HelloPharmacist Scorecard of Tribulus by Herbal Hills

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.

Herbal Hills Tribulus contains one active ingredient: a blend of Gokshur fruit extract and Gokshur fruit powder—both forms of the same plant source (tribulus). The capsules also contain silicon dioxide and an HPMC capsule shell as inactive ingredients to hold and deliver the powder.

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 Tribulus's overall clinical evidence instead.

Moderate

Some clinical evidence supports Tribulus 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 ingredient's overall clinical evidence instead.
  • On file: Sexual dysfunction — rated "Possibly Effective" (Natural Medicines).

Tribulus is possibly effective for sexual dysfunction based on the evidence we have on file. The research on athletic performance, though, suggests it's possibly ineffective for that use.

For benign prostatic hyperplasia (BPH, or enlarged prostate), the evidence is too thin to rate it either way—we simply don't have enough reliable data.

The evidence, ingredient by ingredient Tribulus

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.

Short-term use in healthy adults is generally well tolerated, but quality and long-term safety data are limited. The most common side effects are mild stomach complaints—abdominal pain, cramping, nausea, vomiting, diarrhea, or constipation—though in one study these occurred at about the same rate as placebo.

Rare serious adverse effects including liver or kidney injury, seizures, and chronic painful erection have been reported. Avoid tribulus during pregnancy because it may affect hormones and safety hasn't been established.

Also avoid it while breastfeeding due to lack of reliable safety information.

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 — Tribulus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 259 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 own doctor or pharmacist before taking this if you're on blood pressure-lowering drugs, diabetes medications, or lithium. Tribulus can lower blood pressure and blood sugar and may increase lithium levels—all Moderate-severity interactions that could require dose adjustments or closer monitoring.

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.

Tribulus may be worth considering if you're exploring options for sexual dysfunction, though the evidence is modest. Skip it if you take blood pressure medication, diabetes drugs, or lithium without checking first—the interactions are real and could affect how those drugs work.

Talk it over with your own doctor or pharmacist before you start, especially if you're on any regular medications or have liver or kidney concerns.

Tribulus by Herbal Hills: Common Questions

Does Tribulus by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Tribulus has a known interaction with 259 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Tribulus 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 pregnant or breastfeeding?
No. Tribulus is rated possibly unsafe in pregnancy because it may affect hormones and safety hasn't been established. Avoid it while breastfeeding too—there isn't enough reliable safety data. Talk to your doctor or pharmacist if you're planning pregnancy or are currently nursing.
What side effects should I expect?
Most people tolerate it well short-term. The most common complaints are mild stomach issues—cramping, nausea, diarrhea, or constipation—but in studies these happened about as often with placebo. Rare serious side effects like liver or kidney injury and seizures have been reported, so if you experience unusual symptoms, stop and check with your doctor.
Does tribulus actually work for sexual function?
The evidence suggests it's possibly effective for sexual dysfunction, meaning there's some supporting research but it's not ironclad. Results vary between people, and long-term safety data are limited.
Will this help my athletic performance?
No. The research we have indicates tribulus is possibly ineffective for improving athletic performance.
Why does quality vary so much in tribulus supplements?
Long-term safety and quality data are limited for tribulus products overall. This means testing standards and potency can vary between brands and batches, which is why consistency isn't always guaranteed.
