At a glance
What it is, why people use it, the evidence, and what to know before trying it.
Why people use it
- Digestive comfort
- Support for nutrient digestion
- Replacement of a documented enzyme deficiency
Evidence at a glance
Targeted enzymes can be effective for diagnosed deficiencies such as pancreatic insufficiency or lactose intolerance. Evidence is much weaker for unspecified multi-enzyme capsules taken with ordinary meals by otherwise healthy adults.
Confidence: weak
Safety & interactions
Known side effects, interactions and use limits from reviewed sources.
Risks depend on the ingredients and source. Products may cause gastrointestinal symptoms or allergy, and proteolytic enzymes can interact with anticoagulants. Persistent digestive symptoms need evaluation rather than indefinite self-treatment.
- Unexplained persistent abdominal symptoms without medical evaluation
- Known allergy to animal, fungal or fruit-derived enzymes
- Abdominal discomfort
- Diarrhea or constipation
- Allergic reaction
- Anticoagulants or antiplatelet medicines for some proteolytic enzymes
