HelloPharmacist Scorecard of Benfotiamine 300 mg Maximum Strength by Swanson
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: benfotiamine, a fat-soluble form of thiamine (vitamin B1). Each capsule delivers 300 mg.
The remaining ingredients — rice flour, hypromellose, magnesium stearate, and silica — are inactive excipients that make up the capsule and help with manufacturing.
Does it work?
Moderate evidence
Benfotiamine is possibly effective for diabetic neuropathy (nerve pain from diabetes). For diabetic kidney disease (nephropathy), the evidence suggests it's likely ineffective.
For alcohol use disorder, Alzheimer disease, and general peripheral neuropathy, we don't have enough reliable evidence to know whether it works. If you're considering it for one of these conditions, talk it over with your doctor about what the current research shows for your specific situation.
How safe is it?
Well-documented data
Benfotiamine is generally well tolerated in the studies we have, but long-term safety hasn't been fully studied. In one trial of 98 people taking 300–600 mg daily for 6 weeks, a small number reported allergic skin reactions and mild stomach discomfort — but these rates didn't differ from placebo.
There isn't enough safety data during pregnancy, and safety while breastfeeding hasn't been well studied, so talk with your doctor or pharmacist before using this product if you're pregnant, planning to become pregnant, or breastfeeding.
Meds to double-check
No known interactions
No interactions are documented in our data for benfotiamine. That said, run your specific medications through the search tool on this page, and let your doctor or pharmacist know you're taking this product.
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.
Benfotiamine may be worth considering if you have diabetic nerve pain and your doctor thinks it's a fit for you. If you're pregnant, breastfeeding, or planning to become pregnant, check with your doctor or pharmacist first — the safety data isn't solid enough yet.
Long-term use hasn't been well studied, so have that conversation with your healthcare provider too.
