“Vitamin K helps vitamin D absorption for bone health.”
The evidence does not show that vitamin K helps the body absorb vitamin D. What reliable sources do support is that vitamins D and K can work together in bone health through different roles: vitamin D helps regulate calcium and induces certain proteins, while vitamin K activates some of those proteins. That makes the claim directionally related to a real interaction, but wrong in its stated mechanism.
“Vitamin D deficiency is widely overdiagnosed in clinical practice.”
Strong evidence shows vitamin D testing is widely overused — with studies finding 57–77% of tests lack clinical justification — but the claim conflates overtesting with overdiagnosis. Overtesting means ordering tests without guideline indications; overdiagnosis means incorrectly labeling healthy people as deficient. While contested diagnostic thresholds may inflate deficiency labels in some populations, global data also show substantial true deficiency prevalence with meaningful health associations. The unqualified assertion that deficiency is "widely overdiagnosed" overstates what the clinical literature supports.
