HelloPharmacist Scorecard of Karelahills 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

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 2 active ingredients.
  • “{Bitter Gourd} Blend” is a proprietary blend — the label gives one combined amount (450 mg) without saying how much of each component you get.

Karelahills contains 2 active ingredients, both forms of bitter gourd: a fruit extract and a fruit powder. Bitter gourd (also called bitter melon) is a tropical plant used traditionally to support blood sugar and digestion.

The product also contains inactive ingredients — magnesium stearate, silica, and a gelatin capsule — that help hold it together and deliver the active ingredients.

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 Bitter Melon product and its label doesn't state a use — see Bitter Melon'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 we have on bitter gourd for the uses claimed here — amenorrhea, athletic performance, liver disease, constipation, diabetes, and indigestion — is insufficient to give it a reliable rating. That doesn't mean it doesn't work; it means the studies so far haven't been strong enough to say.

If you're interested in bitter gourd for a specific condition, talk with your pharmacist or doctor about what the latest research shows for your situation.

The evidence, ingredient by ingredient Bitter Melon

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.

Bitter gourd is generally well tolerated when used as food, but supplement doses can lower your blood sugar and cause stomach upset. Common side effects in clinical studies include heartburn, nausea, vomiting, diarrhea, constipation, gas, and belly discomfort — these occurred in about 3% to 16% of people who took it.

Rarely, very low blood sugar (hypoglycemic coma) and seizures in children have been reported. One case also documented kidney damage that developed over months of high-dose use and reversed after stopping the supplement.

Bitter gourd is traditionally avoided in pregnancy because seeds and high doses may cause harmful effects to the uterus. There isn't enough reliable safety data for breastfeeding, so it's best avoided then too.

Side effects, ingredient by ingredient Bitter Melon

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 — Bitter Melon.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 282 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 Karelahills, check whether you're on any diabetes medications (blood sugar pills or insulin), the cancer drug pazopanib, or any drugs that use P-glycoprotein to enter your cells — a category that spans many medications. All three are Moderate-severity interactions with bitter gourd.

Use the search tool on this page to look up your exact prescriptions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

Karelahills is worth discussing with your pharmacist if you're curious about bitter gourd for blood sugar or digestion — but only if you don't take diabetes drugs, certain cancer medications, or drugs that depend on a P-glycoprotein pump to work. If you take any prescription medications, check them against this product before you start, because the interaction list is long.

Pregnancy and breastfeeding are times to skip it.

{Bitter Gourd} Blend3 drug types · 282 drugs

Antidiabetes Drugs

Taking bitter melon with antidiabetes drugs might increase the risk of hypoglycemia.
Bitter melon can lower blood glucose levels and 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 Probable Evidence B
P-Glycoprotein Substrates

Theoretically, bitter melon might increase levels of P-glycoprotein substrates.
Bitter melon might inhibit the p-glycoprotein (P-gp) intestinal pump and increase intracellular levels of P-gp substrates. In vitro research in intestinal cells shows that 1-monopalmitin, a constituent of bitter melon, increases levels of daunomycin, a P-gp substrate. Additionally, drinking bitter melon juice has been associated with a case of acute pancreatitis in a patient who had been taking pazopanib, a P-gp substrate, for 8 years. Researchers theorize that inhibition of P-gp led to increased levels of pazopanib, resulting in pazopanib-induced pancreatitis.

Likelihood Possible Evidence D
Pazopanib (Votrient)

Theoretically, bitter melon might increase levels of pazopanib, potentially increasing the risk of adverse effects.
In one case, a 65-year-old patient taking pazopanib for 8 years for renal cell carcinoma experienced signs and symptoms consistent with acute pancreatitis 4 days after drinking bitter melon juice at a dose of 100-150 mL daily. The patient's symptoms, amylase levels, and lipase levels improved upon discontinuation of bitter melon and pazopanib. Pazopanib treatment was re-initiated with no further evidence of pancreatitis. Researchers theorize that inhibition of P-glycoprotein by bitter melon led to increased levels of pazopanib, a P-glycoprotein substrate, resulting in pazopanib-induced pancreatitis.

Karelahills by Herbal Hills: Common Questions

Does Karelahills by Herbal Hills interact with any medications?
Yes. Based on its ingredients, Karelahills has a known interaction with 282 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Karelahills 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 this if I'm pregnant?
The safety data advises against it. Bitter gourd seeds and high doses have traditionally been avoided in pregnancy because they may cause harmful effects. Talk with your doctor or pharmacist before using it if you're pregnant or planning to become pregnant.
Is it safe while breastfeeding?
There isn't enough reliable safety information to know either way. It's best avoided while breastfeeding. Chat with your pharmacist or doctor for personalized advice if you're considering it.
What are the most common side effects?
Gastrointestinal upset is most likely — heartburn, nausea, vomiting, diarrhea, constipation, gas, and belly discomfort. In clinical studies, these happened in about 3% to 16% of people taking bitter gourd. You might also feel dizzy, tired, or get a headache.
Does bitter gourd actually work for diabetes?
The evidence we have is insufficient to give it a reliable rating. That means the studies haven't been strong enough yet to say whether it helps. If you're interested in it for blood sugar control, ask your doctor or pharmacist what the latest research shows.
What is bitter gourd supposed to do?
Bitter gourd, also called bitter melon, is a tropical plant traditionally used to support blood sugar and digestion. Karelahills contains it in two forms — an extract and a powder.
Are there any fillers in this?
Yes. Besides the two forms of bitter gourd, the capsules contain magnesium stearate, silica, and gelatin — these are inactive ingredients that help keep the supplement together and make it easier to swallow.
