Overview
Clinical Summary
Digestive-enzyme blends may help some meal-related bloating, indigestion, or functional-dyspepsia symptoms, but direct human evidence for over-the-counter products is still limited and product specific.
Digestive enzymes are easy to overmarket because prescription pancreatic enzymes clearly work in pancreatic insufficiency, while most over-the-counter blends do not have that level of evidence behind them. For general consumers, the real evidence is thinner and more product specific. Some papaya-enzyme-style preparations may improve bloating or constipation symptoms, and a newer randomized trial found benefit for one fungal multi-enzyme blend in functional dyspepsia. That is supportive, but it still does not prove that generic digestive-enzyme blends correct digestion broadly.
Digestive enzymes can theoretically improve breakdown of macronutrients, but outside clear deficiency states the human evidence for OTC blends is limited and highly product specific.
Outcomes
What This Is Expected To Influence

Safety
Contraindications and Interactions
Contraindications
- Unexplained chronic abdominal pain, weight loss, GI bleeding, or severe persistent symptoms
Side effects
- GI irritation
Interactions
No entries provided
Avoid if
- You are using enzymes instead of evaluating persistent GI symptoms

de-SRC-001Randomized controlled trial
Sourceopen_in_newMuss C, Mosgoeller W, Endler T. Papaya preparation (Caricol) in digestive disorders. Neuro Endocrinol Lett. 2013;34(1):38-46. PMID:23524622.
Population: Volunteers with chronic indigestion and gastrointestinal dysfunction symptoms.
Dose protocol: Caricol papaya preparation 20 mL daily for 40 days
Key findings: Improved constipation and bloating versus placebo.
Notes: Supportive digestion-product trial, but not a generic enzyme-blend proof study.
Paper content
This is one of the more relevant human digestion trials for papaya-enzyme-style products. It suggests improvement in constipation and bloating, but the intervention was a papaya preparation rather than isolated papain or a standard digestive-enzyme blend. That makes it supportive but not decisive evidence for enzyme supplements broadly.

Biomed Pharmacother. 2023;169:115858. doi:10.1016/j.biopha.2023.115858. PMID:37976892.
Population: Adults with functional dyspepsia.
Dose protocol: Two capsules daily of a fungal-fermentation multi-enzyme blend for 2 months
Key findings: Improved dyspepsia quality-of-life scores, pain, and sleep without reported side effects.
Notes: Best modern OTC multi-enzyme trial, but still formulation specific and limited to functional dyspepsia.
Paper content
This is the strongest modern OTC digestive-enzyme trial in the batch. In functional dyspepsia, a multi-enzyme blend improved dyspepsia quality-of-life scores, pain, and sleep quality over 2 months versus placebo without reported side effects. The result is still product specific and does not justify broad claims for every enzyme blend or unexplained GI complaint.
