It's not something I have tried personally but it has a lot of positive reviews behind it. It's used to increase muscle insulin sensitivity and lower blood glucose levels after meals. Increasing muscle insulin sensitivity is very important. Here are 3 things I do on a regular basis
1. Cinnamon is a great spice that increases insulin sensitivity.
2. Chromium is a very important trace mineral that increases insulin sensitivity.
3. Adding apple cider vinegar to your meals will lower the glycemic load of the meal and increase muscle insulin sensitivity.
