Experts said, that a bad mood and even some psychiatric symptoms can be evidence of vitamin deficiency in the body. In particular, we are talking about B vitamins.

It turned out that vitamin B12 plays a role in the biochemical balance of the brain and affects the processes responsible for mood and a number of other functions. For example, low B12 levels can be associated with depression.

What's more, B12 deficiency can cause almost any psychiatric symptom, from anxiety and panic to depression and hallucinations.

A study published in the US National Library of Medicine says that depressed patients who participated in the study were found to have both low levels of folate and low levels of vitamin B12.
