Benfotiamine

Benfotiamine is a Vitamin supplement available in 1 form.

Not all forms of Benfotiamine are equal. The form you choose determines how much Benfotiamine actually reaches your tissues, and the difference between the best and worst forms can be substantial. Benfotiamine is the fat-soluble, S-acyl derivative of thiamine (vitamin B1) with significantly greater bioavailability than water-soluble thiamine forms, achieving higher intracellular concentrations in tissues. Research suggests it supports healthy glucose metabolism, nerve function, and advanced glycation end-product defense more effectively than standard thiamine.

Benfotiamine Preferred (Preferred Form) has a bioavailability rating of high absorption.

Benfotiamine is a fat-soluble form of vitamin B1 (thiamine) with 5x greater bioavailability than water-soluble thiamine HCl. Research demonstrates its ability to activate transketolase and redirect glucose metabolism away from harmful AGE-forming pathways. Multiple clinical studies support its use for nerve health and metabolic support.

Benfotiamine achieved significantly higher plasma thiamine concentrations and tissue uptake compared to water-soluble thiamin mononitrate at equivalent oral doses in healthy male volunteers. PMID: 1776825

In a crossover study of 7 volunteers, benfotiamine demonstrated the highest thiamine bioavailability among three preparations, with the most rapid absorption and greatest erythrocyte transketolase activity. PMID: 9587048

Randomized crossover PK studies in healthy volunteers (n=24 per group) assessing lipophilic thiamine derivatives. Benfotiamine was an arm in study A, where it was bioequivalent to fursultiamine (90% CI within conventional bioequivalence range). Authors concluded lipophilic thiamine derivatives show clear benefits for thiamine absorption. PMID: 27707509

Benfotiamine is classified as Preferred Form by FormulaForge — our top recommendation for Benfotiamine. It carries a bioavailability rating of high absorption, meaning more of the active compound reaches your tissues per dose unit compared to lower-rated forms.

When choosing a Benfotiamine supplement, read the label for the specific form name — that is what determines how much you actually absorb. Preferred Forms have the strongest research-backed evidence for efficient absorption.

Other forms may be appropriate depending on individual goals, cost considerations, and your healthcare provider’s guidance. The best form for you depends on your specific health needs.

Individual dose requirements vary based on health goals, body weight, and existing nutrient intake. Your healthcare provider can help you determine an appropriate amount of Benfotiamine for you.

Side Effects: Consult your healthcare provider regarding tolerability, particularly at higher doses.
