Purpose of reviewVitamin D is important in maintaining calcium homeostasis, but its role in kidney stone disease and its effect on stone formation are still not clear.Recent findingsKidney stone formers tend to experience enhanced intestinal calcium absorption, increased urinary calcium excretion, and excessive bone mineral loss. Although direct actions of active vitamin D have been implicated in all these processes, the effect of nutritional vitamin D (vitamin D-2 or vitamin D-3) use on calcium balance among stone formers is still not clear. In addition, the safety of nutritional vitamin D use in the stone forming population is also not established, considering the potential effect of its use on raising urinary calcium. However, most of the observational studies do not support a significant association between higher nutritional vitamin D store and increased risk of stone formation. Short-term nutritional vitamin D repletion in stone formers with vitamin D deficiency also does not appear to increase urinary calcium excretion.SummaryThe effect of nutritional vitamin D use in stone formers is still not clear. As vitamin D deficiency is highly prevalent among stone formers, future prospective studies are needed to establish the biological effect, as well as the safety and efficacy of nutritional vitamin D therapy in this unique patient population.
