What it is

Cyanocobalamin is a form of vitamin B12. It is typically made through bacterial fermentation. This synthetic form of vitamin B12 is added to foods and supplements.

Why it's used

Manufacturers add cyanocobalamin to foods to fortify them with vitamin B12. It is commonly found in fortified cereals, plant-based milk alternatives, and nutritional supplements.

Health notes

In the US, cyanocobalamin is generally recognized as safe (GRAS) by the FDA when used as a nutrient. Vitamin B12 is essential for nerve function and the formation of red blood cells. JECFA and EFSA have evaluated vitamin B12 and established acceptable daily intakes. High doses are generally well-tolerated, as excess vitamin B12 is excreted by the body.

Allergen info

Not a major allergen. It is not derived from any of the nine FDA major allergens, nor does it contain gluten.
