Based on my low blood sugar problems of years ago, I wouldn't consider any supplements that lower blood sugar too much because of the danger of too low numbers if you have a spell. In the 1970's my doctor seemed to understand little about low blood sugar and only told me to eat often and carry cheese. A paramedic explained what was happening to my body, and I learned to eat six times a day and cut the carbs, although I didn't know why it helped. A nutrition book I read at the time said people with low blood sugar are neurotic. My reply was that low blood sugar can make a person neurotic, as it is really scary to be dizzy and not know what you are doing. I finally realized that my episodes were triggered by stress and with stress control and eating changes, the problem went away. I have eaten every four hours ever since and was surprised when diagnosed with diabetes years later. So I would not consider supplements that lower blood sugar as a regimen without depending on diet and exercise as the essential plan for controlling blood sugar. It gets easy and improves health generally, and I don't consider myself a sick person. At age 85, I am outliving my friends. Dorisena
