WHAT DOES VITAMIN D DO?
Vitamin D’s actions are best understood in its role in calcium metabolism. Without it a person is not able to absorb the calcium in his or her diet or maintain the proper balance of calcium and phosphorus to build and maintain bones. Lack of vitamin D can also cause over stimulation of the parathyroid gland and muscle aches and weakness.
Vitamin D is also metabolized and has activity in many other tissues. Its functions appear very important to a number of basic immune system processes. These are areas of active research. Definitive claims or conclusions about these processes are premature.
