Digestive Enzymes
Also known as: proteases, lipases, amylases, microbial enzymes, pancreatic enzymes, bromelain, papain
Effective Dosage
No established dose from provided studies
What the Science Says
Digestive enzymes are proteins that break down food — proteases split proteins, lipases break down fats, and amylases digest carbohydrates. One randomized clinical trial found that co-ingesting a microbial protease blend with whey protein increased early post-meal essential amino acid levels by about 14% and branched-chain amino acids by 15% compared to placebo, while also reducing hunger hormone ghrelin. A separate multi-ingredient GI supplement study reported self-reported improvements in digestive comfort over 14 days, though that product contained many other ingredients making it impossible to credit enzymes alone.
What It Doesn't Do
Won't dramatically transform your protein absorption — the amino acid boost seen in studies was modest and short-lived. No evidence from these studies that they help with weight loss. No proof they fix chronic digestive conditions like IBS or Crohn's. The multi-ingredient GI study can't tell us enzymes specifically caused the improvements. Most animal and fish studies here have zero relevance to human supplementation.
Evidence-Based Benefits
Co-ingestion of a microbial protease mixture with whey protein modestly enhanced early postprandial essential amino acid and branched-chain amino acid availability by ~14-15% and reduced ghrelin while increasing satiety signals in healthy adults (PMID: 40675336). A multi-functional GI primer supplement containing digestive enzymes among other ingredients improved self-reported digestive symptoms, stool consistency, and quality-of-life measures over 14 days in participants with mild digestive complaints (PMID: 39339773). However, the evidence base from the provided papers is limited and does not isolate digestive enzymes as standalone interventions in rigorous, large-scale human trials.

Absorption & Bioavailability
Unknown — the provided studies do not directly measure enzyme survival through the GI tract. One nanoparticle study notes that oral proteins face degradation by gastric acid and digestive enzymes, suggesting enzyme supplements themselves may be partially degraded before acting.
Red Flags to Watch For
- Most papers in this dataset involve animals (fish, piglets, insects) — not humans. Don't extrapolate animal findings to human benefits.
- The only positive human RCT tested a specific 3-enzyme protease blend with whey protein — results may not apply to other enzyme products or food sources.
- Multi-ingredient GI supplement study (PMID 39339773) cannot isolate enzyme effects from other ingredients like probiotics or fiber.
- Products with 1000+ registered formulations on NIH DSLD vary wildly in enzyme type, source, and potency — label claims are largely unverified.
- Enzyme inhibitor studies (pine bark, topiramate conjugates) are about blocking enzymes, not supplementing them — don't confuse these with enzyme supplement benefits.
