    Most people of average height and weight need 5000 iu per day to reach a blood level of 50 ng/ml which is what we recommend here at the Vitamin D Council. Some people may need more than 5000 iu a day and the safe upper limit is 10,000 iu per day. (I will assume you have no major health issues or I might recommend taking more.)
