Sculpt and maintain a strong jawline by making ROCKJAW® Stackables Tough Mastic Gum part of your daily routine. Back in the day, cavemen chewed on mastic, but with softer foods prevalent in modern times, jaws aren't getting the exercise they used to. As a result, jaw strength and size have decreased, and our biting force has weakened. Mastic chewing gum offers resistance training for our jaw muscles, improving jawline development, bite force, and even promoting nasal breathing. Its antimicrobial properties promote better dental hygiene and help eliminate bad breath.

This gum is 10 times stronger than regular gum and can be re-chewed twice for continued satisfaction. Hand-selected and made with 100% natural ingredients, it contains no sugar, sweeteners, aspartame, or soy. Our stackable solid crystals offer a more controlled chewing experience and come in 20g tins. All our mastic gum is refrigerated to ensure it stays as fresh as possible.

Also Included with purchase is free one-on-one support via Instagram (@rockjawuk).
