The Claim
In rats, overexpression of the vitamin D receptor (VDR) is associated with upregulation of extracellular matrix (ECM) remodeling gene-sets, including those involved in collagen formation, integrin signaling, and matrisome components, which suggests that VDR may facilitate muscle hypertrophy by enhancing structural support and force transmission.
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.
In rats, having more of a protein called VDR seems to turn on genes that help build stronger muscle scaffolding, which might help the muscles grow bigger and work better.

What the research says
1 studyStudy: Overexpression of the vitamin D receptor (VDR) induces skeletal muscle hypertrophy
Scientists made rats produce more of a protein called VDR in their muscles, and those muscles got bigger and stronger — partly because the scaffolding around the muscle fibers (called ECM) got stronger too, helping the muscles work better.
