HelloPharmacist Scorecard of Prostol by Nature's Way

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

Prostol contains 2 active ingredients: sabal extract (saw palmetto) and urtica extract (stinging nettle). Saw palmetto is used to help with urinary and prostate symptoms, and stinging nettle is traditionally used to support urinary and prostate health as well.

The softgel also contains several inactive ingredients — plant glycerides, gelatin, glycerin, soybean oil, and color additives (caramel, titanium dioxide, and carmine) — that serve as the capsule shell and filler.

Does it work?

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: Dual action prostate health support.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Non-neurogenic lower urinary tract symptoms (LUTS), Prostatitis, Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Urinary symptoms, Prostate function.
  • The closest evidence on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Stinging Nettle is rated "Insufficient Reliable Evidence To Rate" for Benign prostatic hyperplasia (BPH).
  • 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 these ingredients is mixed. Saw palmetto is possibly ineffective for benign prostatic hyperplasia (enlarged prostate) based on the data we hold, though it's rated possibly effective for TURP (transurethral resection of the prostate, a surgical procedure).

Stinging nettle is possibly effective for diabetes, but we don't have established evidence on file for its use in prostate or urinary symptoms. For other conditions like hay fever, anemia, or asthma, the evidence is either insufficient or not rated in our data.

The evidence, ingredient by ingredient Saw Palmetto Stinging Nettle

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.

Both ingredients are generally well tolerated when used as directed. Saw palmetto's most common side effects are mild and reversible — abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and decreased libido have been reported.

Rare cases of heart rhythm problems have also been documented. Stinging nettle commonly causes constipation or diarrhea, and case reports describe rare liver injury and severe tongue swelling when the raw plant was used improperly.

Both ingredients are rated Likely Unsafe in pregnancy due to hormonal effects and insufficient safety data. Saw palmetto should be avoided while breastfeeding.

Stinging nettle's safety during breastfeeding has not been established, so talk with your doctor or pharmacist before using it if you're nursing.

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?
  • 2 of the 2 matched ingredients can interact with medications — Stinging Nettle, Saw Palmetto.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications; lithium.
  • For scale: 336 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 Prostol, check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs like warfarin or aspirin (Moderate risk of increased bleeding). Also double-check if you're on hormonal contraceptives or estrogen therapy (Moderate risk of reduced effectiveness), diabetes medications (Moderate additive effect on blood sugar), lithium (Moderate risk of lithium buildup), diuretics, or warfarin specifically.

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.

Prostol is meant to support prostate and urinary health, but the evidence for that purpose is not strong in our data. If you take any blood thinners, hormonal contraceptives, estrogens, diabetes medications, lithium, diuretics, or warfarin, you'll need to check this product with your own doctor or pharmacist before starting — the interactions could affect how those drugs work.

Do not take this product if you're pregnant or breastfeeding.

Prostol by Nature's Way: Common Questions

Does Prostol by Nature's Way interact with any medications?
Yes. Based on its ingredients, Prostol has a known interaction with 336 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Prostol 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 this affect my birth control?
Saw palmetto in Prostol may reduce how well your contraceptive works because it can have antiestrogenic effects. Talk to your doctor or pharmacist before adding this to your routine if you're taking hormonal contraceptives.
Can I take this if I'm on a blood thinner?
Saw palmetto may increase your bleeding risk when combined with blood thinners or antiplatelet drugs. Do not start Prostol without checking with your doctor or pharmacist first if you take warfarin, aspirin, or similar medications.
Is it safe in pregnancy?
No. Both saw palmetto and stinging nettle are rated Likely Unsafe in pregnancy because of possible hormonal effects and lack of safety data. Avoid this product if you're pregnant or trying to become pregnant.
What are the most common side effects?
Saw palmetto may cause abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and decreased libido. Stinging nettle typically causes constipation or diarrhea. Side effects are usually mild and reversible.
Does this actually work for prostate problems?
Saw palmetto is rated possibly ineffective for benign prostatic hyperplasia in our data. We don't have established evidence for stinging nettle's use in prostate symptoms either, so the evidence for this product's intended use is limited.
Can I take this with diabetes medication?
Stinging nettle may lower blood sugar and add to the effect of your diabetes medication, raising your risk of low blood sugar. Check with your doctor or pharmacist before taking Prostol if you're on diabetes drugs.
