Benfotiamine is a synthetic, fat-soluble derivative of thiamine with improved tissue uptake and bioavailability compared with water-soluble thiamine HCl.

There are potential interactions, especially with diabetes medications; discuss with your provider to adjust glucose-lowering therapy if necessary.

Short- and medium-term studies show good tolerability, but long-term use should be supervised by a healthcare professional and monitored for benefits and side effects.
