As a diabetic of 43 years, I've done pretty well. I can still see and pee and have all my feet and toes. I recently learned how high dose vitamin C can get rid of those age spots that mar our complexion as we get older. I had a big dark spot on my face go away and today I looked down at my feet and one of two scars was gone and the other was going. They had been there for several years. and They say diabetics don't heal well. Our bodies need Vitamin C to make collagen and to keep our skin healthy we all need more than the RDA, but Diabetics even more so. Diabetics use up our vitamin C quicker than most other people and it is a strong anti-oxidant. Even though I am doing fairly well, I did have a Heart attack 10 years ago. My arteries were brittle and since I wasn't taken vitamin C at that time, my body didn't have the materials to repair and keep my arteries flexible. I take this C and I also take another Liposomal Vitamin C 1:1. I have taken up to 40,000 mg in a day spread out throughout the course of the day. Like 2,000 and hour. No ill effects and with some pleasant surprises such as I described
