Anorexia, Vitamins, and Executive Dysfunction: Relationships in Daily-Life Experiences of Behavioral Regulation Difficulties.

The present study employed an online survey to examine associations between anorexia nervosa, vitamin supplementation, and executive function deficits. Anorexic status positively correlated with both inhibitory control and set-shifting deficits. Vitamin supplementation negatively correlated with inhibitory control deficits, and an interaction effect of anorexic status and multivitamin supplementation was found.
