Therefore, vitamin D may affect blood sugar metabolism. In turn, deficient levels of vitamin D are associated with greater resistance to insulin.

muscle function

In recent studies, vitamin D has been studied for its involvement in skeletal muscle function. It has been concluded that adequate amounts are linked to an improvement in muscle quality. In addition, the implication of vitamin D in the activation of protein synthesis has been studied.

Although getting enough vitamin D is important for maintaining healthy bones, mechanical load is also an important factor. The loads generated by walking and running are important because they play an important role in the cellular processes that control bone maintenance.

Current research does not support the idea that this vitamin causes weight loss, but there appears to be an association between vitamin D and weight.
