AI Insight
New research indicates that vitamin D2 supplements may reduce levels of vitamin D3 in the body, the more effective form that is naturally produced through sunlight exposure. This finding suggests that not all vitamin D supplements provide equal benefits, as vitamin D3 appears to be superior for raising overall vitamin D levels. Previous research has also indicated that vitamin D3 may offer stronger immune system support against pathogens compared to vitamin D2.
Why it matters
This research has important implications for public health recommendations and consumer choice in vitamin D supplementation. Individuals taking vitamin D2 supplements may need to reconsider their choice or consult healthcare providers about switching to vitamin D3 for more effective supplementation.
Understand the Science
Not all vitamin D supplements are created equal, and new research suggests that one popular form may have an unexpected downside. Scientists found that taking vitamin D2 can actually lower the body’s levels of vitamin D3, the form naturally produced by sunlight and more effective at boosting overall vitamin D. Previous studies also suggest that vitamin D3 may provide stronger immune protection against viruses and bacteria.
