Approximately 15% of our intestinal lining is composed of enteric endocrine cells.

These cells produce over 90% of the serotonin and over 50% of the dopamine neurotransmitters. This means the brain does not produce its own neurotransmitters, the gut does.

This is a massive paradigm shift in the current ideology of the brain’s functions.

It's not surprising that damage to the microbiome and intestinal lining is commonly associated with neurologic diseases such as autism, depression, and anxiety.

The gut barrier is the first line of defense against intestinal pathogens and toxins. It is responsible for the carefully regulated passage of water, electrolytes, macro-, and micronutrients from our diet. In order for our bodies and minds to function properly, our gut must do so first.
