A British group reported recently that administration of vitamin D2, which is converted to vitamin D3 by the body, may be disadvantageous. A review of random controlled trials showed that taking vitamin D2 can lead to a decrease in vitamin D3 levels, the more active form generated by sunlight exposure. The research indicates that D2 supplementation may not only be less effective, but can also lead to lower concentrations of D3 in the circulation. [Emily I G Brown, et al. Effect of Vitamin D2 Supplementation on 25-Hydroxyvitamin D3 Status: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. Nutr Rev, 2025 Sep 18:nuaf166.doi: 10.1093/nutrit/nuaf166]. Is this an accurate and meaningful assessment? What is most important for us to know?
