Leading “Gut-X Axis” innovation

Prebiotics, probiotics, and postbiotics aren't just for gut support anymore. Our research has found that our gut communicates with our entire body and can support specific organs with targeted benefits through our blood vessels and lymphatics. At res, we call this the Gut-X Axis. As the target benefit, the ‘X’ could stand for the lungs, as in the gut-lung axis, the heart, as in the gut-heart axis, or the brain, as in the gut-brain axis.

The possibilities are endless. The Gut-X Axis is our foundation.
