Benfotiamine is a synthetic S-acyl derivative of vitamin B1 (thiamine) with neuroprotective effects. By increasing vitamin B1 levels, benfotiamine can increase energy, mood and alertness.

Scientific Name:
S-Benzoylthiamine O-monophosphate


  • After ingestion, benfotiamine is converted into vitamin B1 (thiamine)[1]
  • This synthetic S-acyl derivative of thiamine has a 5-fold higher bioavailability[1]
  • Thiamine increases the production of ATP by enhancing carbohydrate metabolism[2]
  • Thiamine increases mood, energy, and alertness[2]
  • Useful for the treatment of neuropathies and chronic pain[3]
  • Can increase the activity of transketolase – reduces vascular damage associated with neuropathy and retinopathy[4]
  • Antioxidant action via NADPH oxidase[5]
  • Decreases the levels of advanced glycation end products (AGEs) – substances that contribute to neurodegeneration[6]
