I started taking Vitamin C because I heard that mega-dosing on it helped with remyelination of nerve cells. Two other side effects resulted. First I lost about 20 pounds in two months. I didn't really change my diet or exercise any more than usual. Also, I noticed that I was not suffering from my seasonal allergies. Normally I get seasonal allergies in May and late summer. This past may I only took one over the counter pill. So far this summer I haven't had to take any.
