HelloPharmacist Scorecard of Tribulus Extract 1300 mg by eXplicit Supplements

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 Sep 17, 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 powder at 1,300 mg per capsule. Tribulus is a plant extract traditionally used to support sexual function and athletic performance.

The capsules also contain cellulose and rice flour as inactive ingredients.

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: sexual function, testosterone, energy and mood.
  • We looked for evidence on: Erectile dysfunction (ED), Sexual dysfunction, Male infertility, Premature ejaculation, Athletic performance, Chronic fatigue syndrome (CFS) — 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 "Possibly Ineffective" for Athletic performance.
  • Also on file: Tribulus is rated "Insufficient Reliable Evidence To Rate" for Chronic fatigue syndrome (CFS), Erectile dysfunction (ED), Premature ejaculation, Male infertility.

The evidence shows tribulus is possibly effective for sexual dysfunction, though the data isn't definitive. For athletic performance, the evidence points toward possibly ineffective — meaning it's unlikely to boost your workout results.

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

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 by healthy adults, but long-term safety data and product quality information are limited. Gastrointestinal side effects like abdominal pain, cramping, nausea, vomiting, diarrhea, and constipation can occur, though in one study these complaints happened at similar rates in both tribulus and placebo groups.

Rare serious adverse effects including liver and kidney injury, seizures, and chronic painful erection have been reported. The safety data advises against use during pregnancy because it may affect hormones and safety hasn't been established.

You should also avoid tribulus while breastfeeding due to lack of reliable safety information.

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, double-check with your doctor or pharmacist if you take blood pressure medications (antihypertensives), diabetes drugs, or lithium. All three 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 might appeal to you if you're exploring natural support for sexual function, though the evidence is modest. If you take blood pressure medication, diabetes drugs, or lithium, tribulus is not a good fit — talk with your doctor or pharmacist before considering it.

Because long-term safety data are thin, keep your healthcare provider in the loop about how you're tolerating it.
