The Claim

The effects of vitamin D receptor ablation and dietary vitamin D deficiency on muscle strength and gene expression in mice occur independently of calcium, magnesium, and phosphate levels, as these were experimentally controlled.

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.

How it works
1 study reviewed
In plain English

Even if the levels of calcium, magnesium, and phosphate in the mice’s bodies were kept the same, removing the vitamin D receptor or not giving them enough vitamin D still changed their muscle strength and which genes were active.

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

    Even when the mice had normal levels of calcium, magnesium, and phosphate, removing vitamin D or its receptor still made their muscles weaker and changed their muscle genes — proving vitamin D affects muscles on its own.
