HelloPharmacist Scorecard of Tribulus Maximus 250 by LifeLink

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.

Tribulus Maximus 250 is a single-ingredient product: each tablet or pill contains tribulus terrestris, a plant extract. The remaining ingredients—dicalcium phosphate, hydroxypropylcellulose, stearic acid, croscarmelose sodium, and magnesium stearate—are inactive binders, fillers, and flowing agents that help form and stabilize the tablet.

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: Safe non-hormonal treatment for infertility and reproductive disorders.
  • We looked for evidence on: Male infertility, Erectile dysfunction (ED), Premature ejaculation, Sexual dysfunction, Polycystic ovary syndrome (PCOS), Menopausal symptoms — and 3 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), Menopausal symptoms, Polycystic ovary syndrome (PCOS), Premature ejaculation, and more.

Tribulus terrestris is rated Possibly Effective for sexual dysfunction based on available clinical evidence. The data on athletic performance suggests it is Possibly Ineffective for that purpose.

For benign prostatic hyperplasia (BPH)—enlarged prostate—the evidence is too limited for us to rate it either way. If sexual health is your reason for considering this product, talk with your doctor about whether it's the right fit for you.

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 short-term in healthy adults, but quality and long-term safety data are limited. The most common side effects are gastrointestinal: abdominal pain, cramping, nausea, vomiting, diarrhea, or constipation—though in one study these complaints were similar between people taking tribulus and those on placebo.

Rare serious effects including liver or kidney injury and seizures have been reported. Do not use tribulus during pregnancy because it may affect hormones and safety is not established.

Avoid while breastfeeding due to insufficient safety data.

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 Tribulus Maximus 250, double-check your medications with a pharmacist or the tool on this page, especially if you take blood pressure drugs, diabetes medications, or lithium. These carry Moderate-severity interaction risks with tribulus.

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 help with sexual dysfunction, but it's not proven to boost athletic performance. If you take blood pressure medication, diabetes drugs, or lithium, check with your pharmacist first—tribulus can affect how these work.

Short-term use in otherwise healthy people tends to be tolerated well, but long-term safety isn't well studied. Talk to your pharmacist before starting.

Tribulus Maximus 250 by LifeLink: Common Questions

Does Tribulus Maximus 250 by LifeLink interact with any medications?
Yes. Based on its ingredients, Tribulus Maximus 250 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 Maximus 250 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 may affect hormones and its safety in pregnancy isn't established, so avoid it while pregnant. Also skip it while breastfeeding because we don't have reliable safety data. Talk to your doctor about other options.
What does tribulus do for sexual dysfunction?
Clinical evidence suggests tribulus is possibly effective for sexual dysfunction, meaning some people may see benefit. It's not guaranteed to work for everyone, and results vary. Your doctor can discuss whether it's right for your situation.
Will this help me perform better athletically?
No. The evidence suggests tribulus is possibly ineffective for athletic performance, so it's unlikely to give you a sports edge.
What side effects should I watch for?
Most people tolerate it fine, but stomach upset—pain, cramping, nausea, diarrhea—can happen. Serious effects like liver or kidney injury and seizures are rare. If you develop severe symptoms, stop and seek medical attention.
How long is it safe to take tribulus?
Short-term use in healthy adults is generally well tolerated, but long-term safety data are limited. We don't have solid evidence on how safe it is to take indefinitely. Discuss duration with your pharmacist or doctor.
Can I take this with my blood pressure or diabetes medication?
Tribulus can lower blood pressure and blood sugar on its own, so combining it with these drugs carries a Moderate interaction risk. You could end up with dangerously low pressure or blood sugar. Check with your pharmacist before adding this product.
