Berberine acts as a potent herbal antibiotic. It is often used in functional medicine protocols to clear Small Intestinal Bacterial Overgrowth (SIBO) and Candida, while largely sparing beneficial commensal bacteria.

Many "gut issues" are actually "stomach issues." Without sufficient acid, proteins putrefy in the intestines (causing bloating) and pathogens survive passage to the small intestine (causing SIBO).

The gelatin in bone broth is hydrophilic (attracts water), helping to maintain the mucus layer that protects the intestinal wall from bacteria. Its high glycine content also helps regulate stomach acid production.

Collagen is unique because of its high content of Glycine and Proline. These amino acids are essential for healing the gut mucosa. Hydrolyzed peptides are easily absorbed and transported directly to connective tissues.

Food sensitivity tests are often inaccurate. The only definitive way to know if a food causes inflammation is to remove it for 30 days and reintroduce it. This creates a "clean slate" baseline for the immune system.

The MMC is a cleansing wave that sweeps bacteria and debris from the small intestine into the colon. It only activates when you are in a fasted state (at least 3-4 hours between meals). Constant snacking paralyzes this cleaning crew.

A 2021 Stanford study showed that a high-fermented food diet increased microbiome diversity and lowered inflammatory markers (like IL-6) more effectively than a high-fiber diet alone.

Enterocytes turn over every 3-5 days. L-Glutamine provides the energy required for this rapid regeneration. High-dose supplementation (5-10g+) has been shown to significantly reduce intestinal permeability triggered by stress or infection.

Magnesium draws water into the intestine to keep stool soft and supports the muscle contractions of peristalsis. It also calms the nervous system, aiding the Vagus nerve.

Omega-3 fatty acids increase the abundance of anti-inflammatory bacteria (like Bifidobacterium) and decrease LPS-producing bacteria. They also serve as precursors to resolvins that heal the gut lining.

You cannot simply take probiotics; you must create an environment where they thrive. Prebiotics feed keystone species like Akkermansia muciniphila, which thickens the protective mucus layer of the gut.

Stress causes the release of Corticotropin-Releasing Hormone (CRH), which directly degrades mast cells in the gut, causing them to release histamine and loosen tight junctions.

Digestion is a parasympathetic process. If the Vagus nerve is underactive (due to chronic stress), the pyloric valve won't open, enzymes won't release, and food sits stagnant. Activating the Vagus is the "on switch" for digestion.

Vitamin D deficiency is strongly correlated with Inflammatory Bowel Disease (IBD) and compromised barrier function. It helps the immune system tolerate beneficial bacteria while fighting pathogens.

Zinc Carnosine is a specific form of zinc shown to stabilize the gut mucosa and prevent damage from NSAIDs and alcohol. It literally "tightens" the junctions between cells.

When the gut barrier is leaky, endotoxins (LPS) enter the blood, causing "metabolic endotoxemia." This drives up hs-CRP. healing the gut often results in a dramatic drop in systemic inflammation.

Your bacteria have a circadian rhythm too. Disrupted sleep cycles alter the composition of the microbiome (dysbiosis), favoring inflammatory species and increasing gut permeability.
