Description

Problems with SIBO? Looking for a natural approach to a solution? We've got you covered. 

Oil of Oregano and Ginger Extract are two vital components to addressing Small Intestinal Bacterial Overgrowth (SIBO). 

Have you noticed intense sugar cravings? Bad breath or that funky white growth on your tongue? GutRx Overgrowth is designed to calm down an overgrowth in the system and promote a healthy balance. 

This is not meant to be taken every day unless symptoms are present. GutRx Overgrowth is a great addition to keep in the refrigerator for when these bacterial overgrowth symptoms occur. It even helps when you're dealing with a sickness, like the flu or cold!

100% all-natural approach to addressing imbalanced bacteria in the body. 

How to Use

Take 1 capsule daily with water, preferably with a meal, for optimal digestive balance.

Overgrowth combines targeted probiotics with botanicals like oregano oil. I use it as a focused course when the goal is rebalancing, not everyday maintenance.
