HelloPharmacist Scorecard of Advanced Glucose Support by OL Olympian Labs

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 3 of its 3 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Advanced Glucose Support contains three active ingredients. Benfotiamine is a form of vitamin B1 that your body absorbs more readily than standard thiamine.

Gymnema extract comes from an herb traditionally used to support healthy blood sugar levels. Thiamine HCl is standard vitamin B1, important for how your body uses glucose and supports nerve function.

The product also contains inactive ingredients: a vegetarian capsule, rice flour, microcrystalline cellulose, silicon dioxide, and ascorbyl palmitate (a form of vitamin C used as a preservative).

Does it work?

Strong 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
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Blood sugar and glucose metabolism support.
  • We looked for evidence on: Diabetes, Impaired glucose tolerance (prediabetes), Dyslipidemia, Metabolic syndrome, Diabetic neuropathy, Peripheral neuropathy — and 3 related terms.
  • The strongest evidence on file: Thiamine is rated "Effective" for Thiamine deficiency (Natural Medicines).
  • Also on file: Benfotiamine is rated "Possibly Effective" for Diabetic neuropathy.
  • Also on file: Gymnema is rated "Insufficient Reliable Evidence To Rate" for Diabetes, Impaired glucose tolerance (prediabetes), Metabolic syndrome.

The evidence on how well this product works is mixed. Thiamine HCl is effective for thiamine deficiency and for Wernicke-Korsakoff syndrome, a serious thiamine-deficiency condition.

It's possibly effective for painful menstrual periods (dysmenorrhea). Benfotiamine is possibly effective for diabetic nerve damage (neuropathy) but appears possibly ineffective for diabetic kidney damage.

For gymnema extract, the evidence isn't established in our data — we hold insufficient reliable evidence to rate it for diabetes, prediabetes, metabolic syndrome, or obesity. So while these ingredients have some research backing, how well the combination works for "glucose support" as a whole isn't established in the data we have.

The evidence, ingredient by ingredient Benfotiamine Gymnema Thiamine

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Thiamine HCl is generally very safe when taken by mouth in normal doses and is actually needed during pregnancy and breastfeeding — use only at doses your doctor recommends. Benfotiamine is generally well tolerated in studies, but long-term safety isn't fully known; the data advises against it during pregnancy, and caution is advised while breastfeeding.

A small number of trial participants reported allergic skin reactions or mild digestive discomfort, at rates no higher than placebo. Gymnema extract is generally well tolerated short-term, but it can lower your blood sugar.

Rare but serious cases of liver inflammation (hepatitis) have been reported with gymnema use. The safety data advises against gymnema during pregnancy and breastfeeding due to insufficient data.

Side effects, ingredient by ingredient Benfotiamine Gymnema Thiamine

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?
  • 2 of the 3 matched ingredients can interact with medications — Gymnema, Thiamine.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: diabetes medications.
  • For scale: 854 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.

If you take antidiabetes drugs (like metformin, insulin, sulfonylureas, or thiazolidinediones), be careful — gymnema can lower your blood sugar further, raising the risk of hypoglycemia. Also double-check any medications processed by your liver's CYP2C9 or CYP1A2 enzymes, as gymnema may affect their levels (moderate severity).

If you take trimethoprim (an antibiotic), thiamine levels may go up. No interactions are documented for benfotiamine in our data.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may appeal to you if you're looking for glucose support with vitamin B1 and want an herb-based approach — but the evidence for gymnema in particular is incomplete. If you take antidiabetes medications, blood pressure drugs, or have liver concerns, talk with your pharmacist before starting.

Gymnema extract6 drug types · 851 drugs

Antidiabetes Drugs

Theoretically, taking gymnema with antidiabetes drugs might increase the risk of hypoglycemia.
Gymnema reduces blood glucose levels in some human and animal research. In human studies, it has been shown to enhance the blood glucose lowering effects of hypoglycemic drugs. However, other research in adults with prediabetes or metabolic syndrome suggests that gymnema does not reduce fasting levels of blood glucose. Until more is known, monitor blood glucose levels closely.

