Source of validity: Scientific
Rating (out of 5): 5

Vitamin B12, also known as cobalamin, is scientifically validated as essential for the health of the nervous system. It plays a crucial role in the formation of myelin, the protective sheath around nerves, and in the synthesis of neurotransmitters. Deficiency of vitamin B12 is well-documented to cause neurological and psychiatric symptoms, including numbness, tingling, memory loss, mood changes, and, in severe cases, irreversible nerve damage. Numerous clinical studies and medical guidelines recognize that B12 supplementation can prevent or reverse neurological symptoms caused by deficiency. For example, the National Institutes of Health (NIH) and clinical practice guidelines from neurology organizations emphasize vitamin B12’s role in supporting nerve health and recommend supplementation in cases of deficiency. B12 deficiency is particularly common among older adults, vegetarians, individuals with absorption disorders, and those taking certain medications. There is strong consensus in the medical community regarding the necessity of adequate B12 for nervous system maintenance, making its use for this purpose firmly supported by scientific evidence.
