So, I'm so excited to post this. I took 5,000 milligrams of Vitamin C and 40,000 IUs of Vitamin D in divided doses every day for six months or so during this past winter. I took it so that I wouldn't get flus or colds. Well, I didn't get any. This is the first time since 1997 that I haven't gotten a flu or cold in the winter. I noticed that I would always come down with something in Feb or March and assumed it was because my D was low. And not only that, but I just came back from the dentist and the dentist said I have reversed my gum problems! Just six months ago I had a gum infection and also had to get two fillings for gum recession. He said to keep doing what I was doing. I had to think--I did take CoQ10 but I was taking it on and off before. And then it hit me--it has to be the C and D.
