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
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
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.
How safe is it?
Well-documented data
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.
Meds to double-check
Minor interactions only
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.

G-150 Benfotiamine 150 mg by BenfoComplete.com Drug Interactions
HelloPharmacist Interaction Report
G-150 Benfotiamine 150 mg from BenfoComplete.com contains thiamine, which has a minor interaction with one antibiotic.
Read the full breakdown — every affected drug type, severity by severity
Trimethoprim (Proloprim), an antibiotic used to treat certain infections, may raise thiamine blood levels. This happens because trimethoprim blocks transporters in your gut, liver, and kidneys that normally move thiamine around your body — so more of it stays in your bloodstream.
This is a minor interaction and unlikely to cause a problem, but it's worth knowing if you take this antibiotic regularly.
No other medication interactions are documented for the thiamine in this product. Check your exact medications with the search tool on this page to be sure.
