According to scientific research, aqueous solutions of cyanocobalamin, a common form of B12, are known to be sensitive to light. The answer to whether vitamin B12 has to be protected from light is a definitive yes, as exposure can significantly degrade its potency and stability. This is especially critical for liquid formulations and injectable forms of the vitamin, where photodegradation occurs more rapidly.
