Loving the new gum with caffeine. I use the hard gums already for a long time and the bonus of the caffeine is so good. I had a lot of normal caffeine gums in the past, in terms of bitterness and taste jawliners caffeine gum is one of the best.

am giving this product 3 stars because it delivers what it promises: a high-resistance workout for your masseter muscles combined with a quick energy kick. The gum is significantly harder than normal chewing gum, and you can feel it working your jaw almost immediately. Because the caffeine absorbs through your mouth, the alertness hits you much faster than drinking a cup of coffee or a pre-workout shake.The only reasons I am knocking off two star s are the flavor and the palatable feel for strain. The taste drops off pretty quickly, and the caffeine can leave a quite a bitter notes afterward. You also have to be very disciplined with the timing—if you chew this for more than 15 minutes, your jaw will definitely ache the next day. Overall, it is a good, high-utility tool for jaw training and focus, just make sure to follow the instructions and don't overdo it.
