Xlear began when Dr. Alonzo H. Jones, D.O., a family physician in west Texas, was trying to find a solution for the people coming to see him for upper respiratory issues. He studied the research pointing to the benefits of xylitol for improving oral health and its effects on bacteria. He noted that upper respiratory problems had been steadily increasing since the early 1970s, owing to environmental factors that included poorly conceived drug therapy and growing antibiotic resistance. He also understood that most upper sinus and respiratory problems were linked to chronic, inadequate nasal hygiene. Studies show that 90% of moisture and bacteria enter through the nose. He set out to find a preventative treatment to address these growing problems. The solution was Xlear. Today, the company is recognized as the leading manufacturer of xylitol-based products in North America. They are tirelessly committed to providing consumers with the health benefits of xylitol, erythritol, and other natural sweeteners by manufacturing natural, health-enhancing xylitol products based on these incredible sweeteners found in wood, fruits, vegetables, and other natural sources. One of their most popular Xlear products is Xlear Adult Nasal Spray.