Likelihood Probable Evidence B
Cytochrome P450 1A2 (Cyp1A2) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP1A2.
Animal and in vitro research shows that gymnema can inhibit the CYP1A2 enzyme. In one animal study, oral administration of gymnema for 7 days increased the plasma concentrations of phenacetin, a CYP1A2 substrate, by about 1.4-fold and reduced the clearance of phenacetin by about 29%.

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

Theoretically, gymnema might increase or decrease levels of drugs metabolized by CYP2C9.
Animal research shows that gymnema can induce the CYP2C9 enzyme. In one animal study, gymnema caused a 2.4-fold increase in the clearance of tolbutamide, a CYP2C9 substrate, in rats. In vitro research also shows that gymnema can inhibit CYP2C9.

Likelihood Possible Evidence D
Phenacetin

Theoretically, taking gymnema with phenacetin might increase the levels of phenacetin.
Animal research shows that gymnema, administered orally for 7 days, decreases the clearance of phenacetin in a dose-dependent manner by about 21% to 29% and increases plasma levels about 1.3- to 1.4-fold when compared to control.

Likelihood Possible Evidence D
Tolbutamide (Orinase)

Theoretically, taking gymnema with tolbutamide might the decrease levels of tolbutamide.
Animal research shows that gymnema, administered orally for 7 days, increases the clearance of tolbutamide by 2.4-fold when compared to control.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, gymnema might increase levels of drugs metabolized by CYP3A4.
One in vitro study using rat liver microsomes shows that gymnema can modestly inhibit the CYP3A4 enzyme. However, other in vitro research using human liver microsomes shows that gymnema does not affect CYP3A4 activity. Animal research also shows that gymnema does not alter the function of CYP3A4. In one study in rats, oral administration of gymnema for 7 days did not alter the clearance of amlodipine, a CYP3A4 substrate.

Likelihood Unlikely Evidence D

Thiamine HCl1 drug type · 3 drugs

Trimethoprim (Proloprim)

Trimethoprim might increase blood levels of thiamine.
In vitro, animal, and clinical research suggest that trimethoprim inhibits intestinal thiamine transporter ThTR-2, hepatic transporter OCT1, and renal transporters OCT2, MATE1, and MATE2, resulting in paradoxically increased thiamine plasma concentrations.

Advanced Glucose Support by OL Olympian Labs: Common Questions

Does Advanced Glucose Support by OL Olympian Labs interact with any medications?
Yes. Based on its ingredients, Advanced Glucose Support has a known interaction with 853 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Advanced Glucose Support 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.
Can I take this if I'm on metformin or another diabetes medication?
Not without talking to your doctor or pharmacist first. Gymnema in this product can lower blood sugar on its own, and combining it with antidiabetes drugs creates a moderate risk of your blood sugar dropping too low. Your provider may need to adjust your medication dose.
Is it safe to take while pregnant?
The data advises against gymnema during pregnancy due to insufficient safety information. Thiamine is actually needed in pregnancy, but only at doses your doctor recommends. Talk with your provider before taking this product.
What side effects should I watch for?
In studies, benfotiamine caused allergic skin reactions and mild stomach discomfort in a small number of people, at rates no higher than placebo. Rare but serious liver inflammation has been reported with gymnema. Stop and contact your doctor if you notice jaundice, unusual fatigue, or abdominal pain.
Does this product actually work for blood sugar control?
The evidence isn't clear. Thiamine is effective for thiamine deficiency, and benfotiamine may help with diabetic nerve damage. But the evidence for gymnema extract in particular for diabetes or prediabetes isn't established in our data — we don't have enough reliable research to say either way.
Can I take this with trimethoprim or other antibiotics?
Trimethoprim specifically may raise your thiamine levels, which is a minor interaction. If you take an antibiotic, mention this product to your pharmacist so they can check your other drugs against it.
