Short conversational YouTube video (Gary Brecka interviewing another speaker) arguing that the gut is the root cause of many diseases. Speakers state a seven-stage model of disease with gut problems as stage one and severe conditions (cancer, autoimmune, neurogenic disease, diabetes) as later stages. The guest claims ~92% of serotonin is produced in the gut, links gut health to hormones and energy, and recommends peptides (described as messenger molecules that restore biology) over direct hormone replacement. A question about peptide administration for cognitive improvement appears near the end.

All diseases start with the guts and end with the guts. There are seven stages of diseases. Stage seven is cancer, autoimmune disease, neurogenic disease, diabetes. Stage one is gut problems.
I agree with you that the gut can be the root of all evil.
92% of your serotonin is created in the guts. Your hormones, your energy. In the gut, you clean that. Suddenly you have more energy to fight any other problem yet you have.
And sometimes you.
Use peptides.
To optimize hormones.
Before actually taking peptides, you want to make sure your body will actually accept it and make it stronger. Peptides are messeng molecules, while if you take hormones it overrides your own biology. Peptides don't override, they bring it just back to how it should be.
So for people that are looking to improve cognitive function, how are these peptides administered?
If your hormones are not imbalance, my advice will still be.
Ultimate.
