Vitamin B12 and mental health

Vitamin B12 is a key component in the formation of red blood cells.

Its deficiency could lead to an oxygen-transport problem in the blood known as pernicious anemia. This disorder may cause issues like mood swings, paranoia, irritability, confusion, dementia, and hallucinations (or mania).

A diet that includes vitamin B complex helps boost mental health.

Vitamin B deficiency could negatively influence your memory function, and cause cognitive impairment and dementia.
