HelloPharmacist Scorecard of Saw Palmetto 2,400 mg by Nature's Truth

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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “Saw Palmetto Proprietary Blend” is a proprietary blend — the label gives one combined amount (2,400 mg) without saying how much of each component you get.

Saw Palmetto 2,400 mg contains 2 active ingredients: saw palmetto whole berry extract and saw palmetto itself — both sources of the herb's active compounds. The product also includes inactive ingredients (rice powder, gelatin, magnesium stearate, and silica) that serve as fillers and capsule material.

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: Herbal supplement for men's prostate 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), urinary flow — and 1 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 Prostate cancer, Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Prostatitis, Non-neurogenic lower urinary tract symptoms (LUTS).

Saw palmetto shows possibly effective evidence for one condition: transurethral resection of the prostate (TURP). For benign prostatic hyperplasia (BPH) — the most common reason people take saw palmetto — the data rates it possibly ineffective.

For other uses like chronic bronchitis, male pattern baldness (androgenic alopecia), and non-neurogenic lower urinary tract symptoms, there isn't enough reliable evidence in our data to rate effectiveness either way.

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 in adults, with mild and infrequent side effects that are reversible. The most common ones are abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and decreased libido.

Rarely, people have reported skin reactions, worsened acne, or heart-related symptoms like high or low blood pressure, irregular heartbeat, or chest pain — contact your doctor if you experience any of these. The safety data advises against use during pregnancy because of possible effects on hormones and lack of safety data.

Do not breastfeed while taking saw palmetto due to insufficient safety information. Talk with your doctor or pharmacist about whether this product is right for you in these situations.

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 Saw Palmetto 2,400 mg, double-check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs (such as warfarin or aspirin) — saw palmetto may increase bleeding risk. Also flag it if you're on estrogens or contraceptive drugs, because saw palmetto might reduce how well they work.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Saw Palmetto 2,400 mg might appeal to you if you're exploring options for prostate or urinary health, though evidence for its main uses is limited. If you take blood thinners, estrogen, or birth control, check with your doctor or pharmacist before starting — saw palmetto can interfere with how these work.

It's not meant for pregnancy or breastfeeding. Have a conversation with your healthcare provider about whether it fits your situation.

Saw Palmetto 2,400 mg by Nature's Truth: Common Questions

Does Saw Palmetto 2,400 mg by Nature's Truth interact with any medications?
Yes. Based on its ingredients, Saw Palmetto 2,400 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 2,400 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 might reduce how well contraceptive drugs work because of its antiestrogenic effects. Talk to your doctor or pharmacist before adding this product to your routine.
What are the most common side effects?
Mild ones: abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and decreased libido. Most adverse effects are infrequent and reversible. Rarely, people report skin reactions or heart symptoms — contact your doctor if that happens.
Is it safe during pregnancy or breastfeeding?
No. The safety data advises against saw palmetto in pregnancy because of possible hormone effects and lack of safety data, and against breastfeeding due to insufficient safety information. Talk with your doctor about this before using it.
Does saw palmetto actually work for benign prostatic hyperplasia (BPH)?
The evidence rates it possibly ineffective for BPH — the reason most people buy it. There's possibly effective evidence for one narrower condition (transurethral resection of the prostate, or TURP), but limited data on other urinary symptoms.
Can I take this with blood thinners like warfarin or aspirin?
Not without checking with your doctor or pharmacist first. Saw palmetto is reported to prolong bleeding time, which could increase your risk of bleeding when combined with blood thinners or antiplatelet drugs.
