Cyanocobalamin is a synthetic form of vitamin B12, a nutrient responsible for various bodily functions, including red blood cell formation and neurological health. In the context of food additives, cyanocobalamin is often used to fortify and supplement food products with vitamin B12. The production of cyanocobalamin involves a chemical synthesis process, typically starting with certain bacterial strains that naturally produce B12 through fermentation. Cyanocobalamin can be added to a variety of foods, such as cereals, plant-based alternatives, and nutritional supplements, to address dietary deficiencies.
