Vitamin D may help improve muscle recovery after nerve injury

Posted on: June 24, 2013   by  Rebecca Oshiro


In a new animal model, researchers in France report on a detailed look at how and if vitamin D plays a role in nervous system:

Chabas JF, Stephan D, Marqueste T, et al. Cholecalciferol (vitamin d3) improves myelination and recovery after nerve injury. PLoS ONE. 2013;8(5):e65034.

In a past study, this same research group found that vitamin D improved nerve regeneration after injury and increased the diameter of nerve fibers in rats. While the results of this previous study were exciting, the researchers wanted to explore this animal model further before recommending that the same type of research be carried out in humans, too.

In particular, they wanted to know which form of vitamin D was most effective, how much and how safe different doses are, and which genes would be affected by vitamin D.

    To Rebecca:
    Thanks for bringing this article to our attention. It may go along way in convincing some of my relatives of the importance of Vitamin D.

  2. Rebecca Oshiro

    You are welcome, IAW. This study has interesting implications for future studies in people.

  3. Rick

    Interesting study. How would that high a dose in rats translate over to humans? Do you know if they are going to study humans with neuromuscular injuries treated with different size doses of D-3?

    Rick, a rat taking 500 IU of vitamin D per kilogram of body weight per day is equivalent to a 220 pound adult male taking 50,000 IU of vitamin D per day.
