HelloPharmacist Scorecard of Glucose Support Chocolate Flavor by TerraVita

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 Aug 6, 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 3 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label gives one combined amount (0.13 mL) without saying how much of each component you get.

Glucose Support Chocolate Flavor contains 3 active ingredients: bilberry glycerite liquid extract, kidney bean pod glycerite liquid extract, and olive glycerite liquid extract. These are delivered in liquid form and flavored with chocolate.

The product also contains glycerin and chocolate flavor as inactive ingredients.

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.

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

The evidence for bilberry's effects on blood sugar or glucose control isn't established in the data we hold — we have ratings only for night vision (possibly ineffective) and several other conditions with insufficient evidence. Kidney bean pod extract and olive extract have no effectiveness ratings on file for glucose support or blood sugar.

Before you start this supplement, talk with your doctor about whether the evidence supports its use for your specific goal.

The evidence, ingredient by ingredient Bilberry Olive

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Bilberry fruit is generally well tolerated and likely safe in pregnancy and lactation. The most common side effects are dark-colored stools, flatulence, and mild stomach discomfort — some users also report temporary discoloration of the tongue or teeth.

Olive extract is also generally well tolerated, with occasional headache or stomach discomfort reported. Olive tree pollen can trigger seasonal allergies in sensitive people.

Both ingredients have limited long-term safety data in concentrated supplement form, so the facts advise caution with doses beyond typical food amounts.

Side effects, ingredient by ingredient Bilberry Olive

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 2 matched ingredients can interact with medications — Bilberry.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs; diabetes medications.
  • For scale: 275 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.

Check with your doctor or pharmacist if you take blood thinners or antiplatelet drugs — bilberry may increase bleeding risk. Diabetes medications need discussion too, since bilberry may lower blood sugar and raise the risk of hypoglycemia.

If you take erlotinib (Tarceva) for cancer, alert your provider, as bilberry may reduce its effectiveness. CYP2E1 substrates (certain other drugs your liver processes in a specific way) may also be affected.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with glucose management, but the evidence isn't well established in our data. If you take blood thinners, diabetes drugs, or certain cancer medications, you'll want to check with your doctor or pharmacist before starting it — the bilberry content carries a moderate interaction risk with those drug types.

Olive and kidney bean pod extracts add to the formula, though we have limited interaction data on the bean ingredient. It's generally well tolerated, but discuss it with your own healthcare provider to make sure it's right for you.

Bilberry Glycerite Liquid Extract4 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.

How can one product interact with so many drugs?
Glucose Support Chocolate Flavor contains 3 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.
Is this safe to take if I'm pregnant or breastfeeding?
Bilberry is rated likely safe in pregnancy and lactation. However, we don't have safety data on file for kidney bean pod extract in pregnancy or breastfeeding, and olive extract shows no pregnancy/lactation rating in our data. Talk with your doctor or pharmacist for personalized advice, especially since this product is concentrated supplement form rather than food amounts.
What side effects might I notice?
The most common are dark-colored stools, flatulence, and mild stomach discomfort from the bilberry. Some people also report temporary discoloration of the tongue or teeth. Olive extract may occasionally cause headache or mild stomach discomfort. Most users tolerate it well.
Does bilberry actually help with blood sugar?
Animal research and a small clinical trial suggest bilberry leaf or fruit extract may help lower blood sugar, but the evidence in our data isn't rated as established. That's why it's important to discuss this product with your doctor if you have diabetes or take diabetes medications — the potential interaction with those drugs needs to be managed.
Can I take this with my other medications?
That depends on what you take. Bilberry in this product interacts with blood thinners, diabetes drugs, certain cancer medications, and some other drug types. Use the medication checker on this page to look up your prescriptions, and then talk with your doctor or pharmacist before starting.
What is kidney bean pod extract supposed to do?
