Performance gum? Yes! Run Gum was developed by a two-time Olympian and biochemist and is designed to give you an energy boost of caffeine that is equivalent to a half cup of coffee or energy drink. Convenient individual packets with 2 pieces of gum, chew one before your run or workout, then maybe one when you’re done, are available in mint and fruit flavor. We found that it gave us a little extra oomph without weighing us down and with no problems of jitteriness or a crash that we sometimes get after an energy drink. It’s zero calories and gluten free too. As they say, a “smarter caffeine kick for athletes”.
