1 min read


Some studies have shown positive effects on patients with depression when supplementation of Vitamin B12 is implemented.

“Deficiency of Vitamin B12 can result in haematological changes, neurological and psychiatric problems, which can manifest as irritability, changes in personality, depression, and memory loss.

“It is also known to worsen depression by excitotoxic reactions caused by the accumulation of homocysteine.”

It concluded: “Based on the reviewed studies, it was found that although there is no concrete evidence showing positive effects of Vitamin B12 on depression or depressive symptoms, the lower levels of vitamin B12 in the body are associated with a higher risk of developing depression.”
