Gut-Health

The gut-brain serotonin pathway is the mechanism behind mood swings, anxiety, and brain fog that start in your digestive system.

IBS affects 10-15% of adults — and the functional medicine approach targets root causes rather than just managing symptoms.

Your gut bacteria don’t just digest food — they literally control which of your brain genes get expressed.

The gut-brain connection is more specific than you think — new research maps the exact pathways your gut bacteria use to influence your mental health.

Your gut sends signals to your brain through the vagus nerve — and gut bacteria control what those signals say.

The immune pathway from gut inflammation to brain fog runs through cytokines and microglial activation — and it’s more direct than you think.

Your mouth harbors bacteria that can reach your brain through your bloodstream, a cranial nerve, and your gut — here’s how the oral-gut-brain axis actually works.

The oral-brain connection runs through bacteria, nerve pathways, and inflammation — and your mouth health directly shapes your cognitive function.

The vagus nerve carries 80% of gut-to-brain signals — and you can actively strengthen its function through specific practices.

New research maps exactly how bacteria in your mouth reach your brain and contribute to cognitive decline — and the connection is more direct than anyone thought.

Your gut bacteria make butyrate from fiber — but not all fiber works the same way. Here’s what to eat, what to skip, and whether supplements are worth it.

The rise, fall, and resurrection of a drug designed to block gum disease bacteria in the brain tells you everything about where Alzheimer’s research is heading.
