HelloPharmacist Scorecard of Blood Sugar Balance 335 mg by Eclectic Herb

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

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 5 active ingredients.
  • “Proprietary Blend Of Freeze-Dried Concentrated” is a proprietary blend — the label gives one combined amount (670 mg) without saying how much of each component you get.

This product contains 5 active ingredients, all in freeze-dried concentrated form: bitter melon fruit, green bean pod, huckleberry leaf (also called bilberry), prickly pear cactus leaf pad, and devil's club root bark. Each is meant to support blood sugar balance through different plant compounds.

The capsule itself contains hypromellose, an inactive ingredient that forms the capsule shell.

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: Blood sugar balance and support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, Hypercholesterolemia, Hyperlipidemia, Blood glucose control — and 2 related terms.
  • The strongest evidence on file: Prickly Pear Cactus is rated "Possibly Effective" for Diabetes (Natural Medicines).
  • Also on file: Bilberry is rated "Insufficient Reliable Evidence To Rate" for Diabetes, Hyperlipidemia, Impaired glucose tolerance (prediabetes), Metabolic syndrome.
  • Also on file: Bitter Melon is rated "Insufficient Reliable Evidence To Rate" for Diabetes, Impaired glucose tolerance (prediabetes).

The evidence for most of these ingredients is limited. Bitter melon for diabetes has insufficient reliable evidence to rate — we don't have solid proof it works for that purpose.

Huckleberry (bilberry) is rated possibly ineffective for night vision and has insufficient evidence for other uses listed. Prickly pear cactus is rated possibly effective for diabetes, making it the only ingredient in this blend with some positive evidence for blood sugar support.

Devil's club and green bean pod have no effectiveness ratings on file.

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Bitter melon is generally well tolerated as food, but at supplement doses it may lower blood sugar and cause stomach upset. The most common side effects are gastrointestinal — heartburn, nausea, vomiting, diarrhea, constipation, and abdominal discomfort occurred in about 3–16% of people in studies.

Rare cases of kidney problems have been reported with long-term high-dose bitter melon extract. Huckleberry and prickly pear are generally well tolerated orally; huckleberry may darken your stools and tongue temporarily, and prickly pear may cause mild diarrhea or digestive upset.

Devil's club has limited human safety data and may cause diarrhea, nausea, vomiting, or lightheadedness. Pregnancy and breastfeeding data vary by ingredient — bitter melon and prickly pear are traditionally avoided in pregnancy, and safety while nursing is not established for most ingredients here.

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?
  • 3 of the 4 matched ingredients can interact with medications — Bilberry, Bitter Melon, Prickly Pear Cactus.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 464 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 medications against Moderate-severity interactions: antidiabetes drugs (risk of low blood sugar), blood thinners and antiplatelet drugs, P-glycoprotein substrates, and certain cancer medications including pazopanib and erlotinib. If you take any of these, discuss it with your pharmacist first.

Bitter Melon Fruit Concentrate, Freeze-Dried3 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.

Likelihood Possible Evidence D
Bitter Melon Fruit Concentrate, Freeze-Dried full monograph & interactions

Huckleberry Leaf Concentrate, Freeze-Dried4 drug types · 275 drugs

Anticoagulant/Antiplatelet Drugs

Theoretically, bilberry fruit extract might increase the risk of bleeding when taken with anticoagulant or antiplatelet drugs.
In vitro, animal, and clinical research suggest that anthocyanidin extracts from bilberry can inhibit platelet aggregation.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, bilberry leaf or fruit extract may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Animal research suggests that bilberry leaf extract might have blood glucose-lowering activity. Also, one small clinical trial in patients with type 2 diabetes shows that taking bilberry fruit extract 470 mg as a single dose prior to an oral glucose tolerance test lowers plasma glucose levels when compared with placebo.

Likelihood Possible Evidence D
Cytochrome P450 2E1 (Cyp2E1) Substrates

Theoretically, bilberry fruit extract might decrease levels of drugs metabolized by CYP2E1.
Animal research shows that exposure to small concentrations of bilberry extract in drinking water for around one month increased CYP2E1 activity by 31%. However, exposure over a 2-month period did not increase CYP2E1 activity. This effect has not been reported in humans.

Likelihood Possible Evidence D
Erlotinib (Tarceva)

Theoretically, bilberry fruit extract might reduce the efficacy of erlotinib.
In vitro research suggests that bilberry fruit extract and its constituents, delphinidin and delphinidin-3-O-glucoside, inhibit the activity of erlotinib. This interaction has not been reported in humans.

Likelihood Possible Evidence D
Huckleberry Leaf Concentrate, Freeze-Dried full monograph & interactions

Prickly Pear Leaf Pad Concentrate, Freeze-Dried1 drug type · 86 drugs

Antidiabetes Drugs

Combining prickly pear cactus with antidiabetes drugs might increase the risk of hypoglycemia.
Case reports show that combining prickly pear cactus with antidiabetes drugs such as chlorpropamide, glyburide, glipizide, and metformin can increase the risk of hypoglycemia in patients with type 2 diabetes. Advise patients to monitor glucose levels closely. Dose adjustments may be necessary.

Blood Sugar Balance 335 mg by Eclectic Herb: Common Questions

Does Blood Sugar Balance 335 mg by Eclectic Herb interact with any medications?
Yes. Based on its ingredients, Blood Sugar Balance 335 mg has a known interaction with 464 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Blood Sugar Balance 335 mg contains 5 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is 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 on diabetes medication?
Not without checking with your pharmacist or doctor first. Bitter melon, huckleberry, and prickly pear all can lower blood sugar on their own, so combining them with diabetes drugs raises your risk of dangerously low blood sugar. Your prescriber needs to know you're considering this.
What are the most common side effects?
Gastrointestinal upset is the main one — heartburn, nausea, diarrhea, constipation, and stomach discomfort happen in a small number of people who take bitter melon. Huckleberry may darken your stools and tongue, and prickly pear may cause mild diarrhea or bloating. These are usually mild and temporary.
Is this safe during pregnancy or breastfeeding?
Bitter melon and prickly pear are traditionally avoided during pregnancy due to potential harmful effects. Safety while breastfeeding hasn't been established for most ingredients in this blend, so talk with your doctor or pharmacist before using it if you're pregnant or nursing.
Does this actually work for blood sugar?
The evidence is mixed. Prickly pear cactus is rated possibly effective for diabetes. Bitter melon and huckleberry don't have reliable evidence to prove they work for blood sugar control, even though they're included in the blend.
Why does the product list 457 medication interactions?
That's the total count of individual medications affected across all the checked ingredients — bitter melon, huckleberry, and prickly pear each interact with several drug classes (diabetes drugs, blood thinners, cancer medications, and others), which adds up quickly when you count every single prescription in those categories.
