HelloPharmacist Scorecard of Saw Palmetto 320 mg by Foods Plus

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Sep 10, 2026

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains 2 active ingredients of saw palmetto—the botanical extract used traditionally for urinary and prostate health. The remaining ingredients are inert fillers and binders: dicalcium phosphate, microcrystalline cellulose, silica, stearic acid, croscarmellose sodium, magnesium stearate, and pharmaceutical glaze.

These help hold the tablet together and have no therapeutic role.

Does it work?

Moderate evidence
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

This product doesn't appear to be marketed for a specific use, so we graded Saw Palmetto's overall clinical evidence instead.

Moderate

Some clinical evidence supports Saw Palmetto for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Transurethral resection of the prostate (TURP) — rated "Possibly Effective" (Natural Medicines).

The evidence for saw palmetto is mixed. It's rated possibly effective for recovery after transurethral resection of the prostate (a surgical procedure for the prostate).

However, for benign prostatic hyperplasia (BPH)—enlarged prostate—the data suggests it's possibly ineffective. For other uses like hair loss, chronic bronchitis, and non-neurogenic lower urinary tract symptoms, we don't have enough reliable evidence yet to say whether it works.

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 overall, and side effects when they do occur tend to be mild and reversible. The most common ones reported in trials are abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and decreased libido.

Rarely, skin reactions (fixed drug eruptions with blisters) and heart rhythm changes have been reported, though these are uncommon. You should not take this product during pregnancy or while breastfeeding.

The safety data advises against both because of possible hormonal effects and insufficient safety information.

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 you start, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (like warfarin or aspirin), hormonal contraceptives, or estrogen therapy. Saw palmetto may increase bleeding risk with the first group and could reduce the effectiveness of the second and third.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

Saw Palmetto 320 mg may be worth considering if you're looking into prostate or urinary health support, but the evidence for benign prostatic hyperplasia itself is weak. If you take blood thinners, contraceptive pills, or estrogen therapy, you'll need to check with your doctor or pharmacist first—this supplement could interfere with how they work.

It's not for use in pregnancy or while nursing.

Saw Palmetto 320 mg by Foods Plus: Common Questions

Does Saw Palmetto 320 mg by Foods Plus 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 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 might interfere with how hormonal contraceptives work because of its antiestrogenic effects. Talk to your doctor or pharmacist before combining them to make sure your birth control remains effective.
What are the most common side effects?
The ones reported most often are mild: abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and decreased libido. These are usually infrequent and reversible, but if they bother you, stop and talk to your pharmacist.
Is it safe during pregnancy?
No. The safety data advises against use during pregnancy because of possible hormonal effects and lack of safety information. If you're pregnant or planning to be, skip this product.
Does it really help with prostate enlargement?
The evidence suggests it's not very effective for benign prostatic hyperplasia (enlarged prostate). It is rated possibly effective for recovery after prostate surgery, but for the condition itself, the data doesn't support it working well.
Can I take it if I'm on a blood thinner like warfarin?
Not without checking with your doctor first. Saw palmetto may prolong bleeding time and could increase your risk of bleeding when combined with blood thinners or drugs like aspirin. You'll need personalized medical advice on whether it's safe for you.
