Children and adolescents with psychiatric illnesses who are treated with medications called second generation antipsychotic agents (SGA) often gain excessive weight during their treatment with these medications. This weight gain may result in the development of features of the metabolic syndrome or frank diabetes mellitus. There is no consensus on the best way to prevent these complications. The investigators' hypothesis is that daily vitamin D supplementation in these patients will result in decreased levels of the markers of metabolic syndrome with associated reduction in waist circumference.

||10 Years to 18 Years
|Genders Eligible for Study:
|Accepts Healthy Volunteers:
- Males/females between the ages 10 through 18 years,

- Subjects with acquired or congenital disorders of vitamin D metabolism,
- Subjects on calcium and vitamin D replacement therapy, such as calcium carbonate, or ergocalciferol, or cholecalciferol,
- Subjects taking any weight loss medications, such as orlistat, and sibutramine,
- Subjects on medications that might affect glucose levels, such as insulin or metformin.
