How do I get Vitamin D from the sun?
<|assistant|>
Vitamin D is synthesized in the skin by a reaction to UVB rays from the sun. The amount of Vitamin D produced is dependent on the intensity of the UVB rays, the duration of exposure, and the time of day. Vitamin D levels typically peak within 30 minutes of sun exposure.
