Gut Microbiome As A Modifiable Organ
- The gut microbiome is a modifiable 'forgotten organ' that influences mood, energy and cognition.
- Changing your microbiome gives a practical way to improve health without altering your genes.
The Gut Is A Living Ecosystem
- Your gut hosts trillions of organisms (bacteria, viruses, yeast, fungi) that make molecules impacting distant organs.
- This living ecosystem actively responds to your diet and lifestyle in real time.

- Gut microbes communicate with the brain via the vagus nerve and microbe-produced metabolites.
- Short-chain fatty acids made only by microbes reduce inflammation and support the blood-brain barrier.
