KETO CURB uses the science of epigenetics to biohack your appetite and satiety genes. This 100% all-natural formula is clinically proven to reduce appetite and support weight loss. KETO CURB contains a newly developed ingredient called DNF-10™, which is derived from Saccharomyces cerevisiae – a yeast species from the fungi (mushroom) kingdom. It reduces hunger cravings by acting on the gut-brain axis (digestive system and hypothalamus) and reduces the hunger hormone ghrelin and increases the satiety hormone leptin.
