If you want to: But it does not seem necessary to me take about 1000 iu of vit d 3 per 25 # of body wt per day ( ie so a 100 # person would take ~ 4000 iu /day) have your primary care doctor order a vit d level on you after ~ 3-5 months to see that you are getting enough you want a vit level >50 and.
