What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Digestive Enzymes is an enzyme most often used for improved digestion, reduced bloating, nutrient absorption. NutriStack rates the overall evidence as moderate. A typical adult dose is 1-2 capsules with meals, commonly taken as full-spectrum enzyme blend with protease, lipase, amylase, and specialty enzymes. This profile indexes 17 sources.
The bottom line
Evidence rating moderate. Most-documented uses: improved digestion, reduced bloating, nutrient absorption. 17 sources indexed (2014–2024), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Protease cleaves peptide bonds in proteins. Lipase hydrolyzes triglycerides into fatty acids and glycerol. Amylase breaks starch into maltose and glucose. Cellulase/hemicellulase break down plant fiber. Lactase cleaves lactose into glucose and galactose.15,2
Dosing & protocol.
What it actually costs.
Real-world pricing across three quality tiers. Assumes Full-Spectrum Enzyme Blend.
Assumes 1-2 capsules with meals. Vendor basis: NOW/iHerb, Vitacost, Thorne, and Amazon marketplace; specialty enzyme activity blends set premium pricing. Updated 2026-05-28.
The same dose, as food.
How much you'd eat to match a supplemental dose.
Food enzyme activity is much less standardized than capsule blends and may not replace medically needed enzymes.
