Low mood. Brain fog. Anxiety.
Before you look only at your psychology — look at your gut.
Hippocrates said "All disease begins in the gut" around 400 BC. For most of medical history that was treated as a poetic metaphor from a man without a microscope.
Then science caught up.
Your gut contains approximately 500 million neurons — more than your spinal cord. It produces around 90% of your serotonin. Your primary mood chemical. Not in your brain. In your gut.
The gut and brain communicate constantly and bidirectionally through the vagus nerve. Researchers now call this the gut-brain axis.
Ayurvedic medicine called it agni — digestive fire — and placed gut health at the centre of all health five thousand years ago.
Modern gastroenterology essentially agrees.
Different language. Same conclusion.
This is the Metabolism pillar of the M3 System. Ancient wisdom. Backed by modern science.
