Vitamin B12 Helps the Nervous System to Function Properly
Vitamin B12 is essential for normal cognitive functioning; it is a crucial vitamin for metabolism in the body and the production of something called S-adenosyl methionine (SAM). S-adenosyl methionine is needed for neurological function, for mood regulation, and for coping with stress. When vitamin B12 is lacking, it is not uncommon for a person to begin to experience depression, anxiety, and unexplainable mood swings. [9]
