Link Found Between Childhood OCD and Certain Nutrients

A recent suggests that there may be a link between childhood obsessive-compulsive disorder (OCD) and blood levels of vitamin D, vitamin B12, and homocysteine.


Participants in the study included 52 children and adolescents who were diagnosed with OCD, as well as 30 healthy controls. The researchers tested all of the participants for vitamin B12, homocysteine, and vitamin D levels. They also collected sociodemographic information and measured mental illness symptoms with the state-trait anxiety inventory 1 and 2, Kovacs Depression Inventory, and the Yale-Brown Obsessive Compulsive Scale.


After examining the data, the researchers determined that the children with OCD had higher scores on the anxiety and depression scales. They also had lower levels of vitamin B12 and higher levels in homocysteine. Additionally, they found that the OCD patients had lower levels of vitamin D and that vitamin D status had a negative correlation with disease severity.


Researchers from Ordu University in Turkey conducted the study. It was published online ahead of print on April 20, 2017, in Psychiatry Research.


Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun.


Vitamin B12 is a water-soluble vitamin that is essential to the proper function of the brain, nervous system and formation of blood. Deficiencies in vitamin B12 can lead to fatigue, depression and memory lapses. Food sources of vitamin B12 include liver, turkey giblets, oysters, clams, king crab and whole milk.
