Happy Belly (formerly known as Microbial Maintenance) is a proprietary blend of anti-microbials and botanicals that help support normal balance of the GI Tract. The disruption of this balance, known as dybiosis, can lead to uncomfortable digestive symptoms, and interfere with proper nutrition and immune function. This formula, designed in collaboration with MetaMetrix labs, has the ingredients found most effective for restoring balance in the gut based on stool sample analysis. Probiotics are highly recommended following the use of Happy Belly.*
