HelloPharmacist Scorecard of Benfotiamine 150 mg by Doctor's Best
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 2 active ingredients: benfotiamine (a fat-soluble form of the B vitamin thiamine) and L-leucine (an amino acid). Benfotiamine is designed to be absorbed better than regular thiamine, which is why it's used in formulas targeting nerve and kidney health in people with diabetes.
The product also contains inactive ingredients — hypromellose, microcrystalline cellulose, and silicon dioxide — which are typical capsule fillers and binders.
Does it work?
Moderate evidence
Benfotiamine is possibly effective for diabetic nerve pain (diabetic neuropathy). For diabetic kidney damage (diabetic nephropathy), the evidence leans toward it being possibly ineffective.
The data on benfotiamine for alcohol-related nerve damage, Alzheimer disease, and general peripheral nerve pain is too sparse to rate — we simply don't have enough reliable evidence yet.
How safe is it?
Well-documented data
Benfotiamine is generally well tolerated in studies, though long-term safety hasn't been fully worked out. In one clinical trial, a small number of participants reported mild allergic skin reactions or slight stomach discomfort, but rates were similar to placebo.
The facts note there isn't enough safety information to recommend it during pregnancy, so talk with your doctor before taking it if you're pregnant. Safety while breastfeeding hasn't been well studied either, so caution is advised.
Meds to double-check
No known interactions
No interactions are documented in our data for the benfotiamine in this product. L-Leucine couldn't be checked, so use the search tool on this page with your exact medications to be thorough.
The bottom line
Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. No medication interactions are currently documented, and safety information is well characterized.
If you have diabetic nerve pain and want to explore benfotiamine, the evidence suggests it may help — but it's worth a conversation with your doctor or pharmacist first. If you're pregnant, breastfeeding, or taking any medications, check in before starting.
