I have tried many, many products to reduce and normalize my blood sugar. I have a damaged immune system from " shots" when I was a small child, thru which I have rheumatoid arthritis and three damaged heart valves. Doctors at that time directly verified this. Now at 61, I have blood sugars sometimes at highest readings when I do not have this product. Others may help a little, but with them I never see under 200. Diatrol, as it is currently formulated, will bring it down and keep it down at a safe level, of course, as long as I behave and stay away from high carbs and sugar. My gratitude goes to those who helped develop and market this product.
