Under Armour has developed a performance mouthguard called ArmourBite that is designed to enhance athletic performance. It works by reducing jaw clenching during stress, which lessens the release of cortisol. Less cortisol leads to benefits like increased strength, endurance, and reaction time. Extensive research over 10 years at major universities has shown its effectiveness. Many professional and Olympic athletes have used ArmourBite and reported improvements in areas like power, focus, endurance and accuracy.
