What the science says

Exocrine pancreatic insufficiency Strong evidence
A systematic review and meta-analysis found pancreatic enzyme replacement improves the coefficient of fat absorption and nutritional status in exocrine pancreatic insufficiency. It is backed by double-blind placebo-controlled trials, including in chronic pancreatitis.
Dose and formulation matter Moderate evidence
A systematic literature review of treatments for exocrine pancreatic insufficiency found efficacy depends on enteric-coated preparations and adequate lipase units taken with meals. Low-dose, uncoated OTC supplements are unlikely to reproduce those results.
Healthy people after heavy meals Limited evidence
No trial has shown that pancreatin improves digestion, bloating or comfort in people with normal pancreatic function. This is the most common reason it is bought and the least supported.

Dosage & safety

Studied doseIn pancreatic insufficiency, 40,000–50,000 lipase units with main meals and about half that with snacks, in enteric-coated form. OTC supplements typically supply a small fraction of this.

SafetyGenerally safe; very high doses have been linked to fibrosing colonopathy in children with cystic fibrosis. It is derived from porcine pancreas, so unsuitable for some diets and capable of causing allergic reactions. Persistent fatty, floating stools with weight loss need a diagnosis, not a supplement.
