💊 What it does
Digestive enzymes are proteins produced naturally by the pancreas, stomach lining, and small intestine to break down food components: proteases break down protein, amylases break down carbohydrates, lipases break down fats, and cellulases break down plant cell walls. Supplement digestive enzyme complexes aim to support or augment this process, particularly for people with reduced digestive capacity, food intolerances, or digestive discomfort after meals. The evidence is strongest for specific enzyme deficiencies (lactase for lactose intolerance, alpha-galactosidase for gas from beans and legumes).
👤 Who needs it
People with exocrine pancreatic insufficiency (EPI) — a medical condition requiring prescribed pancreatic enzyme replacement therapy. Those with age-related decline in digestive enzyme production. People who experience persistent bloating, gas, or discomfort after meals. Those transitioning to a high-fibre plant-based diet who experience temporary digestive adjustment. People with lactose intolerance (lactase supplements). Those who eat significant amounts of legumes and experience gas (alpha-galactosidase — the active ingredient in Beano).
🥦 Food sources first
The body produces all needed digestive enzymes from pancreatic and intestinal sources. A healthy gut with adequate stomach acid, good diet, and diverse microbiome generally produces sufficient enzymes without supplementation. Fermented foods (sauerkraut, kimchi, miso, tempeh) and raw plant foods naturally contain enzymes that support digestion.
🗓 When to supplement
When persistent digestive discomfort, bloating, or food intolerances suggest impaired digestion. As a short-term aid when transitioning to a higher-fibre diet. Specific enzyme supplements (lactase, alpha-galactosidase) have strong evidence for specific intolerances. General digestive enzyme supplements have weaker evidence for healthy individuals.
🏷 Best form to look for
Broad-spectrum plant-derived enzyme complexes (from Aspergillus oryzae) are preferable for vegans over animal-derived pancreatin. For specific applications: lactase for dairy; alpha-galactosidase for legume gas; bromelain (pineapple-derived protease) for protein digestion and anti-inflammatory effects.
⏰ When to take it
Immediately before or at the beginning of a meal — timing is important as enzymes must be present when food arrives in the stomach.
