Vitamin B₁₂ has, among other functions, that of generating red blood cells. The lack of these globules generates anemia. This vitamin contains cobalt which gives it red color and it is also called "cobalamin".

Industrially it appears in the form of a red powder.

Present in the human body, with advanced age, cobalamin thins out and can leave room for oxidative phenomena due to its lack (1).

This vitamin, soluble in water, has a rather complex relationship with the skin (2).

Other important functions are those concerning the digestive system, in particular, the intestine (3), bone health (4) and the nervous system (5).
