HelloPharmacist Scorecard of Tongkat Ali Complex by Evlution Nutrition

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Tongkat Ali Complex contains 2 active ingredients: Tongkat Ali root extract and Tribulus terrestris powder. Tongkat Ali root extract is used to support sexual desire and general wellness.

Tribulus terrestris is traditionally used for sexual function and athletic performance. The product also contains inactive ingredients—hypromellose, dicalcium phosphate, stearate, and silicon dioxide—which serve as capsule material and flow agents.

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: supports men's health and vitality.
  • We looked for evidence on: Age-related testosterone deficiency, Athletic performance, Erectile dysfunction (ED), Exercise-induced muscle damage, Male Infertility, Muscle strength — and 4 related terms.
  • The strongest evidence on file: Tribulus is rated "Possibly Effective" for Sexual dysfunction (Natural Medicines).
  • Also on file: Eurycoma Longifolia is rated "Possibly Effective" for Sexual desire.
  • Also on file: Tribulus is rated "Possibly Ineffective" for Athletic performance.

For sexual desire, Tongkat Ali root extract is rated possibly effective based on available research. Tribulus terrestris is also rated possibly effective for sexual dysfunction.

For athletic performance, Tongkat Ali root extract is rated possibly ineffective. The evidence for Tribulus and athletic performance is similarly not strong.

For other claimed uses—back pain, osteoporosis, and diabetes with Tongkat Ali, and benign prostatic hyperplasia with Tribulus—we don't have enough reliable evidence to rate either ingredient.

The evidence, ingredient by ingredient Eurycoma Longifolia 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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both ingredients are generally well tolerated in short-term studies, but long-term safety data are limited and product quality varies. The most important safety concern is that both ingredients may raise testosterone levels.

If testosterone goes above the normal range, there's a risk of acne, insulin resistance, liver damage, and other side effects. Avoid this product during pregnancy because of possible hormonal effects and insufficient safety data.

Avoid it while breastfeeding as well—there isn't enough reliable safety information. Tribulus carries rare reports of serious side effects including liver and kidney injury, seizures, and painful erection; these are uncommon but possible.

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?
  • 2 of the 2 matched ingredients can interact with medications — Tribulus, Eurycoma Longifolia.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 501 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 Tongkat Ali Complex, double-check with your pharmacist if you're on propranolol (a moderate interaction), any blood pressure medication or diabetes drug (moderate interactions with tribulus), or lithium (moderate interaction with tribulus). Minor theoretical interactions also exist with medications that rely on CYP1A2, CYP2C19, or CYP2A6 enzymes, and with testosterone therapy.

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.

This product is used for sexual function and athletic support. If you take propranolol, blood pressure medication, diabetes medication, or lithium, talk to your pharmacist before starting it—dosage adjustments may be needed.

If you're pregnant or breastfeeding, avoid this product. Testosterone-related side effects are a real concern if you're predisposed to them.

Tribulus terrestris, Powder3 drug types · 259 drugs

Antidiabetes Drugs

Taking tribulus with antidiabetes drugs might increase the risk of hypoglycemia.
Clinical research shows that Tribulus can lower blood glucose levels in adults with type 2 diabetes who are taking antidiabetes medications.

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.

Likelihood Probable Evidence D
Tribulus terrestris, Powder full monograph & interactions

Tongkat Ali Root Extract5 drug types · 248 drugs

Propranolol (Inderal)

Eurycoma longifolia can reduce the levels and clinical effects of propranolol.
A small clinical study in healthy persons shows that taking a single dose of a water-based Eurycoma longifolia extract 200 mg, in combination with a single dose of propranolol 80 mg, reduces the propranolol area under the curve (AUC) by 29%, reduces the peak concentration by 42%, and increases time to peak concentration by 86% when compared with control. Since the elimination half-life of propranolol did not change, it seems that Eurycoma longifolia alters the kinetics of propranolol by decreasing its absorption in the gut, and not by altering its metabolism. It is not known if separating administration will prevent this interaction.

Likelihood Probable Evidence A
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, Eurycoma longifolia might increase levels CYP1A2 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP1A2 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2A6 (Cyp2A6) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2A6 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2A6 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Cytochrome P450 2C19 (Cyp2C19) Substrates

Theoretically, Eurycoma longifolia might increase levels of CYP2C19 substrates.
In vitro research suggests that methanolic Eurycoma longifolia root extract weakly inhibits CYP2C19 enzymes. This effect has not been reported in humans.

Likelihood Possible Evidence D
Testosterone

Theoretically, Eurycoma longifolia may further increase levels of testosterone.
A clinical study in aging males with testosterone levels below 300 ng/dL shows that taking a specific water extract of Eurycoma longifolia roots (Physta; Biotropics Malaysia) 100-200 mg daily with breakfast for 12 weeks increases total testosterone levels by 8% to 11% when compared with placebo. It is unclear whether this increase would occur in individuals with normal testosterone levels.

Tongkat Ali Complex by Evlution Nutrition: Common Questions

Does Tongkat Ali Complex by Evlution Nutrition interact with any medications?
Yes. Based on its ingredients, Tongkat Ali Complex has a known interaction with 501 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Tongkat Ali Complex contains 2 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 this product actually improve sexual function?
Tongkat Ali root extract and Tribulus terrestris are both rated possibly effective for sexual desire and sexual dysfunction based on available research. Results aren't guaranteed and vary by person, so talk with your doctor if you have ongoing concerns.
Can I take this if I'm pregnant or breastfeeding?
No. The safety data advise against use during pregnancy because of possible hormonal effects. While breastfeeding, there isn't enough reliable safety information, so you should avoid it as well. Talk with your doctor if you have questions about timing.
What are the side effects I should watch for?
Both ingredients are generally well tolerated short-term, but side effects can include gastrointestinal complaints like nausea, cramping, and diarrhea (usually mild). The bigger concern is that either ingredient may raise testosterone—if it goes too high, you might develop acne, insulin resistance, or liver issues. Tribulus has rare reports of seizures and kidney injury.
Will this affect my blood pressure or blood sugar medication?
Yes—Tribulus can lower blood pressure and blood sugar on its own, so combined with your medications there's a risk of blood pressure dropping too low or blood sugar dropping too low (hypoglycemia). Your doctor or pharmacist may need to adjust your medication dose.
Is there a long-term safety concern with this product?
Long-term safety data are limited for both ingredients, and product quality can vary. While short-term studies show it's generally tolerated, we don't have solid evidence on what happens if you take it for months or years.
