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.

From our pharmacy team — supplement deep dive

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 11, 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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Gokshur fruit extract and powder blend (tribulus). The capsule itself is made from HPMC (a plant-based capsule material) and contains silicon dioxide as an inactive ingredient.

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. The evidence for athletic performance is possibly ineffective—meaning it likely doesn't help.

For benign prostatic hyperplasia (enlarged prostate), we don't have enough reliable evidence to rate whether it works.

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.

Tribulus is generally well tolerated in the short term for healthy adults, but we don't have much long-term safety data or information about product quality across brands. Avoid it during pregnancy because it may affect hormones and safety hasn't been established.

Don't use it while breastfeeding due to a lack of reliable safety information. Side effects are usually mild—abdominal pain, cramping, nausea, vomiting, diarrhea, and constipation are the most common complaints, though in one study these rates were similar to placebo.

Rare serious effects including liver and kidney injury, seizures, and persistent painful erection have been reported. A case of acute kidney injury and hepatitis occurred in someone who drank 2 liters of tribulus water daily for two days.

Side effects, ingredient by ingredient Tribulus

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 your exact medications in the tool below if you take blood pressure drugs, diabetes medication, or lithium. Tribulus can lower blood pressure and blood sugar and may raise lithium levels, all at a Moderate severity.

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 help with sexual dysfunction, though the evidence is modest. If you take blood pressure pills, diabetes medication, or lithium, check with your pharmacist before starting—dose adjustments might be needed.

Avoid it in pregnancy and while breastfeeding. Talk to your pharmacist or doctor about whether it's right for you.

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?

What is Gokshur fruit extract?
Gokshur is another name for tribulus, a plant whose fruit and extract are used in this supplement.
Does tribulus really help with sexual dysfunction?
