HelloPharmacist Scorecard of Tribulus Terrestris 625 mg 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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 12, 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: Tribulus terrestris fruit extract, 625 mg per capsule. It also includes inactive ingredients — gelatin capsule material, cellulose, and magnesium stearate — that help hold the supplement together.

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. For athletic performance, the data suggests it's possibly ineffective.

For benign prostatic hyperplasia (enlarged prostate), we don't hold enough reliable evidence to rate it either way.

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 long-term safety data are limited and quality varies. Avoid it during pregnancy — the safety data advises against use because it may affect hormones and hasn't been established as safe.

Also avoid it while breastfeeding due to lack of reliable safety information. Side effects are usually mild — abdominal pain, cramping, nausea, vomiting, diarrhea, or constipation — though one study found these occurred at similar rates in people taking tribulus and those on placebo.

Rare serious effects reported include liver and kidney injury, seizures, and chronic painful erection. One case involved severe weakness, seizures, and kidney injury in someone drinking 2 liters of tribulus water daily for two days.

Side effects, ingredient by ingredient Tribulus

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.

Before you start, check any blood pressure drugs (antihypertensives) or diabetes medications you take — tribulus can lower both and increase the risk of dangerously low blood pressure or low blood sugar. Also flag lithium with your pharmacist, since tribulus might raise its levels.

All three are Moderate interactions.

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 and is worth a conversation if that's your goal. If you take blood pressure medication, diabetes medication, or lithium, check your exact drugs with our tool before starting — the interactions are Moderate and could affect how well those medications work.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, taking tribulus with antihypertensive drugs might increase the risk of hypotension.
Animal research shows that tribulus can lower blood pressure by inhibiting angiotensin-converting enzyme (ACE). Tribulus has also demonstrated hypotensive effects in pre-hypertensive adults.

Likelihood Possible Evidence D
Lithium

Theoretically, tribulus might increase the levels and clinical effects of lithium.
Tribulus is thought to have diuretic properties. Due to these potential diuretic effects, tribulus might reduce excretion and increase levels of lithium. The dose of lithium might need to be decreased.

Tribulus Terrestris 625 mg by Wonder Laboratories: Common Questions

Does Tribulus Terrestris 625 mg by Wonder Laboratories interact with any medications?
Yes. Based on its ingredients, Tribulus Terrestris 625 mg 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 Terrestris 625 mg 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.
Does tribulus actually work for sexual dysfunction?
The evidence suggests it's possibly effective — meaning there's some supporting research, but it's not a sure thing. Results vary from person to person, and you may need to try it for a reasonable period to know if it helps you.
Can I take this while pregnant or breastfeeding?
No. The safety data advise against tribulus during pregnancy because it may affect hormones and hasn't been proven safe. There's also not enough reliable safety information for breastfeeding, so avoid it then too. Talk to your OB or midwife if you're thinking about it.
What are the common side effects?
Mild stomach upset — cramping, nausea, vomiting, diarrhea, or constipation — is the main one you might see. In studies, these occurred at about the same rate as in people taking placebo, so they may not be directly from tribulus. Serious side effects are rare but have been reported.
Is this safe for long-term use?
The evidence for short-term safety in healthy adults is decent, but long-term safety data are thin. Quality can vary between brands too. If you're thinking of using it regularly, run it by your pharmacist first.
Will this help me build muscle or improve athletic performance?
The evidence suggests tribulus is possibly ineffective for athletic performance, so it's not a reliable choice if that's your goal. There are other options worth discussing with a trainer or pharmacist.
What's in this besides the active ingredient?
The capsule is made of gelatin, and it contains cellulose and magnesium stearate to keep everything stable. These are standard inactive ingredients used in supplements and medications.
