HelloPharmacist Scorecard of Pro-Male by Douglas Laboratories

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Pro-Male is a single-ingredient product containing saw palmetto extract in capsule form. Saw palmetto is a botanical supplement derived from the fruit of the saw palmetto plant, traditionally used in men's health formulations.

The capsule also contains cellulose, gelatin, and vegetable stearate as inactive ingredients (binders 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: prostate health and urinary function.
  • 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), prostate support, male urinary health.
  • 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 Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS), Prostatitis, Non-neurogenic lower urinary tract symptoms (LUTS).

The data we hold on saw palmetto shows mixed results. It's rated possibly effective for one specific urinary procedure (TURP — transurethral resection of the prostate), but possibly ineffective for benign prostatic hyperplasia (BPH), which is a common reason men take saw palmetto.

For other uses like hair loss or chronic bronchitis, we don't have enough reliable evidence to rate how well 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, and side effects that do occur tend to be mild and reversible. The most common ones include abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and vomiting.

Rarely, cases of heart rhythm changes and high or low blood pressure have been reported. There's also one documented case of a skin reaction (fixed drug eruption) that cleared when the supplement was stopped.

Saw palmetto is not safe during pregnancy or while breastfeeding. The safety data advises against use in both situations because of possible effects on hormones and insufficient safety information.

If you're pregnant, planning to become pregnant, or nursing, talk with your doctor or pharmacist before taking this product.

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 Pro-Male, check your medications against these drug types: blood thinners and antiplatelet drugs (anticoagulants and antiplatelets) — saw palmetto may increase bleeding risk; estrogens and birth control pills (contraceptive drugs) — saw palmetto might make them less effective. Use the search tool on this page to look up your specific prescriptions.

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.

Pro-Male is a straightforward saw palmetto supplement that may appeal to men interested in prostate health, though the evidence for its effectiveness in benign prostatic hyperplasia is limited. If you take blood thinners, birth control, or estrogens, you'll need to check with your doctor or pharmacist first — saw palmetto may interfere with how these work.

It's not appropriate during pregnancy or breastfeeding.

Pro-Male by Douglas Laboratories: Common Questions

Does Pro-Male by Douglas Laboratories interact with any medications?
Yes. Based on its ingredients, Pro-Male 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?
Pro-Male 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 this reduce how well my birth control works?
Saw palmetto might interfere with how contraceptive drugs work, according to the data we have. Talk with your doctor or pharmacist before taking this product if you're on birth control — they can help you decide whether it's right for you or suggest monitoring.
What are the most common side effects?
The most frequent side effects are mild and include abdominal pain, constipation, diarrhea, dizziness, fatigue, headache, nausea, and vomiting. Most people tolerate it well, and any side effects are usually reversible if you stop taking it.
Can I take this while pregnant or breastfeeding?
No. Saw palmetto is rated not safe during pregnancy because of possible effects on hormones and lack of safety data, and it's also not recommended while breastfeeding due to insufficient safety information. Talk with your doctor or pharmacist about alternatives if you're pregnant, planning to become pregnant, or nursing.
Does this actually work for prostate problems?
The evidence is mixed. Saw palmetto is rated possibly ineffective for benign prostatic hyperplasia (BPH), which is the most common reason men use it. It is rated possibly effective for one specific prostate procedure (TURP), but for most prostate and urinary symptoms we don't have strong evidence.
I'm on a blood thinner — is this safe?
Saw palmetto may prolong bleeding time and increase your bleeding risk if you're taking anticoagulants or antiplatelet drugs. Talk with your doctor or pharmacist before starting this product if you're on any blood thinner or anti-clotting medication.
Are there any fillers or other ingredients I should know about?
This product contains only saw palmetto as the active ingredient. The inactive ingredients are cellulose, gelatin, and vegetable stearate — these are standard capsule materials and binders.
