A comprehensive four-stage digestive enzyme complex combining hydrochloric acid, pepsin, pancreatic enzymes (amylase, lipase, protease), ox bile, and betaine — replicating the full digestive cascade from stomach to small intestine so your body can break down proteins, fats, and carbohydrates the way it was designed to before age, stress, and medication slowed it down.
You eat well, but something is not landing. Bloating after meals, heaviness that lingers for hours, the feeling that food is sitting rather than digesting. You might notice it more after rich or protein-heavy meals, or it might have become so constant that you have forgotten what comfortable digestion feels like. You have tried cutting foods, eating smaller portions, chewing more slowly — and while these help at the margins, the underlying pattern persists. The problem is rarely what you eat. It is how efficiently your body breaks it down.
Digestive enzyme production declines naturally with age. By your thirties, hydrochloric acid output begins to decrease. By your forties and fifties, pancreatic enzyme secretion may have dropped significantly. Stress diverts blood flow away from the digestive tract, suppressing secretion further. PPIs and antacids — among the most commonly prescribed medications in the UK — deliberately reduce stomach acid, which impairs the protein digestion that depends on it. Gallbladder removal eliminates the reservoir that concentrates and releases bile for fat digestion, leaving many post-cholecystectomy patients struggling with fatty foods for years. The result across all of these scenarios is the same: food arrives in the small intestine insufficiently broken down, nutrients are poorly absorbed, bacteria ferment what should have been digested, and the gas, bloating, discomfort, and heaviness follow predictably.
Thorne Advanced Digestive Enzymes addresses every stage of the digestive cascade in a single capsule. Betaine HCl restores the stomach acidity needed to activate pepsin and initiate protein breakdown — the critical first step that declining acid production compromises. Pepsin, the primary gastric protease, cleaves proteins into peptides that downstream enzymes can process. Pancreatin provides a complete suite of pancreatic enzymes — amylase for carbohydrate digestion, lipase for fat digestion, and protease for further protein breakdown — replicating the enzymatic output of a healthy pancreas. Ox bile emulsifies dietary fats, compensating for reduced bile production or absent gallbladder function, and enabling lipase to access and break down fat molecules efficiently.
Betaine additionally contributes to normal homocysteine metabolism, supporting methylation pathways alongside its digestive role. 180 capsules per bottle — a 60-day supply at the recommended three capsules daily.

People who understand that nutrient absorption begins with digestion, not supplementation, choose comprehensive enzyme support rather than adding more vitamins and minerals to a system that cannot extract what it already receives. It reflects a foundational approach — fixing the process before adding to the inputs.
You gain complete protein breakdown, which removes the bloating and heaviness caused by undigested protein fermenting in the gut and enables efficient extraction of amino acids from every meal.
You gain fat digestion, which removes the discomfort, loose stools, and malabsorption that follow fatty meals — particularly post-cholecystectomy — and enables proper emulsification and absorption of dietary fats and fat-soluble vitamins A, D, E, and K.
You gain carbohydrate processing, which removes the gas and fermentation produced when starches and sugars pass undigested into the lower gut and enables clean energy extraction from complex carbohydrates.
You gain nutrient absorption, which removes the paradox of eating well but remaining deficient and enables your body to actually access the vitamins, minerals, and macronutrients present in your food.
You gain post-meal comfort, which removes the bloating, heaviness, and lethargy that turn meals from fuel into burden and enables the kind of effortless digestion you stopped noticing because you forgot it was possible.
