Benfotiamine is a synthetic form of vitamin B1 used to raise thiamine levels, especially for diabetic nerve health.
When people search for what is benfotiamine supplement, they are usually looking for a more absorbable version of vitamin B1. Standard thiamine (vitamin B1) is water‑soluble and not absorbed perfectly, but benfotiamine is fat‑soluble, allowing it to enter cells more easily.
Benfotiamine: A Bioavailable Form of Vitamin B1
Benfotiamine is a lab‑made derivative of thiamine, sometimes called S‑benzoylthiamine O‑monophosphate. It was developed to overcome the limited absorption of ordinary B1. Once in the body, it is converted to thiamine and can reach higher blood levels than an equivalent dose of standard thiamine. Because it is fat‑soluble, it also may penetrate nerve tissues more effectively—this is why it is studied for diabetic neuropathy.
Benfotiamine Supplement Uses: What the Evidence Shows
The strongest evidence for benfotiamine is in diabetic peripheral neuropathy. A 2023 review in Nutrients confirms these findings and notes the supplement’s good safety profile. However, the Alzheimer’s Drug Discovery Foundation notes that cognitive studies have been small and inconclusive, so it is not recommended for memory issues at this time. For kidney damage in diabetes, benfotiamine does not appear to improve markers. Research is insufficient for other conditions like arthritis or alcohol‑related nerve damage.

Benfotiamine Safety and Dosage
Benfotiamine is likely safe when taken by mouth at 150–600 mg daily for up to 24 weeks. Most trials report only mild gastrointestinal upset or skin rashes. Long‑term safety beyond six months hasn’t been well studied. Because it’s an over‑the‑counter supplement in the United States, quality varies—choose a reputable brand. Always consult a healthcare provider before starting any new supplement, especially if you take medications.
FAQs
Is benfotiamine the same as vitamin B1?
No. Benfotiamine is a synthetic derivative of thiamine (vitamin B1). The body converts it to thiamine, but it is not a natural form of the vitamin. It acts as a prodrug that delivers more thiamine than an equivalent amount of standard B1.
How much benfotiamine should I take for neuropathy?
Most clinical studies use 150–600 mg per day, often divided into two or three doses. Start at the lower end and consult your doctor, especially if you have kidney issues or take other medications.
Are there any side effects of benfotiamine?
Side effects are rare but can include mild stomach upset or skin rash. Most trials report only these minor issues. Long‑term safety data beyond six months is lacking, so stay within the studied dose range and duration.
