Overweight children are typically lacking in vitamin D. However, a basic dose of vitamin D in the 400 IU to 600 IU range cannot correct their deficiency. Research conducted at the University of Missouri has shown that 4000 IU of vitamin D per day in overweight adolescents is safe and effective at actually raising their vitamin D level.

Optimizing vitamin D in overweight children can help unravel the problem, along with a better diet and exercise. While vitamin D is not a one-shot obesity remedy, it is important to the health of white adipose tissue. Having adequate vitamin D is important for healthy immune function and normal histamine response.
