Overview

Alcohol depletes B1, B6, folate — repletion supports neurological recovery.

Natural sources
  • Whole-food sources (animal products for fat-soluble and B-complex vitamins; produce for water-soluble vitamins)
  • Fortified foods (cereals, dairy, plant milks, nutritional yeast)
  • Multivitamins or stand-alone supplements in synthetic or food-derived form
Common forms
  • Capsule or softgel
  • Sublingual tablet or liquid
  • Methylated active form for sensitive individuals
  • Multivitamin matrix

Mechanism of action

Alcohol blocks thiamine absorption and accelerates B6/folate excretion; replacing them prevents Wernicke's and improves recovery.

Pathways
  • · Alcohol blocks thiamine absorption
  • · accelerates B6/folate excretion
  • · replacing them prevents Wernicke's
  • · improves recovery
