First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how taking vitamin D3 and K2 supplements for 90 days changes blood levels and the community of bacteria in the gut (the microbiome) in healthcare workers with low vitamin D. About 96 participants will take either a vitamin D3, K2, both, or a placebo pill. Researchers will measure inflammation markers and gut bacteria before and after supplementation to understand how these vitamins work together.
