The Claim
In human primary myoblasts, 1,25-dihydroxyvitamin D3 induces a dose-dependent increase in CYP24A1 mRNA expression, with 1 nmol/L causing an 8,634-fold increase compared to baseline, confirming functional vitamin D signaling in human muscle cells.
What the research says
Not yet evaluated
We are still looking at what the research says.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When scientists add a form of vitamin D to human muscle cells in a lab, the cells start making a lot more of a specific molecule—like turning up a volume knob—showing that these muscle cells can respond to vitamin D.
