- What are digestive enzyme supplements? Digestive enzyme supplements contain enzymes such as bromelain, papain, amylase, cellulase and phytase, that can help you digest specific foods when you do not naturally produce enough enzymes. (See "What They Are" for a list of enzymes and the foods they break down.) They may also have other beneficial effects.
- How to choose a digestive enzyme supplement: Choose a digestive enzyme supplement that lists enzyme activity units (such as PU, HUT, FIP, etc.), not just the amount of enzyme (such as milligrams) since that won't tell you how potent the enzyme is (See "What They Do"). Also, check that ConsumerLab.com or another reputable independent 3rd party has verified the enzyme activity. As found in this Review, some products don't provide what they list (See "What CL Found")

- Digestive enzyme supplements safety and side effects: Digestive enzymes are generally well-tolerated but people with allergies to a specific enzyme source, certain medical conditions, or who take medications such as blood-thinners or diabetes drugs may need to avoid specific enzymes (See "Concerns and Cautions").
