Microbiome

The bacteria in your gut teach your brain’s immune cells how to behave. Here’s the microbiome-microglia connection, minus the hype.

Functional medicine treats the microbiome-sleep link as a one-way street. The research says it’s a loop — and that changes what actually works.

A growing body of research links gut-driven inflammation to depressive symptoms — and that changes what actually helps.

You don’t just have one body clock — your gut bacteria keep their own time, and when the two drift apart, sleep and energy pay for it.

The fibermaxxing trend is everywhere — but what happens when fermentable fiber hits a gut that isn’t ready for it?

The gut-brain connection is real, but what actually works? Evidence-based probiotics, butyrate, diet, and testing strategies for mental health.

Your gut bacteria are waiting for fiber you’re not giving them. Here’s how prebiotic foods produce anti-inflammatory compounds — and what happens when you finally deliver.

The fibermaxxing trend is everywhere — but the research on fiber supplements vs whole food fiber tells a different story than influencers suggest.

The fibermaxxing trend gets the premise right but the method wrong — and for disrupted guts, it backfires.

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.

The tryptophan-serotonin pathway your gut bacteria run — and what happens when it stops working.

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