Oral GABA likely crosses the blood-brain barrier poorly, so lifestyle approaches, exercise, and GABA-supporting herbs may be more meaningful levers.

Prebiotics feed beneficial gut bacteria. Inulin, FOS, and resistant starch have the most trial support, though gradual introduction matters to avoid gas.

Enteric-coated peppermint oil has strong meta-analysis support for IBS symptoms, while ginger, fennel, and caraway offer additional digestive relief.

Digestive symptoms, sleep disruption, skin issues, and frequent illness can all trace back to gut health. Here are the evidence-backed signs worth watching.

Stomach acid production, digestive enzyme output, and gut motility all shift with age. Here's what's actually changing and what helps.

DGL licorice showed clinically significant symptom improvement within two weeks in a placebo-controlled trial. See the evidence for DGL, melatonin, and lifestyle factors.

Intestinal permeability is a real, measurable phenomenon, but "leaky gut syndrome" as a standalone diagnosis remains contested. Here's what's established vs. speculative.
