Best Digestive Enzyme Supplements in 2026: What the Evidence Says
By SupplementList Editorial Team • 2026-05-03
Digestive enzyme supplements contain concentrated enzymes that help break down proteins, fats, and carbohydrates. They are used for bloating, gas, food intolerances, and conditions that impair enzyme production. An estimated 15–20% of adults experience functional digestive symptoms that may respond to enzyme support (Ford et al., 2014).

How Digestive Enzymes Work
The body naturally produces digestive enzymes in the salivary glands, stomach, pancreas, and small intestine. When enzyme production is insufficient — due to pancreatic insufficiency, aging, low stomach acid, or food sensitivities — undigested food reaches the large intestine, where bacteria ferment it, causing gas and bloating. Supplemental enzymes provide exogenous support to fill these gaps.
Key Enzyme Classes
Protease / Bromelain / Papain: Break down proteins. Bromelain (from pineapple) and papain (from papaya) are plant-derived and well-tolerated. Lipase: Breaks down dietary fats — important for those with gallbladder removal or high-fat diets. Amylase: Breaks down starches. Lactase: Breaks down lactose — highly effective for lactose intolerance when taken with dairy. Alpha-galactosidase: Breaks down oligosaccharides in legumes and cruciferous vegetables (e.g., Beano). Betaine HCl: Not an enzyme but supports stomach acid for protein pre-digestion.
Who Benefits Most
The clearest evidence supports enzyme supplements for: lactose intolerance (lactase), exocrine pancreatic insufficiency (pancrelipase), IBS with bloating, and alpha-galactosidase for legume or cruciferous vegetable digestion. A 2019 meta-analysis in Nutrients found enzyme supplementation reduced bloating and gas in IBS patients versus placebo (Lacy et al., 2019).
