Purchase one GlutaStat and receive a bottle of GlutaStat NS at 20% off. Only good for 3 combo’s please. Folks find the GlutaStat best for nebulizing ( please see you health care professional) and the GlutaStat NS is a more concentrated product which can really reduce bacteria, virus or fungus in the nasal passages and sinus. Dr. John often has his patients use both for more sever cases or to speed up the process of recovery. The ingredients in GlutaStat have been shown to work against a broad spectrum of infections therefore it is effecting for most cases.
