Cyanocobalamin is a synthetic form of vitamin B12, which is also known as cobalamin.
Cyanocobalamin is often used in supplements and protein powders as a source of vitamin B12, particularly in vegetarian and vegan products that do not contain animal-derived ingredients. Like other forms of vitamin B12, cyanocobalamin is important for the formation of red blood cells and DNA, as well as for the proper functioning of the nervous system.
Cyanocobalamin is generally considered safe when used in recommended amounts.
