The Claim

Ablation of the vitamin D receptor in mice results in altered expression of myogenic regulatory factors (MRFs), which indicates disruption of muscle development or regeneration pathways.

These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.

How it works
1 study reviewed
In plain English

When scientists remove the vitamin D receptor in mice, the genes that help muscles grow and repair don't work right anymore, which might mess up how their muscles heal or develop.

  1. Study: Vitamin D Receptor Ablation and Vitamin D Deficiency Result in Reduced Grip Strength, Altered Muscle Fibers, and Increased Myostatin in Mice

    Scientists removed the vitamin D receptor in mice and found that their muscles didn't develop or repair properly because key muscle genes went haywire — exactly what the claim said would happen.
