HelloPharmacist Scorecard of Saw Palmetto Complex by Wonder 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.

From our pharmacy team — supplement deep dive

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Saw Palmetto Complex contains three active ingredients. Pumpkin seed oil is included for benign prostatic hyperplasia (enlarged prostate).

Saw palmetto extract is traditionally used for prostate and urinary symptoms. Uva ursi extract is meant to support urinary tract health.

The product also contains inactive ingredients—gelatin, vegetable glycerin, natural caramel color, silica, and soy lecithin—that serve as the capsule and binders.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: prostate and urinary health for men.
  • We looked for evidence on: Benign prostatic hyperplasia (BPH), Non-neurogenic lower urinary tract symptoms (LUTS), Overactive bladder, Urinary tract infections (UTIs), Prostatitis, Chronic prostatitis and chronic pelvic pain syndrome (CP/CPPS) — and 2 related terms.
  • The strongest evidence on file: Pumpkin is rated "Possibly Effective" for Benign prostatic hyperplasia (BPH) (Natural Medicines).
  • Also on file: Uva Ursi is rated "Possibly Ineffective" for Urinary tract infections (UTIs).
  • Also on file: Saw Palmetto is rated "Possibly Ineffective" for Benign prostatic hyperplasia (BPH).

The evidence for these ingredients is mixed. Pumpkin seed oil is possibly effective for benign prostatic hyperplasia, but evidence is insufficient for hair loss, bladder pain (interstitial cystitis), parasites, and urinary tract infections.

Saw palmetto is possibly effective for a specific prostate procedure (transurethral resection of the prostate) but possibly ineffective for benign prostatic hyperplasia itself; evidence is also insufficient for cough, hair loss, and lower urinary tract symptoms. Uva ursi is possibly ineffective for urinary tract infections, and evidence is insufficient for cough and prostate enlargement.

In short, the evidence supporting these ingredients for their traditional uses is limited or mixed.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Pumpkin seed oil and saw palmetto are generally well tolerated in most adults, though mild side effects like stomach discomfort, diarrhea, nausea, and headache can occur. Saw palmetto rarely causes skin reactions or changes in desire.

Uva ursi is well tolerated at low doses for short-term use only; high doses (20 grams or more of dried herb) can cause serious toxicity including convulsions and delirium, and very high doses may be fatal. Avoid uva ursi for prolonged use.

Saw palmetto is not safe during pregnancy or breastfeeding. Pumpkin as food is fine in pregnancy and lactation, but safety of concentrated seed supplements is not well studied—talk with your doctor.

Uva ursi should be avoided during pregnancy (may stimulate the uterus) and breastfeeding (insufficient safety data).

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?
  • 3 of the 3 matched ingredients can interact with medications — Uva Ursi, Pumpkin, Saw Palmetto.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; lithium.
  • For scale: 888 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 take this, double-check blood thinners or antiplatelet drugs (Moderate risk—saw palmetto may increase bleeding), estrogens and birth control pills (Moderate—saw palmetto may reduce their effectiveness), and lithium (Moderatepumpkin seed oil and uva ursi may raise its level). Also check if you take drugs metabolized by your liver via CYP2C19 or CYP3A4 pathways, glucuronidated drugs, or urinary acidifying agents (Moderate for uva ursi, though these effects are theoretical in humans).

Use the medication checker on this page to be sure.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product combines three herbs traditionally linked to prostate and urinary health, but the evidence is weak. It's a reasonable option to discuss with your doctor if you're exploring natural support for these areas—but only if none of your medications are on the interaction list, especially blood thinners, birth control, estrogens, or lithium.

Uva Ursi extract6 drug types · 803 drugs

Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP2C19 substrates.
In vitro, uva ursi appears to inhibit cytochrome CYP2C19. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, uva ursi may decrease the metabolism of CYP3A4 substrates.
In vitro, uva ursi appears to inhibit CYP3A4. This effect has not been reported in humans.

Likelihood Possible Evidence D
Glucuronidated Drugs

Theoretically, uva ursi may increase levels of drugs metabolized by glucuronidation.
In vitro, uva ursi extract appears to strongly inhibit UDP-glucuronosyltransferase (UGT) 1A1 (UGT1A1). However, uva ursi extract does not appear to inhibit UGT1A1 in animal models. This effect has not been reported in humans.

Likelihood Possible Evidence D
Lithium

Theoretically, uva ursi may increase lithium levels, necessitating a decrease in dose.
Uva ursi may have diuretic properties. Diuretics may increase lithium reabsorption with sodium in the proximal tubule of the kidney. Theoretically, uva ursi might reduce excretion and increase levels of lithium.

Likelihood Probable Evidence D
Urinary Acidifying Agents

Effects of uva ursi in the urinary tract may be reduced by urinary acidifying agents.
Uva ursi seems to work best in alkaline urine. Theoretically, taking uva ursi with medications known to acidify the urine may decrease any effects of uva ursi on the urinary tract.

Likelihood Possible Evidence D
P-Glycoprotein Substrates

Theoretically, uva ursi may alter the levels of drugs transported by P-glycoprotein.
In vitro, uva ursi appears to inhibit the multi-drug transporter protein, P-glycoprotein. This effect has not been reported in humans.

Saw Palmetto Complex by Wonder Laboratories: Common Questions

Does Saw Palmetto Complex by Wonder Laboratories interact with any medications?
Yes. Based on its ingredients, Saw Palmetto Complex has a known interaction with 887 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Saw Palmetto Complex contains 3 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.
Is it safe to use this while taking birth control?
No—saw palmetto in this product may reduce how well your birth control works by interfering with estrogen. Talk to your pharmacist or doctor before taking it if you're using contraceptives.
What are the most common side effects?
Stomach upset, nausea, diarrhea, and abdominal discomfort are the most frequently reported. Saw palmetto may also cause headache, fatigue, or dizziness in some people.
Can I take this while pregnant or breastfeeding?
No. Saw palmetto and uva ursi should be avoided in pregnancy and while breastfeeding due to lack of safety data and potential hormone effects. Pumpkin as food is fine, but concentrated supplements haven't been well studied in these situations—talk to your doctor.
Does this actually work for prostate problems?
The evidence is mixed. Pumpkin seed oil is possibly effective for benign prostatic hyperplasia. Saw palmetto is possibly ineffective for it, though it may help with a specific prostate procedure. Uva ursi evidence for prostate issues is insufficient. These aren't proven solutions.
Can I take this long-term?
Uva ursi should only be used short-term; long-term or high-dose use can cause serious toxicity. The other ingredients appear okay longer-term in most people, but check with your pharmacist about your individual situation.
What if I'm on lithium for bipolar disorder?
Don't take this product. Both pumpkin seed oil and uva ursi may reduce how your kidneys clear lithium, raising your level and risking toxicity. Your dose would likely need adjustment, so talk to your prescriber.
