TheraBreath PLUS Nasal-Sinus Drops take the power of our TheraBreath PLUS formula to your nasal and sinus cavities, where bad breath bacteria can hide and breed. Dr. Katz’s Maximum Strength PLUS Nasal-Sinus Drops are loaded with powerful ingredients that neutralize odor-causing bacteria, food odors, and morning breath. They are specially formulated to be easier on your nasal passage, where bad breath bacteria feed on mucus. They are non-habit forming and a perfect solution to the bad breath caused by the post-nasal drip associated with seasonal allergies. These nasal-sinus drops include xylitol, green tea antioxidants, aloe vera, and tea tree extract. TheraBreath PLUS Nasal-Sinus Drops contain no alcohol, artificial flavors, or colors. They are also certified kosher, gluten-free, and vegan. Xylitol and green tea are among nature’s most powerful antimicrobials and have been shown to be extremely effective at eliminating various anaerobic sulfur-producing bacteria that can cause severe bad breath. Our nasal-sinus drops deliver this powerful formula to your nasal and sinus cavities, where no oral rinse could reach!
