Evidence-Based Benefits

  • Pancreatic insufficiency — PERT is standard of care for EPI; Dominguez-Munoz (2011) reviewed that adequate lipase supplementation normalizes fat absorption and eliminates steatorrhea
  • Lactose intolerance — exogenous lactase (e.g., Lactaid) effectively prevents symptoms when taken with dairy; de Vrese et al. (2001, n=18) confirmed symptom reduction
  • Functional dyspepsia — Suarez et al. (1999) found alpha-galactosidase significantly reduced flatulence from high-fiber meals containing raffinose and stachyose
  • Bloating reduction — a 2018 RCT (Quinten et al., n=40) found a multi-enzyme supplement reduced post-meal bloating and fullness in healthy adults eating a high-calorie meal

What the Research Says

Digestive enzymes have a clear role in pancreatic exocrine insufficiency, where PERT is standard of care. For targeted food intolerances (lactase for lactose, alpha-galactosidase for legume sugars), single-enzyme products are well-supported. The evidence for OTC broad-spectrum enzymes in functional dyspepsia is emerging but growing. A key limitation is that many OTC products do not undergo the same rigorous testing as prescription PERT products.
