What Is Benfotiamine?

Benfotiamine benefits are strongest for people at risk of thiamin deficiency or those with increased vitamin B1 needs, such as:

  • People eating highly processed diets
  • Regular alcohol drinkers
  • Individuals taking diuretics, cardiac glycosides, or hydantoin derivatives
  • People with diabetes or diabetic neuropathy
  • Older adults with memory decline
  • Anyone showing early deficiency symptoms (fatigue, irritability, poor appetite)

Additional Health Benefits of Benfotiamine

  • Better Sleep – May help those who wake during the night and struggle to fall back asleep.
  • Mood Support – May ease anxiety or mild depression.
  • Diabetes Support – Works especially well when combined with alpha-lipoic acid, helping protect nerves and regulate blood sugar.

Benfotiamine Dosage Guide

  • Typical range: 150–600 mg per day, divided into two doses.
  • For nerve pain or severe deficiency: doses up to 1,000 mg daily may be used under medical supervision.

Possible Benfotiamine Side Effects

Benfotiamine is safe for most people, though mild side effects (stomach upset, rash, dizziness) can occur.
⚠️ Caution: Those with kidney disease or women who are pregnant/breastfeeding should consult a provider before use.
