HelloPharmacist Scorecard of Banaba 1.5% Extract Powder by TerraVita Premium Collection

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

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 extract powder at 1.5% strength. Banaba is a plant extract that's been studied for its potential effects on blood sugar and blood pressure.

The powder form means there are no inactive fillers or binders — what you're getting is the extract itself.

Does it work?

Not established
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 established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Banaba's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: blood sugar support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, Type 2 diabetes, Hyperglycemia.
  • The closest evidence on file: Banaba is rated "Insufficient Reliable Evidence To Rate" for Diabetes (Natural Medicines).
  • Also on file: Banaba is rated "Insufficient Reliable Evidence To Rate" for Impaired glucose tolerance (prediabetes), Metabolic syndrome.

The evidence for banaba isn't established yet. The data we hold shows insufficient reliable evidence to rate it for diabetes, impaired glucose tolerance (prediabetes), or metabolic syndrome.

That doesn't mean it doesn't work — it means the studies so far haven't been strong enough to draw clear conclusions. If you're considering it for any of these conditions, talk with your doctor about whether it makes sense alongside your other treatments.

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 appears to be well tolerated in the short-term studies we have. However, we don't have enough data on long-term safety, so use caution if you're thinking about taking this for weeks or months on end.

Side effects reported in one product containing banaba and another plant (Padang cassia) included dizziness, headache, tremor, weakness, sweating, stomach upset, heart palpitations, and a shaky feeling — though it's unclear which ingredient caused them. For pregnancy and breastfeeding, the safety data isn't there: avoid it during pregnancy and do not use while nursing.

If you're pregnant, planning to become pregnant, or breastfeeding, talk with your doctor or pharmacist before considering this product.

Banaba 1.5% Extract Powder by TerraVita Premium Collection: Common Questions

Does Banaba 1.5% Extract Powder by TerraVita Premium Collection interact with any medications?
Yes. Based on its ingredients, Banaba 1.5% Extract Powder 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 1.5% Extract Powder 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.
Will banaba lower my blood sugar if I'm already on diabetes medication?
Possibly. Banaba research suggests it can lower blood glucose, and combining it with a diabetes drug might cause your blood sugar to drop too far. Don't start this without checking with your doctor or pharmacist first — they can help you decide if a dose adjustment is needed or if it's safe for you at all.
Can I take banaba if I'm pregnant?
No. There isn't enough safety data during pregnancy, so it's best avoided. If you're pregnant or planning to become pregnant, talk with your doctor or pharmacist before using this product.
Is it safe while I'm breastfeeding?
No. We don't have reliable safety information for nursing, so avoid use while breastfeeding. Check with your doctor or pharmacist if you have questions.
What are the most common side effects?
One product containing banaba plus another plant reported dizziness, headache, tremor, weakness, sweating, stomach upset, heart palpitations, and shakiness — but it's unclear which ingredient caused them. Banaba extract by itself appears well tolerated in short-term studies, though long-term safety isn't established.
How much evidence is there that banaba works for prediabetes?
Not enough to rate it yet. The studies we have show insufficient reliable evidence for diabetes, prediabetes, or metabolic syndrome. More research is needed before we can say how well it works.
