No change in calcium absorption in adult Pakistani population before and after vitamin D administration using strontium as surrogate

Khan AH et al. – A single vitamin D3 injection of 600,000 IU significantly increase mean 25OHD concentration and tended to lower iPTH concentrations in volunteers with initially low 25OHD status, suggesting to utilize this simple form of treatment to improve vitamin D status and to have a possible biological effect on Ca homeostasis. However, the authors found no obvious effect on Sr absorption, suggesting the possibility that maximal vitamin D–dependent Ca absorption had already been achieved in these volunteers at a lower vitamin D status.
