Many cases of vitamin B12 deficiency are overlooked or misdiagnosed1, according to a study published in the Mayo Clinic Proceedings. This is often due to misconceptions, like vitamin B12 deficiency can only occur in conjunction with anemia or that it only affects the elderly.

Vitamin B12 plays a major role in preventing a type of anemia called megaloblastic anemia2, characterized by oversize red blood cells and a lack of folate or B12. The condition commonly leads to symptoms, like tiredness and weakness. 

Additionally, "Deficiencies in cobalamin (vitamin B12)3 can result in diminished energy and exercise tolerance, together with fatigue and shortness of breath," one study states. 

Studies have linked vitamin B12 deficiencies with cognitive impairment4, including things like brain fog, lack of concentration, poor memory, and even a greater risk of developing Alzheimer's disease. "People with higher levels of vitamin B12 seem to have less brain shrinkage as they get older," psychologist Elizabeth Lombardo, Ph.D., P.T., previously told mbg. "Taking vitamin B12 when you are deficient can be helpful to address memory, mental clarity, overall energy, and depressed mood."
