HelloPharmacist Scorecard of Tribulus Extract by Herbadiet

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.

This product contains one active ingredient: tribulus terrestris fruit extract. The capsule itself is made from vegetable cellulose, an inert shell material.

Tribulus has been used traditionally to support sexual function and athletic performance, though the strength of evidence varies. The extract is derived from the fruit of the Tribulus terrestris plant.

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: enhance libido and promote testosterone levels.
  • We looked for evidence on: Erectile dysfunction (ED), Male infertility, Premature ejaculation, Sexual dysfunction, Hypogonadism, Low testosterone — and 2 related terms.
  • The strongest evidence on file: Tribulus is rated "Possibly Effective" for Sexual dysfunction (Natural Medicines).
  • Also on file: Tribulus is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED), Premature ejaculation, Male infertility.

For sexual dysfunction, tribulus is rated possibly effective — meaning there is some evidence it may help, but more research is needed to be certain. For athletic performance, the evidence points to possibly ineffective.

For benign prostatic hyperplasia (enlarged prostate), we don't have 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.

Short-term use in healthy adults appears generally well tolerated, though long-term safety data and product quality information are limited. The safety data advises against use during pregnancy because tribulus may affect hormones and safety has not been established.

It should also be avoided while breastfeeding due to lack of reliable safety information. Rare serious side effects have been reported, including liver and kidney injury, seizures, and chronic painful erection.

More common but usually mild effects are abdominal pain, cramping, nausea, vomiting, diarrhea, and constipation — though in one study these complaints occurred at similar rates in both tribulus and placebo groups. One case report documented severe effects (weakness, seizures, liver inflammation, acute kidney injury) after consuming very high doses of tribulus water over a short period.

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 taking this product, check with your doctor or pharmacist if you take blood pressure-lowering drugs, diabetes medications, or lithium. Tribulus may lower your blood pressure or blood sugar and could raise lithium levels, all rated Moderate severity — meaning dose adjustments or closer monitoring may be needed.

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.

Tribulus may be worth considering if you're interested in possibly supporting sexual function, though the evidence is modest. If you take blood pressure medications, diabetes medications, or lithium, this product requires careful review with your doctor or pharmacist before starting — it could affect how those drugs work.

Talk with your healthcare provider about whether it's right for you, especially if you're pregnant, breastfeeding, or have liver or kidney concerns.

Tribulus Extract by Herbadiet: Common Questions

Does Tribulus Extract by Herbadiet interact with any medications?
Yes. Based on its ingredients, Tribulus Extract 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 Extract 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 — the safety data advises against it. Tribulus may affect hormones during pregnancy and safety hasn't been established, so it's rated possibly unsafe. There's also not enough reliable information to know if it's safe while breastfeeding. Talk with your doctor or pharmacist before considering it in either situation.
Does tribulus really work for sexual dysfunction?
The evidence suggests it may help, but we'd call it possibly effective — meaning there's some research backing it, but we need more studies to be sure. Results vary from person to person.
What are the most common side effects?
Mild gastrointestinal effects like abdominal pain, cramping, nausea, vomiting, diarrhea, or constipation can occur. In one study, though, these happened at about the same rate in people taking tribulus and those on placebo.
Is this product safe to use long-term?
Short-term use in healthy adults appears generally well tolerated. However, long-term safety data are limited, and quality information on products varies. If you're thinking about using it regularly, talk it over with your doctor or pharmacist first.
What exactly is tribulus terrestris?
It's an extract from the fruit of the Tribulus terrestris plant, a vine traditionally used in herbal medicine. This product contains that single extract as its active ingredient.
