HelloPharmacist Scorecard of G-150 Benfotiamine 150 mg by BenfoComplete.com

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.

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 1 of its 1 active ingredient.
  • “Benfotiamine” is listed as a grouped ingredient — the label gives one combined amount (150 mg) without saying how much of each component you get.

This product contains one active ingredient: thiamine (also called vitamin B1), provided as benfotiamine, a fat-soluble form designed for better absorption. Thiamine is an essential B vitamin your body needs to convert food into energy and support nerve function.

The capsule also contains inactive ingredients — gelatin, microcrystalline cellulose, magnesium stearate, and water — that help form and stabilize the supplement.

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: Diabetic support, heart health, energy, nerve health.
  • We looked for evidence on: Diabetes, Diabetic neuropathy, Diabetic nephropathy, Cardiovascular disease (CVD), Heart failure, Dyslipidemia — and 4 related terms.
  • The strongest evidence on file: Thiamine is rated "Effective" for Thiamine deficiency (Natural Medicines).
  • Also on file: Thiamine is rated "Effective" for Wernicke-Korsakoff syndrome (WKS).
  • Also on file: Thiamine is rated "Possibly Ineffective" for Heart failure.

Thiamine is effective for treating thiamine deficiency and Wernicke-Korsakoff syndrome (a serious neurological condition from severe thiamine lack). It's possibly effective for dysmenorrhea (menstrual cramps).

Evidence doesn't support its use as a mosquito repellent or for heart failure.

The evidence, ingredient by ingredient Benfotiamine 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 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.

Thiamine is generally very safe when taken by mouth at normal doses. Allergic reactions like skin inflammation are rare; even rarer are severe reactions if given by injection.

Thiamine is essential during pregnancy and breastfeeding — your body needs it for your baby's development and milk production — but use it only at the amounts your doctor or midwife recommends rather than self-dosing high-dose supplements.

Side effects, ingredient by ingredient Benfotiamine Thiamine

Meds to double-check

Minor interactions only
Known Interaction Concern · database check
Minor only

Only Minor-severity interactions are documented for these ingredients.

Why this rating?
  • 1 of the 1 matched ingredient can interact with medications — Thiamine.
  • The most serious interaction on file is rated Minor.
  • For scale: 3 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 trimethoprim (Proloprim), check with your pharmacist before adding this product — it may raise your thiamine levels slightly. No other medication interactions are documented for the ingredients we could check.

The bottom line

Scorecard at a glanceFully disclosed formula with clinical evidence supporting its stated purpose. Only minor medication interactions are documented, and safety information is well characterized.

G-150 Benfotiamine is appropriate if you're treating a thiamine deficiency or Wernicke-Korsakoff syndrome. If you take trimethoprim (Proloprim), there's a minor interaction, but it's unlikely to be harmful.

Talk with your pharmacist before starting, especially if you're pregnant, breastfeeding, or on any antibiotics.

How can one product interact with so many drugs?
G-150 Benfotiamine 150 mg 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.
Is benfotiamine better than regular thiamine?
Benfotiamine is a fat-soluble form of thiamine designed to absorb better in the body. The facts we have focus on thiamine's effects; we don't have a direct comparison between the two forms on file.
Can I take this if I'm pregnant or breastfeeding?
Yes — thiamine is actually essential during pregnancy and breastfeeding for your baby's development and your milk. Use only the amounts your doctor or midwife recommends, not high-dose supplements on your own.

Thiamine is possibly effective for dysmenorrhea (menstrual cramps), but the evidence isn't strong. Talk to your doctor about whether it's worth trying for your situation.
What side effects might I get?
Thiamine taken by mouth is very safe; allergic reactions like skin rashes are rare. If you were to get an injection (which this product isn't), severe allergic reactions are also uncommon but possible.
Can this help with heart failure?
No — thiamine is possibly ineffective for heart failure. If you have heart failure, work with your cardiologist on proven treatments rather than relying on this supplement.
