StrixNB is a safe and effective drinking water additive to help maintain and promote good dental and oral hygiene for pets. StrixNB is xylitol-free, made using 100% human food grade ingredients. StrixNB works against dental disease-associated bacteria by altering the mouth’s environment. It breaks through dental biofilm, a highly structured, matrix-embedded microbial population, leaving bacteria otherwise inaccessible exposed for eradication by a microbial agent. Ingredients: Water, Sodium Citrate, Citric Acid, Disodium EDTA, Potassium Benzoate and Zinc Chloride.
