HelloPharmacist Scorecard of Tribulus Gold 750 MG by Precision Engineered

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.

Tribulus Gold contains one active ingredient: tribulus, a plant extract, at 750 mg per capsule. The capsule itself is made from gelatin and vegetable cellulose, which are inert fillers and binders with no active role.

Does it work?

Leans against
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
Leans against

The strongest graded evidence we hold for the stated purpose leans against a benefit.

Why this rating?
  • The label markets this product for: athletic performance and muscle building.
  • We looked for evidence on: Athletic performance, Exercise-induced muscle damage, Strength and endurance, Recovery, Sports nutrition.
  • The closest evidence on file: Tribulus is rated "Possibly Ineffective" for Athletic performance (Natural Medicines).
  • Also on file: Tribulus is rated "Insufficient Reliable Evidence To Rate" for Exercise-induced muscle damage.

Tribulus is possibly effective for sexual dysfunction — that's the one use where clinical evidence exists. For athletic performance, the evidence points toward it being possibly ineffective.

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 short-term in healthy adults, though 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 rates were similar to placebo.

Rare serious adverse effects have been reported, including liver and kidney injury, seizures, and a case involving lower-limb weakness and acute kidney injury after very high intake. Avoid tribulus during pregnancy because it may affect hormones and safety is not established, and avoid it while breastfeeding due to lack of reliable 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.

Check with your doctor or pharmacist before taking this if you're on blood pressure medication, diabetes medication, or lithium — all three carry Moderate risk of serious interactions. Blood pressure drugs and tribulus together could drop your pressure too low, diabetes drugs could trigger low blood sugar, and lithium levels could rise to unsafe amounts.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with graded evidence leaning against its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Tribulus may be worth considering if you're exploring options for sexual dysfunction, though the evidence is modest. If you take blood pressure medication, diabetes medication, or lithium, you'll need to check with your doctor or pharmacist before starting — tribulus can lower blood pressure and blood sugar, and may raise lithium levels.

Talk it over with your own healthcare provider before adding this to your routine.

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 Gold 750 MG by Precision Engineered: Common Questions

Does Tribulus Gold 750 MG by Precision Engineered interact with any medications?
Yes. Based on its ingredients, Tribulus Gold 750 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 Gold 750 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.
Can I take Tribulus Gold if I'm pregnant or breastfeeding?
No. The safety data advises against tribulus during pregnancy because it may affect hormones and safety is not established. Avoid it while breastfeeding as well, since there isn't enough reliable safety information.
What side effects might I experience?
Most people tolerate it well, but gastrointestinal upset — stomach pain, cramping, nausea, vomiting, diarrhea, or constipation — can happen. Rare serious effects including liver or kidney injury and seizures have been reported, though they're uncommon.
Does Tribulus Gold actually work for sexual dysfunction?
The evidence says it's possibly effective — meaning there's some clinical research supporting it, but it's not a guaranteed fix. Results vary from person to person.
Will it help me build muscle or improve athletic performance?
No — the evidence we have suggests it's possibly ineffective for athletic performance.
How long is it safe to take?
Short-term use appears well tolerated in healthy adults, but long-term safety data are limited. Talk with your doctor about how long you plan to use it.
Are there any fillers or other inactive ingredients I should know about?
Yes, the capsule contains gelatin and vegetable cellulose as inactive ingredients — these are binders and fillers with no active effect.
