HelloPharmacist Scorecard of Jambu by Herbal Hills

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 capsule contains one active ingredient: a blend of jambolan seed extract and jambolan seed powder. Jambolan is a tropical fruit traditionally used in Ayurvedic medicine, and this product concentrates its seeds for supplement form.

The capsule itself is made from HPMC (a plant-based capsule material) and silicon dioxide, an inert filler.

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 Jambolan product and its label doesn't state a use — see Jambolan'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 jambolan isn't established in our data. We hold insufficient reliable evidence to rate it for diabetes support or for venous leg ulcers — the two uses we have effectiveness data for.

That doesn't mean it doesn't work; it means rigorous human trials are lacking or limited. If you're thinking about using this for a specific health goal, ask your pharmacist or doctor what the current research actually shows.

The evidence, ingredient by ingredient Jambolan

How safe is it?

Some data gaps
Safety Information · database check
Some gaps

Safety data exists for these ingredients, but with some important gaps.

Why this rating?
  • We hold adverse-effect (side-effect) data for 0 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.

Jambolan fruit is commonly eaten as food, but supplement doses are much more concentrated and aren't well studied — so there's a caution flag there. For pregnancy, the safety data isn't strong enough; the guidance advises against taking jambolan supplements during pregnancy.

Breastfeeding safety is also unknown, so supplement use isn't recommended then either. If you're pregnant, planning pregnancy, or breastfeeding, talk with your pharmacist or doctor before starting.

Side effects, ingredient by ingredient Jambolan

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 — Jambolan.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 186 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 this product, check with your pharmacist if you take diabetes medications (including sitagliptin/Januvia) or any drugs processed by the liver enzyme CYP2C9 — a group that includes many common blood thinners and other medications. Jambolan can affect how your body handles these drugs.

The bottom line

Scorecard at a glanceFully disclosed formula with no assessable stated purpose. Moderate medication interactions have been identified, and some safety-information gaps remain.

Jambu is worth considering if you're interested in traditional jambolan support and you don't take diabetes drugs or medications metabolized by CYP2C9. If you're on any prescription medication — especially blood sugar medicine — check it against our interaction tool before you start.

Pregnant or breastfeeding? Skip this one until you've talked to your doctor.

Jambu seed extract & Jambu seed powder blend3 drug types · 186 drugs

Antidiabetes Drugs

Animal research shows that jambolan seed and bark extracts can lower blood glucose levels. Theoretically, jambolan might have additive effects when used with antidiabetes drugs. This might increase the risk of hypoglycemia in some patients. Monitor blood glucose levels closely.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

There is some in vitro evidence that jambolan can inhibit CYP2C9. Theoretically, concomitant use of jambolan with CYP2C9 substrates may increase levels of drugs metabolized by CYP2C9.

Likelihood Possible Evidence D
Sitagliptin (Januvia)

Animal research shows that jambolan seed extract reduces the sitagliptin maximum plasma concentration and area under the curve by 39% and 22%, respectively. However, blood glucose levels were actually reduced to a greater extent in mice taking jambolan and sitagliptin in combination when compared with either product taken alone. Theoretically, jambolan seed extract might alter the clearance of sitagliptin, although this may not alter the clinical effects of sitagliptin.

Jambu by Herbal Hills: Common Questions

Does Jambu by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Jambu has a known interaction with 186 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Jambu 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 Jambu if I'm pregnant?
No. The safety data advises against jambolan supplements during pregnancy. Talk with your doctor or pharmacist if you're pregnant or planning to become pregnant.
Is it safe to breastfeed while taking this?
No. Safety while breastfeeding isn't known, so jambolan supplements aren't recommended. Speak with your pharmacist or doctor for personalized advice.
What is jambolan?
Jambolan is a tropical fruit used in traditional Ayurvedic medicine. The fruit itself is eaten as food, but this supplement concentrates the seed powder and extract into capsule form for a higher dose than you'd get from eating the fruit.
Does jambolan work for blood sugar?
Animal studies suggest jambolan seed may lower blood glucose, but we don't have enough reliable human research yet to say whether it works for diabetes support. The evidence isn't established in our data.
Can I take this with my diabetes medication?
Not without talking to your pharmacist first. Jambolan can lower blood sugar on its own, so combining it with diabetes drugs might lower your blood sugar too much. Your doctor or pharmacist needs to review your specific medications and may want to monitor your glucose levels.
Are there any side effects from jambolan?
We don't have documented adverse effects from the studies in our data. That said, concentrated supplement doses of jambolan aren't well studied overall, so the full picture of side effects isn't clear.
