🔥 GI ABSORPTION 101: WHERE NUTRIENTS ACTUALLY GET IN — AND WHAT ANTACIDS STEAL FROM YOU

Your gut isn’t a trash chute. It’s a precision machine.

Each section is built to absorb different nutrients…And when you shut off stomach acid with antacids, the whole system gets confused.

🧪 Stomach — The Acid ChamberProtein digestion begins here .Acid “unlocks” minerals so you can absorb them later. Low acid = low: Iron, B12, Calcium, Magnesium, Zinc

⚡ Duodenum — The Mineral Highway Absorbs the minerals the stomach prepped. Blocked upstream? Everything slides by.

🥗 Jejunum — Your Main Grocery Store Where most nutrients enter your bloodstream: Amino acids • Carbs • Fats • Electrolytes • B-vitamins

🎯 Ileum — The B12 Specialist. If you rely on antacids, B12 may never make it to the ileum for absorption. Cue: fatigue, neuropathy, anxiety, brain fog.

🌿 Colon — Microbiome Territory Absorbs water + electrolytes Your microbes make SCFAs (fuel for colon cells), not vitamins.

⚠️ WHY ANTACIDS DERAIL THIS Long-term PPIs/H2 blockers turn off the acid switch →Minerals stay bound → B12 stays stuck → proteins don’t break down → absorption tanks.

It’s like shutting down the first tool on an assembly line and wondering why the final product looks defective.
