Excessive vitamin B12 concentrations are more common than deficiency in patients with anorexia nervosa: a cross-sectional study
This study demonstrated that excessive vitamin B<sub>12</sub> concentrations are more prevalent than deficiency in patients with AN, suggesting that the routine administration of vitamin B<sub>12</sub> to patients with AN should be reconsidered. Elevated vitamin B<sub>12</sub> concentrations might be associated with starvation-induced autophagy in the liver. Its potential role in physical complications warrants further investigation.
