Vitamin D supplementation positively affects activity but impairs stimulus response behavior in an age and sex specific manner in C57BL/6 mice

Several studies have begun to demonstrate the possible cognitive and physiological benefits of a fortified vitamin D diet. However, the behavioral effects of a high vitamin D fortified diet during adolescence has not been fully explored. In the present study, a 4-week vitamin D fortified diet (20,000 IU/Kg) compared to controls (1500 IU/Kg) was administered during the juvenile (4 weeks old) or early adult period (8 weeks old) in C57BL/6 J mice to investigate the effects of fortification on cognition, behavior, and their bone phenotype. After 4 weeks on the diet, vitamin D-treated and control groups underwent a 4-week battery of behavioral tests while remaining on their respective diets. We found that a fortified diet affected behavior in both an age- and sex-specific manner. When vitamin D was administered to juveniles, both sexes displayed impaired habituation to a loud tone. However, females also presented with impaired prepulse inhibition compared to female controls. In the adult treated group, the fortified diet increased only time spent in the open field and had no effect on anxiety-like behavior in the elevated plus maze. Juvenile mice treated with a high vitamin D fortified diet showed a decrease in the total volume compared to the control group in the proximal metaphysis and midshaft region of their femur. There were no differences in bone measurements for mice treated during adulthood. Overall, our results suggest that the juvenile period is a more sensitive time point to the startle response and bone effects of a diet supplemented with high vitamin D, while adults exhibited alterations in locomotive behavior.
