The induction of the catabolism of 1,25-dihydroxyvitamin d by these drugs is thought to contribute to their deleterious side effects. This level is often considered as reflecting long-term individual vitamin d status. According to some studies, vitamin d3, which is produced by the skin, is more powerful, hence more effective at raising blood levels compared with vitamin d2, however, some studies say they are equal.

Vitamin d supplementation of canadian infants: Practices of montreal mothers. Although this strategy can be a useful methodology to force a physiologic change (And, thus, to possibly piece together a mechanism of action), these studies offered little information for lower doses, which are more realistic in terms of what individuals are likely to be able to consume within their daily diet and gain from sunlight exposure and the concentrations of ergocalciferol and cholecalciferol available in commercial supplements. In contrast, holick et al Recently demonstrated that vitamin d 2 and vitamin d 3 were equally efficacious in raising 25-ohd concentrations when given as a daily 1,000-iu dose. Scientific opinion on the tolerable upper intake level of vitamin d. Conclusions: This meta-analysis indicates that vitamin d 3 is more efficacious at raising serum 25(Oh)d concentrations than is vitamin d 2, and thus vitamin d 3 could potentially become the preferred choice for supplementation. The interventions used for all studies were vitamins d 2 and d 3 of varying dosages and treatment time periods.

Inverse associations were found between increases in 25-hydroxyvitamin d levels and the baseline serum 25-hydroxyvitamin d levels or the concomitant intake of calcium supplements, but these associations were not statistically significant. For addressing the dose-response issue and for ascertaining the clinical significance of changes in 25-hydroxyvitamin d level obtained in the whi trial, we made a systematic review of changes in circulating 25-hydroxyvitamin d level reported by randomized trials that tested supplementation with vitamin d in mainly caucasian subjects over 50 yr old. A fourth source of variability was probably the different laboratory tests used for measuring serum 25-hydroxyvitamin d concentrations. Recommended daily vitamin d supplementation for adults.
