VitalSleep is a US-based company that proudly makes its flagship anti-snoring mouthpiece in America. This snore relief mouthpiece is the #1 anti-snoring aid due to the fact that it is completely customizable. Every person has a unique mouth shape and bite. That is why it's important to have a device that fits your specific mouth. VitalSleep offers a boil and bite method to ensure that the snore solution mouth guard fits comfortably every night. In addition, the device also allows you to adjust the lower tray of the mouth piece up to 8mm to provide the perfect amount of lower jaw movement needed for you individually. This method has been scientifically shown to improve breathing during the night by opening the airway and keeping the throat from falling back and restricting airflow. But if the jaw advancement is not perfect, it can be too uncomfortable to wear throughout the night. VitalSleep is the only snoring solution that allows you to make micro-adjustments until you find the precise size that works best for you. During the product process, we use strict production guidelines for your wellbeing to create a safe and trustworthy product. VitalSleep does not contain any BPA, latex, or metal. Your health and safety are our top priority. Overall, VitalSleep is the most trusted anti-snoring mouthpiece that will give you the power to breathe easily and sleep quietly
