📰Read the full Digestive Enzymes evidence review on GMJ News →Complete clinical article, references and updates on news.gmj.ge. This page is the structured safety summary.⚠ Patient with steatorrhea + weight loss — test for PEI (fecal elastase); may need Creon [1]
⚠ Patient on acarbose + amylase supplement — enzyme counteracts the drug [1]
⚠ Most OTC enzymes lack enteric coating — may be degraded by stomach acid [1]
⚠ Lactase for lactose intolerance: well-evidenced specific use [1]
ℹ️ Not obtained from food. Not applicable — this is not obtained from food in meaningful amounts; supplementation is the practical route.

>200 µg/g (normal)
<200 = PEI. <100 = severe PEI [1].

Clinical verdict
Digestive enzymes have ONE clear medical indication: PEI (Creon for CF, chronic pancreatitis, post-Whipple). Lactase for lactose intolerance and Beano for bean gas are specific, well-evidenced uses. OTC 'general enzyme' supplements for healthy people have limited evidence — most bloating is not enzyme deficiency [1] [2].
1 How much do I need?
👤 Adults: Specific dosage data under clinical review
👴 Elderly: Specific dosage data under clinical review
🤰 Pregnancy: See guidance
PERT used in CF pregnancy. OTC: limited data [1].
👦 Pediatric: See guidance
PERT is used in children with CF from infancy [1].
🏃 Athletes: Standard dose
⚖️ Obesity: Standard dose
Fat-soluble compounds may require dose adjustment in obesity.
🩺 Renal: Consult specialist
Dose adjustment may be needed in renal impairment.
🌱 Vegan: Standard dose
How to take
🍽 Timing: With meals (immediately before or with first bite) [1].
💊 With food: WITH food — enzymes need substrate [1].
🚫 Avoid: Acarbose patients: don't add amylase [1].
2 Which form?
| Form | Bioavailability | Vegan | Cost |
|---|---|---|---|
| ['PERT (Creon, Zenpep)', 'preferred', 'Prescription porcine pancreatic enzymes. For PEI (CF, chronic pancreatitis, post-Whipple). Enteric-coated. Dosed per fat intake [1].'] | Standard | Check label | |
| ['OTC broad-spectrum enzymes', 'common', 'Fungal/plant-derived. Variable potency. Not standardized [2].'] | Standard | Check label | |
| ['Lactase (Lactaid)', '', 'Specific for lactose intolerance. Well-evidenced [1].'] | Standard | Check label | |
| ['Alpha-galactosidase (Beano)', '', 'Specific for oligosaccharide gas (beans) [1].'] | Standard | Check label |
3 Common questions
Do I need digestive enzymes if I'm healthy? ▼
Probably not. Healthy individuals produce adequate digestive enzymes. OTC enzyme products are heavily marketed for 'bloating' and 'heaviness,' but evidence for benefit in enzyme-sufficient individuals is limited [2]. Specific exceptions: lactase for lactose intolerance, alpha-galactosidase for bean gas [1].
What is PEI? ▼
Pancreatic Exocrine Insufficiency — the pancreas doesn't produce enough digestive enzymes. Causes: cystic fibrosis, chronic pancreatitis, pancreatic cancer, post-Whipple surgery. Requires prescription PERT (Creon) [1]. This is the REAL indication for digestive enzymes.
Can enzymes help IBS? ▼
Possibly — one trial found pancreatic enzymes helped IBS-D patients, suggesting a subclinical PEI subset exists within IBS. Not standard therapy [2].
Do enzymes survive stomach acid? ▼
Prescription PERT is enteric-coated to survive acid. Many OTC products are NOT enteric-coated — acid may degrade enzymes before they reach the duodenum where they're needed [1].
4 Clinical evidence
Strong
PERT for PEI (cystic fibrosis, chronic pancreatitis, post-Whipple): essential, life-saving treatment. Reduces steatorrhea and malabsorption [1]. Lactase for lactose intolerance: well-established [1]. Alpha-galactosidase for bean gas: effective [1]. HIGH
Moderate
IBS: one trial of pancreatic enzymes showed benefit in IBS-D (possible subclinical PEI subset) [2]. Functional dyspepsia: some evidence for combination enzyme products [2]. MODERATE
Insufficient
5 Safety, toxicity & adverse events
Absolute contraindications
✕ Early/acute pancreatitis
✕ Known hypersensitivity to porcine protein (for pancreatin products)
Relative
⚠ Peptic ulcer disease — protease activity
⚠ Gout — some products add purine load
⚠ Concurrent acarbose/antidiabetics — may alter carbohydrate handling
🚩 Red flags
● CF patient on very high-dose PERT — fibrosing colonopathy risk [1]
● Patient on acarbose + digestive enzyme supplement [1]
6 Interactions
Drug interactions
Acarbose/miglitol Major
Mechanism: Amylase supplements reverse acarbose's mechanism of action. [1]
Effect: Negated blood glucose lowering. [1]
Action: Avoid amylase-containing enzymes with acarbose [1].
