Do Digestive Enzyme Supplements Actually Work for Bloating? Gastroenterologists Weigh In
Gastroenterologists say most healthy people do not need digestive enzymes. Here is what to know before you buy.
If you deal with recurring bloating, gas or post-meal discomfort, you have probably wondered whether an over-the-counter enzyme pill could quietly fix the problem. Here is what the research and gastroenterologists actually say.
What are digestive enzymes and how do they work?
Digestive enzymes are proteins that break food into nutrients your body can absorb, and different enzymes target different macronutrients. Digestion starts in the mouth and continues through the stomach and small intestine.
“The digestive enzymes naturally occurring in the body break down our food so that we can absorb the nutrients required for our bodily functions,” Dr. Caroline Tuck, a dietitian and senior lecturer in dietetics at Swinburne University of Technology in Melbourne, Australia, told CNN.
The five main types are amylase (carbohydrates), lactase (milk sugar), lipase (fats), protease (proteins) and sucrase (sugar in fruits and nuts).
When is the best time to take digestive enzymes?
Take them within the first few bites of a meal. The capsules only work in direct contact with food, so swallowing them on an empty stomach offers almost no benefit.
“You want the enzymes to be mixed in with the food as digestion begins,” Dr. Rudolph Bedford, a gastroenterologist at Providence Saint John’s Health Center in Santa Monica, California, told Prevention. Lactase is the exception and can be taken right before a specific trigger like a latte or ice cream, according to Bedford.
Do over-the-counter digestive enzyme supplements actually work?
Evidence is strongest for two targeted products, Lactaid (lactase) for lactose intolerance and Beano (alpha-galactosidase) for gas and bloating after legumes. Broader daily debloating claims have limited scientific support, according to major medical sources.
Prescription enzymes are a different story. The FDA regulates them as drugs used primarily for exocrine pancreatic insufficiency, or EPI, when the body does not produce enough enzymes to digest food. FDA-listed products include Creon, Zenpep, Pancreaze, Pertzye, Ultresa and Viokace.
Who actually needs digestive enzyme supplements?
People with diagnosed enzyme deficiencies are the primary group with a real clinical need, according to Dr. Deborah Cohen, associate professor in the department of clinical and preventive nutrition sciences at Rutgers University. Warning signs include diarrhea, stomach pain and bloating. Other red flags are unexplained weight loss and fatty or oily stool that floats.
Those patients are “really the only people with a clinical or legitimate need for digestive enzyme products,” Cohen told CNN. Healthy people who occasionally overeat do not need a pill, though heavy meals may take longer to digest and cause some bloating.
“If you take them anyway, most of the danger lies in the possible waste of your money,” Cohen said. If you are using enzymes to manage recurring symptoms, see a gastroenterologist. You may be masking a problem that needs supervised treatment.
How big is the digestive enzyme supplement market in 2026?
The global market hit $1.5 billion in 2024 and is projected to reach $2.1 billion by 2030, according to Grand View Research. An estimated 70 million Americans have digestive issues, fueling demand for quick fixes.
Key players include HUM Nutrition’s Flatter Me, Arrae’s Bloat and MaryRuth’s Ultra Digestive Enzymes. Physician’s Choice sells a formula combining enzymes with probiotics, prebiotics and herbs at Target, and NBPure is expanding into Target in 2026.
Which foods naturally contain digestive enzymes?
Papaya, kiwi, mango, avocado, figs and pineapple all naturally contain digestive enzymes. Eating them is a common starting point for people trying to support digestion through diet before turning to capsules.
But whole foods are not a substitute if you actually have a deficiency. Food-based enzymes are often broken down before they can meaningfully support digestion, according to Bedford. If you are dealing with persistent symptoms, a gastroenterologist should be the first stop, not the supplement aisle.
