is vitamin C, right? You know vitamin C is important. Probably at the first sign of the cold,

you might take vitamin C. What does vitamin C do to the immune system?

Well, number one, it increases the mobility of white blood cells. It makes them more active. And without vitamin C,

your blood and compared it to the vitamin C in the white blood cell, the vitamin C in the white blood cell
