The Role of Vitamin D in Muscle Building


Most of us are aware that Vitamin D assists in the uptake of calcium in the body and that calcium is absorbed better in the presence of vitamin D. Vitamin D can also help to protect against certain types of cancer as well as cardiovascular disorders.

Additionally, Vitamin D has been found to boost the levels of testosterone in a natural way. Now, Charles Drew University in Los, Angeles, California believe that they have found another positive aspect of vitamin D. Researchers at Charles Drew have found that–at least in vitro testing–vitamin D can actually help to speed the development of the muscles.

Many different theories exist about the promotion of muscle growth and development. In fact, due to the desire of athletes and body builders for better muscle growth and tone, more testing has been done and more theories arrived at nearly every day.

One theory which has definite merit is that exertion of any kind has a stimulating effect on the muscles. This is due–at least in part–to the fact that the physical exertion stimulates the stem cells to develop into mature cells if they are of the muscular type.

There are other theories that if you [i]consume broccoli as well as leafy vegetables such as cabbage, that this process can be stimulated. This theory has been called a “hare-brained”theory.

There is another theory that shows that a “good radical” [ii]NO, or Nitrous Oxide has some effect on the muscle growth process. There is some evidence which states that NO can help to mediate the activation of satellite cells which helps to repair or to induce the growth of muscle.

Vitamin D has long been under study because it has been known that if older people were given vitamin D, they grew stronger. Ultra Violet radiation in the elderly, a process which helps to synthesize the production of vitamin D, also increases strength in the elderly.

Now studies are showing that vitamin D, when given to lab animals which were actually being fattened, they developed more muscle than fat.

There is a strong reason to suppose that the same will hold true of humans.Typically, the more vitamin D which is in play in the human body, the better quality of muscle tissue they will develop.

Researchers—in an attempt to determine the process which was responsible for the positive changes, did a full series of experiments with cells taken from mice. The cells, the C2C12 cells, also called myoblasts, are the stem cells from which muscle tissue is created. These cells begin to divide when any muscle tissue has undergone damage.

The cells were then exposed to vitamin D in the test tube. Calcitriol actually sped up the production of the muscle fiber in their research experiments, lowering the production of myostatin and increasing the production of IGF2 as well as Myog and MyoD.

The conclusion which was reached by the researchers was that “”This study provides a mechanistic justification for clinical studies to examine the administration of active vitamin D and/or novel VDR activators (to avoid the hypercalcemic side effects) and even the potential role of emerging therapies directed to trigger select vitamin D-regulated muscle pathways in the treatment of adverse muscle conditions”

Additionally, it is important to note that the research was not funded by any company which provides or sells supplements.
