Vitamin B12

Vitamin B12, or cobalamin, fuels some of the body’s most essential processes, including DNA synthesis, red blood cell production, and nervous system regulation.


Its production is based on a complex fermentation process that was developed by EUROAPI as early as 1966.


As the pharmaceutical industry’s sole Western manufacturer of vitamin B12, EUROAPI plays a crucial role in ensuring its global supply.
