HelloPharmacist Scorecard of Benfotiamine-V 150 mg by Benfotiamine.Net, Inc.
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
Partial disclosure
Benfotiamine-V contains 2 active ingredients: thiamine, benfotiamine, and S-benzoylithiamine-O-monophosphate — all forms of thiamine (vitamin B1) designed to support nerve health. The product also contains inactive ingredients (microcrystalline cellulose, stearic acid, and hydroxypropyl methylcellulose), which are fillers and binders that help form and stabilize the capsule.
Does it work?
Moderate evidence
Benfotiamine is possibly effective for diabetic neuropathy (nerve damage from diabetes). It's rated possibly ineffective for diabetic nephropathy (kidney damage from diabetes).
For alcohol use disorder, Alzheimer disease, and peripheral neuropathy (nerve damage in the limbs), the evidence isn't established enough to rate it one way or the other. The data on S-benzoylithiamine-O-monophosphate shows the same effectiveness profile.
How safe is it?
Well-documented data
Both benfotiamine and S-benzoylithiamine-O-monophosphate are generally well tolerated in studies, but long-term safety hasn't been fully studied. In a clinical trial of patients taking 300–600 mg daily for 6 weeks, a small number reported allergic skin reactions and slight stomach discomfort — rates no different from placebo.
There isn't enough safety information to use this product during pregnancy unless your doctor advises it. Safety while breastfeeding hasn't been well studied, so caution is advised; talk with your doctor or pharmacist.
Meds to double-check
No known interactions
No interactions are documented in our data for the ingredients we could check. Still, talk with your doctor or pharmacist about your specific medications before you start.
The bottom line
Scorecard at a glancePartially disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
Benfotiamine-V may be worth considering if you have diabetic nerve damage and want to try a possibly effective option. If you're pregnant, breastfeeding, or have long-term safety concerns, check with your doctor or pharmacist first.
No interactions are documented for the ingredients we could verify, but bring your full medication list to your pharmacist to be sure.

Thiamine
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.
