The Claim
In older, mobility-limited women with vitamin D insufficiency, the increase in intramyonuclear vitamin D receptor concentration is strongly correlated with the rise in serum 25-hydroxyvitamin D levels, independent of treatment group, suggesting a direct biological link between vitamin D status and muscle receptor expression.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
When older women who have trouble moving around get more vitamin D in their blood, their muscle cells seem to respond by making more vitamin D receptors — and this happens no matter how they got the vitamin D, like from pills or sun exposure.

What the research says
1 studyThe study gave older women vitamin D pills and found that when their blood vitamin D levels went up, so did the number of vitamin D receptors in their muscle cells — even if they didn’t take the pills — showing a real connection between vitamin D in the blood and muscle changes.
