Digestive Enzymes & Nutrient Absorption Hub
A comprehensive root cause resource covering digestive enzyme science, macronutrient digestion, nutrient absorption mechanisms, conditions that impair absorption, enzyme optimization, and systemic connections.
Category 1: Digestive Enzyme Foundations
What Are Digestive Enzymes? A Root Cause PerspectiveUnderstand what digestive enzymes are, where they come from, and why enzyme insufficiency is a root cause of chronic digestive and systemic health problems. |
Enzyme Deficiency: Causes, Consequences & Root CausesExplore the root causes of digestive enzyme deficiency, from pancreatic dysfunction to stress and nutrient depletion, and the systemic consequences of impaired enzyme output. |
Pancreatic vs. Brush Border Enzymes: How Digestion Really WorksLearn the difference between pancreatic enzymes and brush border enzymes, and why both are essential for complete macronutrient digestion and nutrient absorption. |
Category 2: Macronutrient Digestion
Protein Digestion & Proteases: From Stomach Acid to Amino AcidsA deep dive into how proteins are broken down from pepsin activation in the stomach through pancreatic proteases and brush border peptidases in the small intestine. |
Fat Digestion, Bile & Lipases: The Full PictureUnderstand how dietary fats are emulsified by bile, hydrolyzed by lipase, and absorbed as micelles — and what happens when any step in this process breaks down. |
Carbohydrate Digestion & Amylase: From Starch to GlucoseTrace the complete pathway of carbohydrate digestion from salivary amylase through pancreatic amylase and brush border disaccharidases to final glucose absorption. |
Category 3: Nutrient Absorption Mechanisms
The Small Intestine as Absorption Hub: Villi, Microvilli & TransportersExplore the anatomy and physiology of the small intestine as the primary site of nutrient absorption, and how villous damage and transporter dysfunction drive malabsorption. |
Fat-Soluble Vitamins A, D, E & K: Absorption, Transport & DeficiencyLearn how fat-soluble vitamins depend on bile and healthy intestinal function for absorption, and why deficiency in these nutrients is a hallmark of digestive dysfunction. |
Mineral Absorption: Iron, Zinc, Magnesium & CalciumUnderstand the mechanisms of mineral absorption in the gut, the cofactors required, and the digestive root causes of the most common mineral deficiencies. |
Category 4: Conditions That Impair Absorption
Leaky Gut & Malabsorption: The Root Cause ConnectionExplore how intestinal permeability disrupts nutrient absorption, drives systemic inflammation, and creates the conditions for chronic nutrient deficiency and immune dysregulation. |
Exocrine Pancreatic Insufficiency (EPI): Root Causes & Integrative SupportA comprehensive look at EPI — the failure of the pancreas to produce adequate digestive enzymes — its root causes, diagnostic markers, and integrative treatment strategies. |
SIBO & Enzyme Disruption: How Bacterial Overgrowth Impairs DigestionUnderstand how small intestinal bacterial overgrowth competes for nutrients, deconjugates bile acids, and disrupts the enzyme environment of the small intestine. |
Celiac Disease & Villous Atrophy: Malabsorption at the RootExplore how gluten-triggered immune destruction of intestinal villi eliminates absorptive surface area and drives the wide-ranging nutrient deficiencies of celiac disease. |
Category 5: Enzyme Support & Optimization
Digestive Enzymes: When and Why to SupplementA practical guide to digestive enzyme supplementation — who needs it, which enzymes to look for, and how to use them as part of a root cause digestive protocol. |
HCl & Stomach Acid: The Foundation of Digestive Enzyme ActivationDiscover how stomach acid activates the entire digestive enzyme cascade, what happens when HCl is low, and root cause strategies to restore optimal gastric acid production. |
Bitter Herbs & Digestive Bitters: Stimulating Your Body's Own Enzyme ProductionLearn how bitter herbs and digestive bitters stimulate stomach acid, bile, and pancreatic enzyme secretion through the vagus nerve and bitter taste receptors. |
Fermented Foods & Enzyme-Rich Foods: Nature's Digestive AlliesExplore how fermented and enzyme-rich foods like kefir, kimchi, raw honey, and papaya support digestion, enzyme activity, and gut microbiome health. |
Category 6: Systemic Connections
The Gut-Liver Axis & Bile: How Your Liver Drives Digestive Enzyme FunctionDiscover how the gut-liver axis and bile production regulate fat digestion, enzyme activation, and nutrient absorption — and what happens when this system breaks down. |
Nutrient Deficiency Patterns & Root Causes: What Malabsorption Looks Like SystemicallyLearn how digestive enzyme insufficiency and malabsorption create systemic nutrient deficiency patterns — and how to identify and address the root causes. |
Aging & Declining Enzyme Production: Why Digestion Changes as You Get OlderUnderstand why digestive enzyme production declines with age, how this drives nutrient deficiency and chronic disease, and root cause strategies to support digestion as you age. |
