HelloPharmacist Scorecard of Saw Palmetto Extract 160 mg by Nature's Blend

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 softgel delivers 2 active ingredients: saw palmetto berry extract (160 mg) and pumpkin seed oil. Saw palmetto has a long history in herbal medicine for prostate and urinary health, while pumpkin seed oil is also used to support urinary and prostate function.

The capsule itself is made from gelatin, olive oil, and glycerin — all inert ingredients that help deliver the actives.

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 its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients 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 ingredients' overall clinical evidence instead.
  • On file: Benign prostatic hyperplasia (BPH) — rated "Possibly Effective" (Pumpkin) (Natural Medicines).
  • On file: Transurethral resection of the prostate (TURP) — rated "Possibly Effective" (Saw Palmetto) (Natural Medicines).

For saw palmetto, the evidence is mixed. It's rated possibly effective for one specific urinary procedure (TURP), but possibly ineffective for benign prostate enlargement (BPH), which is one of the most common reasons people take it.

For hair loss, chronic bronchitis, and lower urinary tract symptoms, the evidence isn't established in the data we hold. Pumpkin seed oil is rated possibly effective for BPH, but the evidence for hair loss, cystitis, parasites, and urinary tract infections is insufficient.

In short, if prostate or bladder symptoms are your reason, the evidence is weak to mixed.

The evidence, ingredient by ingredient Saw Palmetto Pumpkin

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Orally, saw palmetto is generally well tolerated, though mild side effects — abdominal pain, constipation, diarrhea, nausea, headache, and dizziness — do occur. Very rarely, it's been linked to heart rhythm changes and a skin reaction.

Pumpkin seed oil is also generally well tolerated, with occasional mild stomach upset, nausea, or diarrhea; anaphylaxis (a severe allergic reaction) is extremely rare. Safety data advises against this product during pregnancy and while breastfeeding because saw palmetto's hormone-like activity raises concerns, and there isn't enough data on pumpkin seed oil supplements to know it's safe for your baby.

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

Why this rating?
  • 2 of the 2 matched ingredients can interact with medications — Pumpkin, Saw Palmetto.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 175 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.

Check with your doctor or pharmacist before taking this product if you use any of the following: hormonal birth control or estrogen therapy (saw palmetto may weaken their effect), blood thinners or antiplatelet drugs like warfarin or aspirin (risk of increased bleeding), or lithium (your lithium level might climb).

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 Extract 160 mg is best suited for adults over 18 who want to try herbal support for prostate or urinary symptoms — but know the evidence for it is modest. Be careful if you take birth control, hormone replacement therapy, blood thinners, or lithium; those warrant a check with your doctor or pharmacist before you start.

Pregnant women and those breastfeeding should avoid it. Talk with your own doctor or pharmacist about whether this product makes sense for your situation.

Saw Palmetto Extract 160 mg by Nature's Blend: Common Questions

Does Saw Palmetto Extract 160 mg by Nature's Blend interact with any medications?
Yes. Based on its ingredients, Saw Palmetto Extract 160 mg has a known interaction with 175 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Saw Palmetto Extract 160 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.
Will saw palmetto help my enlarged prostate?
The evidence is weak. Saw palmetto is rated possibly ineffective for benign prostate enlargement, even though many people take it for that reason. Your doctor can help you weigh whether to try it or explore other options.
Can I take this if I'm on birth control?
Not without talking to your doctor first. Saw palmetto may interfere with how well your birth control works because it can have antiestrogenic effects. This is a Moderate-severity interaction that requires a personalized decision with your healthcare provider.
What are the most common side effects?
Saw palmetto most often causes mild, reversible effects like abdominal pain, constipation, diarrhea, nausea, headache, and dizziness. Pumpkin seed oil occasionally causes mild stomach upset or nausea. Serious side effects are rare.
Is this safe to take while breastfeeding?
No. Saw palmetto safety data advises against use while breastfeeding, and there isn't enough information on pumpkin seed oil supplements in nursing mothers. Talk with your doctor or pharmacist about what's safe for you and your baby.
What's the difference between saw palmetto and pumpkin seed oil?
Both are used for prostate and urinary health, but they're separate plants. Saw palmetto comes from a berry; pumpkin seed oil comes from pumpkin seeds. This product combines both, so you get both sets of interactions and both potential benefits — though the evidence for either is modest.
Can I take this with my blood thinner?
Not without checking with your doctor. Saw palmetto may increase bleeding risk when combined with anticoagulants or antiplatelet drugs like warfarin or aspirin. Your doctor needs to know you want to add this before you start.
