B-vitamin improves depressive symptoms

Vitamin B12 and other B-vitamins play a role in producing brain chemicals that affect mood and other brain functions. Recent evidence suggests a link between the nervous system and the immune system, and that the immune system plays a significant role in depression.

Doctors reviewed studies from 2008 through 2016 on B-vitamins, immune system, inflammation, and the links between these and depression. Overall, there is a clear link between B-vitamins, the immune system, and depression. Low levels of vitamins B1, 2, 3, 6, 9, and 12 are common in depression. One of the major findings: B-vitamin supplementation reduced depressive symptoms.

Doctors also discovered a link between pro-inflammatory profiles and depression, and that anti-inflammatory nutrients improve depression outcomes. Discussing the findings, doctors said, “It is clear that deficiency in B-vitamins results in symptoms of depression that affect the health and well-being of individuals.”
