ExtendSnacks were designed to do one thing particularly well - help stabilize blood sugar levels for up to 9 hours. ExtendSnacks were invented by Francine Kaufman, M.D., past president of the American Diabetes Association, author of the book Diabesity, and world-renowned endocrinologist. ExtendSnacks are made with the only formula clinically proven to help control blood sugar for up to 9 hours. All ExtendSnacks can be helpful for people with diabetes, people looking to live healthy, people managing their weight, or anyone looking for sustained energy.
