Vitamin D and the Immune System

Wow, interesting explanation of the roles of Vitamin D in the immune system. You can skip the bone stuff at the beginning. He explains exactly how Vit D affects the Innate immune system and how it steers the Acquired immune system toward the anti-inflammatory direction. Without it, the Acquired immune system can generate cytokine storm that is killing a lot of seriously ill patients. I knew Vitamin D was helpful, but I had no idea it prevents cytokine storm!
