However, you need to check the plasma level first to adjust the dose and duration of supplementation. If the levels are normal you can supply up to 600 IU/day for adults and 400 IU/day for children. If there is insufficiency or deficiency you can go to up to 4000 IU/day for adults and 2000 IU/day for children.
