Overview
Digestive enzyme supplements contain proteases, amylases, and lipases that assist in the breakdown of macronutrients. They are particularly useful for individuals with pancreatic insufficiency or age-related enzyme decline.
Mechanism & Function
Pale beige enzyme blend (protease, amylase, lipase). Activity measured in units, not mg.
- Capsule
- Tablet
- Powder
Capsule is generally preferred for bioavailability or efficacy.
Mechanism of Action
Proteases cleave peptide bonds in proteins, amylases hydrolyze starch into maltose, and lipases break triglycerides into fatty acids and glycerol in the small intestine lumen.
Physiological Role
Supplement declining endogenous enzyme production that occurs with aging, stress, and certain medical conditions. Facilitate complete macronutrient digestion and reduce undigested food reaching the colon.
Primary Pathways
Performance / Health Relevance
Athletes consuming high-protein diets may benefit from enhanced protein digestion and reduced GI distress during high-calorie phases.
Evidence Review
Practical Use & Dosage
- Minimum Effective Dose
- Varies by enzyme activity units
- Optimal Range
- Full-spectrum complex with meals: 50,000+ USP protease, 25,000+ USP amylase, 5,000+ USP lipase
- Upper / Caution Level
- Very high lipase doses may cause GI distress
- Timing
- Immediately before or at the start of each meal
- Best Format
- Delayed-release capsules (acid-resistant)
- Bioavailability
- Must survive gastric acid to function in the duodenum. Enteric or delayed-release coatings are preferred.
- Absorption Considerations
- Enzymes are not absorbed — they act locally in the GI lumen. Effectiveness depends on pH-appropriate activity.
Safety & Interactions
Side Effects
- •Mild nausea (rare)
- •Diarrhea at very high doses
Contraindications
- Acute pancreatitis
Drug Interactions
- •Acarbose (alpha-glucosidase inhibitor)
Who Should Avoid
- •Those with pork allergy (for pancreatin-derived enzymes)
Monitoring
No monitoring needed for OTC enzyme supplements.

Psyllium Husk
88/100Psyllium is composed of highly branched arabinoxylan that hydrates into a viscous gel in the small intestine. Unlike most viscous fibres it is only partially fermented in the colon, retaining water-holding capacity throughout the GI tract.
Saccharomyces boulardii CNCM I-745
85/100Saccharomyces cerevisiae var. boulardii strain CNCM I-745 is a transient yeast that survives gastric transit, reaches steady-state colonic concentrations within 3 days, and is cleared 3–5 days after stopping. It works via secreted proteases, anti-inflammatory signalling, and pathogen binding rather than colonisation.
