Gut health depends on nervous system health.

Chicken or the egg

If you have gut issues of any sort you likely have autonomic nervous system imbalance. When the nervous system isn’t in its most functional space other systems shut down. They don’t work the way they were designed. Once it’s back in ventral vagal (the elephant) it sends the message to the gut to do its thing. So if you suffer from IBS, Chronic Constipation etc you may want to look at your nervous system.
