Does digestive enzymes help with inflammation? What the research does and doesn't show

The evidence doesn't support digestive enzyme supplements, including DigeZyme, as a way to reduce inflammation. No trial has tested DigeZyme's blend of alpha-amylase, protease, lipase, cellulase and lactase against an inflammatory marker or a diagnosed inflammatory condition. The closest research uses an entirely different enzyme category, dosed and taken differently, for a different purpose.

What the evidence doesn't support

It doesn't support DigeZyme, or any over-the-counter digestive-enzyme blend, as something that lowers inflammation or treats a diagnosed inflammatory condition like arthritis or inflammatory bowel disease. DigeZyme's five enzymes are digestive enzymes, meant to be taken with food to help break down what's in a meal. The enzyme products that have actually been studied for inflammation are a different category — systemic or proteolytic enzymes, usually bromelain, trypsin and rutin, directed to be taken away from food so more of the enzyme is absorbed into the bloodstream rather than used up digesting a meal. A supplement isn't a substitute for medical management of a diagnosed inflammatory disease.

What the trials found

The one placebo-controlled trial of DigeZyme itself studied 40 adults with functional dyspepsia at 150 mg/day for 60 days and measured symptom questionnaires — not blood markers of inflammation like CRP or cytokines. It doesn't tell us anything about inflammation one way or the other.

The closest inflammation-relevant research uses Wobenzym, a systemic enzyme blend of bromelain, trypsin and rutin — not DigeZyme's digestive enzymes. A 2015 randomized, placebo- and comparator-controlled trial gave 150 adults with moderate-to-severe knee osteoarthritis Wobenzym, the prescription NSAID diclofenac, or placebo, for 12 weeks (the trial also tested a prescription drug, so we're reporting only that it did, not how the two treatments compared to each other). On the primary pain measure, the Wobenzym group improved significantly more than placebo; on a secondary function score, it didn't. The Wobenzym group needed less rescue pain medication than placebo, and reported side effects at a similar rate to placebo. That's a different enzyme blend, at a different dose, taken a different way, tested in diagnosed osteoarthritis — not DigeZyme, and not a direct measure of inflammation itself.

Study	Population & design	Dose / method	Result
2018 RCT (DigeZyme)	40 adults with functional dyspepsia	DigeZyme, 150 mg/day, 60 days	Improved symptom scores vs. placebo; didn't measure inflammation
2015 RCT (Wobenzym)	150 adults with knee osteoarthritis	Systemic enzyme blend (bromelain, trypsin, rutin), 12 weeks	Improved primary pain score vs. placebo; different enzymes and dosing from DigeZyme

Questions people ask

Do digestive enzymes reduce inflammation?

We haven't found a trial testing DigeZyme, or a comparable digestive-enzyme blend, against an inflammatory marker or a diagnosed inflammatory condition. The enzyme research that does exist for inflammation uses a different enzyme category entirely.

What's the difference between digestive enzymes and systemic enzymes for inflammation?

Digestive enzymes like DigeZyme's alpha-amylase, protease, lipase, cellulase and lactase are taken with food to help digest it, and mostly stay in the digestive tract. Products studied for inflammation, like Wobenzym, use different enzymes (bromelain, trypsin, rutin) and are typically directed to be taken away from food, on an empty stomach, so more of the enzyme is absorbed into the bloodstream rather than consumed digesting a meal.

Can digestive enzymes help with joint pain?

No trial has tested DigeZyme, or a similar over-the-counter digestive-enzyme blend, for joint pain. The one enzyme trial in knee osteoarthritis used a different, systemic enzyme product, not a digestive blend.

When to talk to a doctor

Ongoing joint pain, swelling, or other signs of a diagnosed inflammatory condition are worth raising with a doctor rather than addressing with a digestive-enzyme supplement, which is not a treatment for inflammation. See digestive enzymes: what the research does and doesn't show for the broader research picture, and digestive enzymes and GI disease for enzyme research in other diagnosed conditions.
