Vitamin B12: Supporting Blood and Nervous System Function

Vitamin B12 is involved in normal red blood cell formation and neurological function. It is an important nutrient for maintaining adequate nutrition throughout adulthood.

Vitamin B12 occurs naturally mainly in animal-derived foods. People following a strict vegan diet may need fortified foods or supplementation because unfortified plant foods do not generally provide naturally occurring vitamin B12.

Food Sources of Vitamin B12

Sources include:

  • Milk and dairy products
  • Eggs
  • Fish
  • Meat
  • Poultry
  • Fortified foods

Older adults and people with certain medical conditions or medication-related absorption issues may require individual dietary guidance.

If you follow a vegetarian or vegan dietary pattern, discuss your vitamin B12 needs with a healthcare professional or qualified dietitian.
