HelloPharmacist Scorecard of Tongkat Ali 200 mg by NutraBio

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.

This product contains one active ingredient: LJ100, a water-based extract of Eurycoma longifolia root, often called Tongkat Ali. It's a traditional herbal root used primarily for sexual health.

The capsule also contains two inactive ingredients—hypromellose and water—which are the capsule material and a processing agent.

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: male vitality and testosterone support.
  • We looked for evidence on: Age-related testosterone deficiency, Athletic performance, Erectile dysfunction (ED), Male Infertility, Muscle strength, Sexual desire — and 4 related terms.
  • The strongest evidence on file: Eurycoma Longifolia is rated "Possibly Effective" for Sexual desire (Natural Medicines).
  • Also on file: Eurycoma Longifolia is rated "Possibly Ineffective" for Athletic performance.
  • Also on file: Eurycoma Longifolia is rated "Insufficient Reliable Evidence To Rate" for Erectile dysfunction (ED), Muscle strength, Age-related testosterone deficiency, Male Infertility.

The evidence for Eurycoma longifolia shows it is possibly effective for sexual desire. For athletic performance, the data suggests it is possibly ineffective.

For back pain, osteoporosis, and diabetes, there isn't enough reliable evidence in our data to say whether it works or doesn't.

The evidence, ingredient by ingredient Eurycoma Longifolia

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.

Eurycoma longifolia is generally well tolerated in short-term studies, but long-term safety and quality control of products aren't well established. The main safety concern is testosterone — the supplement can raise your testosterone levels, and if they go too high, you could develop acne, insulin resistance, liver stress, and other testosterone-related side effects.

The safety data advises against use during pregnancy and breastfeeding because there isn't enough information to know whether it's safe for you or your baby.

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 — Eurycoma Longifolia.
  • The most serious interaction on file is rated Moderate.
  • For scale: 248 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 you take this, double-check with us if you're on propranolol (Inderal) — this is the most serious concern. Also let us know if you take any medications that use your liver's enzyme systems (CYP1A2, CYP2C19, or CYP2A6 substrates) or testosterone replacement therapy, since the supplement could affect how they work.

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.

Tongkat Ali may help with sexual desire if you're interested in that use, but don't take it if you're on propranolol without checking with your pharmacist first. It's also not for pregnancy or breastfeeding, and anyone taking medications metabolized by the liver should verify their drug list before starting.

Talk to your pharmacist about whether it's right for your situation.

LJ1005 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.

LJ100 is a water-based extract of Eurycoma longifolia root, the plant commonly called Tongkat Ali. It's the active ingredient in this supplement.
