take this if I'm on a blood thinner like warfarin?
You need to check with your doctor or pharmacist first. Saw palmetto is reported to prolong bleeding time, so it may increase your risk of bleeding if combined with blood thinners or antiplatelet drugs like aspirin or clopidogrel.
Is saw palmetto safe during pregnancy?
No. Saw palmetto is rated as likely unsafe in pregnancy because of possible effects on hormones and a lack of safety data. If you're pregnant or planning to become pregnant, avoid this product and talk with your doctor about safer alternatives.
What side effects might I notice?
Most side effects are mild and infrequent. The ones reported most often are abdominal pain, constipation, diarrhea, nausea, headache, dizziness, fatigue, and decreased libido. Serious side effects (like skin reactions or heart rhythm problems) are rare but have been reported in individual cases.
Does saw palmetto actually work for an enlarged prostate?
The evidence is limited. For benign prostatic hyperplasia, it's rated as possibly ineffective. If you're dealing with prostate symptoms, talk with your doctor about what the science supports for your specific situation.
Can I breastfeed while taking this?
No. Saw palmetto is rated as likely unsafe while breastfeeding due to insufficient safety information. Avoid this product if you're nursing, and discuss your options with your doctor or pharmacist.
