HelloPharmacist Scorecard of Glucose Support Strawberry 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.

TerraVita Glucose Support contains 3 active ingredients in liquid form, all delivered as glycerite extracts (plant material mixed with glycerin). Bilberry fruit extract is traditionally used for eye and circulation health, kidney bean pod extract may be intended to support healthy glucose levels, and olive extract is included for antioxidant support.

The product also contains glycerin and strawberry 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 and glucose support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome, Hyperglycemia, Insulin resistance.
  • 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 what this product can actually do is limited. Bilberry's most studied claim—that it sharpens night vision—is rated possibly ineffective based on the data we hold.

For the other conditions the ingredients are often marketed for (age-related cognitive decline, macular degeneration, heart health, cholesterol), the evidence is insufficient to know whether they work. Kidney bean pod extract hasn't been rated in our data, and olive extract has no established effectiveness for the conditions listed.

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 when eaten as food, but concentrated supplements have limited long-term safety data, so caution is advised. The most common side effects are dark or discolored stools, gas, and mild stomach discomfort—a small number of trial participants reported mild-to-moderate flatulence and temporary digestive upset.

Olive extract is also generally well tolerated; the most common side effects are headache and stomach discomfort, though one trial participant reported acne. Bilberry is rated likely safe in pregnancy and lactation, but we hold no pregnancy or lactation data for kidney bean pod or olive, so if you're pregnant or nursing, talk with your doctor or pharmacist about whether this product is right for you.

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.

Before you take this product, double-check with your pharmacist or doctor if you're on blood thinners (anticoagulants or antiplatelet drugs), diabetes medications, erlotinib (Tarceva) or other cancer drugs, or any medications metabolized through the CYP2E1 enzyme. Bilberry has documented moderate-severity interactions with all of these.

No interactions are documented for the kidney bean pod extract ingredient we could not check.

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 appeal to someone looking for natural glucose support, but the evidence that it works isn't solid. If you take blood thinners, diabetes medications, cancer drugs, or other prescriptions, you need to check your exact medications before starting because bilberry can interact with many of them.

Talk with your doctor or pharmacist about whether it's appropriate for you and whether it might interfere with anything you're already taking.

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.

Glucose Support Strawberry Flavor by TerraVita: Common Questions

Does Glucose Support Strawberry Flavor by TerraVita interact with any medications?
Yes. Based on its ingredients, Glucose Support Strawberry Flavor has a known interaction with 275 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Glucose Support Strawberry 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 on warfarin or other blood thinners?
Bilberry in this product may increase bleeding risk when combined with blood thinners, so this is a serious concern. Do not start this product without clearing it with your doctor or pharmacist first—they need to weigh the risks for your specific situation.
Can I take this if I'm on diabetes medication?
Bilberry may lower blood sugar on its own, which could push your levels too low when combined with diabetes drugs. Talk with your doctor or pharmacist before you start to make sure your medications and this product won't work against each other.
What are the most common side effects?
Bilberry commonly causes dark or discolored stools, gas, and mild stomach discomfort. A small number of people reported temporary digestive upset in trials. Olive extract may cause headache or stomach discomfort. These are generally mild and tend to pass.
Does bilberry really help with night vision?
No—the evidence shows it's possibly ineffective for night vision, so that's not a reliable reason to take it. For the other conditions bilberry is marketed for, there's not enough reliable evidence to say whether it works.
Is it safe in pregnancy or while breastfeeding?
Bilberry is rated likely safe during pregnancy and lactation. We don't have safety data on file for kidney bean pod or olive in pregnancy and lactation, so talk with your doctor or pharmacist for personalized advice if you're pregnant or nursing.
What's in this besides the active ingredients?
The inactive ingredients are glycerin (the carrier for the plant extracts) and strawberry flavor. There are no other fillers or binders.
