Vitamin A: Muscle Development

Since vitamin A plays an important role in several tissue functions, including muscular, consuming proper amounts can indirectly build muscle mass. Supporting your muslce cell metabolism, vitamin A allows cells to digest fatty acids as a fuel agent. In addition, this vitamin could also effect the rate of muscular turnover, which effects the bodys ability to grow muscle tissue. A 2010 study in the Journal of Nutrition indicated that vitamin A contributes in the regulation of muscle protein breakdown in rats. Thus, vitamin A deficiency resulted in muscle protein breakdown. Although animal studies can not be completly apllied to humans, the study suggests that lacking diets in vitamin A could effect the ability to grow new muscle tissue, thus preventing overall muscular growth.

One form of vitamin A, retinoic acid, has been linked to the regulation of new muscle growth. Physiologically, muscle tissue contains progenitor cells, known as satellite cells. When these satellite cells mature, the upbring new functional muscle cells. In 2009, a Canadain study found that vitamin A produces new satellite cells, which indicates that vitamin A plays a role in new muscle tissue growth. Overall however, there has been no indication whether these new satellite cells fully mature in muscle cells. In addition, vitamin A is involved in the production of Glycogen, which is the body's storage for energy in high intensity exercise.
