Dear Jacustomer,

The data suggests that after you stop take vitamin d it may take 2-3 weeks before vitamin d is out of your body because of prolonged half life.This also varies on various factors like time of consumption(duration),renal functions.The sun may help form vitamin d in your body but will not help remove vitamin d taken as oral dosage from your body to my opinion.
