Tag: Vitamin b12 color

The distinctive deep red color of many vitamin B12 injections and supplements often prompts a common question: **Is vitamin B12 always red?** While pure forms of the vitamin are undeniably vibrant, the answer is more nuanced, depending on the specific form of B12 and its concentration. The color is not a dye but a natural result of its unique molecular structure, which centers around a single cobalt atom.

Vitamin B12 is a large and complex molecule containing a single cobalt atom, which is the source of its characteristic ruby-red color. This scientific fact means that the vibrant red you see in B12 products often has nothing to do with added artificial red dye.
