What does Premium Medical Grade Manuka Honey do for your digestive care? Medical Grade Manuka Honey provides a drug-free solution to keep the gastrointestinal tract healthy and the immune system strong. Through stimulating a natural immune response, Medical Grade Manuka Honey kickstarts antibody production and inhibits c-reactive proteins, particularly in cigarette smokers, who suffer more internal issues than non-smokers do. Certified Medical Grade Manuka Honey also serves a prebiotic function in the intestines, “feeding” healthy gut flora to support a strong microbiome and support overall Gut Health. Produced in New Zealand by bees who pollinate manuka bush flowers, MGO 400 Medical Grade is a highly-filtered and pasteurized honey that is more effective than raw honey; it has been gently heated, leaving all its natural enzymes and proteins intact. Manuka Honey, unlike all other honey, tolerates heat very well.
