HelloPharmacist Scorecard of Banaba Leaf by Paradise

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 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: banaba leaf extract. Banaba is a plant traditionally used in herbal medicine, and its extract is what does the work in this capsule.

The capsule itself is made from a vegetarian cellulose material.

Does it work?

Couldn't assess
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
Not assessable

This is a single-ingredient Banaba product and its label doesn't state a use — see Banaba's own graded uses on its monograph.

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.

The evidence for banaba isn't established yet. For diabetes, impaired glucose tolerance (prediabetes), and metabolic syndrome, the data we hold rates it as having insufficient reliable evidence.

That doesn't mean it doesn't work — it means we don't have enough solid human studies to say either way.

The evidence, ingredient by ingredient Banaba

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.

Banaba extract is generally well tolerated in the short term, though long-term safety isn't well understood. In trials, side effects like dizziness, headache, tremor, weakness, stomach upset, and palpitations have been reported with a specific combination product containing banaba and another herb, but it's unclear which ingredient (or the mix) caused them.

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

Side effects, ingredient by ingredient Banaba

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 — Banaba.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 299 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 your blood sugar–lowering drugs (antidiabetes medications) and blood pressure medications with your doctor or pharmacist — banaba may add to their effects. Also check whether you take any drugs that rely on OATP transporters for absorption, as banaba may interfere with how well they're absorbed.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

If you're interested in banaba for blood sugar or metabolic health, talk it over with your doctor or pharmacist first — especially if you take diabetes or blood pressure medications, since the interactions could be significant. The long-term safety picture isn't clear, and it's not recommended during pregnancy or breastfeeding.

Your own healthcare provider can weigh the evidence and your personal health history.

Organic Anion-Transporting Polypeptide Substrates (Oatp)

Theoretically, concomitant use of banaba with substrates of OATP might reduce the bioavailability of the OATP substrate.

Banaba Leaf by Paradise: Common Questions

Does Banaba Leaf by Paradise interact with any medications?
Yes. Based on its ingredients, Banaba Leaf has a known interaction with 299 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Banaba Leaf 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.
Does banaba actually lower blood sugar?
Research suggests it can, but we don't have enough solid human studies yet to say how well it works or for whom. If you're diabetic or prediabetic and interested in trying it, your doctor or pharmacist can help you weigh the evidence for your situation.
What side effects might I feel?
Banaba extract itself is generally well tolerated, but dizziness, headache, tremor, weakness, stomach upset, and palpitations have been reported with a specific combination product. It's unclear whether banaba alone caused these or the other herb in that product did.
Is it safe if I'm pregnant or breastfeeding?
No — the safety data advises against it during pregnancy and while nursing because there isn't enough information to know either way. Talk with your doctor or pharmacist about safer alternatives.
How long can I safely take this?
Short-term use appears well tolerated, but long-term safety hasn't been well studied. Discuss duration with your doctor or pharmacist, especially if you're managing a chronic condition.
Can I take this with my blood pressure medication?
Not without checking first — banaba can lower blood pressure on its own, so combining it with blood pressure drugs could drop your pressure too much. Your doctor or pharmacist needs to know about both before you start.
