How does it enhance workouts?
Scientifically, it’s a central nervous system stimulant that temporarily blocks a brain signal (adenosine) that makes you feel tired.
It enhances how alert you feel and how hard exercise feels, which is why it can boost performance.

"Love the jolt of energy I get. This gum has a good flavor, good consistency and lasts about 20 minutes. It works in about 10 minutes and is faster than drinking an energy drink or soda."

"I love how easy it is just to chew a piece of REV gum when you need a quick energy boost! I’ll chew it before I workout, before a long conference call and sometimes even before my kids wake up from a nap. 🤪 It’s the best pick me up!"
