We usually hear about how the brain affects the gut, but Dr. Barrett flips the script to explain how your gut directly shapes your brain. He breaks down the enteric nervous system (your “second brain”), the vagus nerve as a two-way communication highway, and why 90-95% of your serotonin is actually produced in your gut. He covers five ways an unhealthy gut can drive anxiety, depression, and brain fog, then closes with five practical strategies to repair the gut-brain connection… plus his top pick for a gut-optimizing supplement: butyric acid.. . . Watch the episode on YouTube here!

For decades, "high cholesterol" has been treated as a diagnosis in itself - but Dr. Barrett breaks down why that's outdated thinking. Using advanced lab markers now available through services like Function Health, he walks through five common cholesterol myths: that high cholesterol equals heart disease, that LDL-C tells the whole story, that high HDL is automatically protective, that diet alone drives your LDL levels, and that a normal total cholesterol means low risk.
