What does it do?

Cyanocobalamin is a synthetic vitamin belonging to the vitamin B12 group. It is primarily used to improve anemia and neurological symptoms caused by vitamin B12 deficiency. It is also included in multivitamins and mineral supplements to serve as a nutritional supplement.

This ingredient plays an essential role in the production of red blood cells and the maintenance of nerve function in the body. When vitamin B12 is deficient, red blood cells are not produced properly, leading to anemia, and cyanocobalamin supplements this to aid in normal blood production and nerve cell function.
