Digestive enzyme supplements may help relieve bloating, gas, and abdominal pain in people with conditions like irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD), according to recent research. These supplements work by breaking down proteins, fats, and carbohydrates so your body can actually absorb the nutrients in food, a process that naturally declines as you get older.

What Are Digestive Enzymes and Why Do They Matter?

Your pancreas naturally produces digestive enzymes that break down the foods you eat into nutrients your body can use. The main types include amylase, which breaks down carbohydrates; lipase, which breaks down fats; and protease, which breaks down proteins. Most people produce enough of these enzymes to digest food properly, but some individuals have a deficiency, meaning their body doesn't produce adequate amounts.

Conditions like pancreatic cancer, chronic pancreatitis, cystic fibrosis, celiac disease, and certain genetic mutations can all lead to digestive enzyme deficiency. In these cases, healthcare providers may prescribe enzyme replacement therapy. However, digestive enzyme supplements are also being studied for people who don't have a true deficiency but experience digestive symptoms like bloating and gas after eating.

What Does the Research Show About Enzyme Supplements?

While research on digestive enzyme supplements for healthy individuals is limited, studies suggest they may help people with specific digestive conditions. A 2017 study found that people with IBD who took a combination of soluble fiber, inositol, and digestive enzymes alongside the medication mesalamine for four weeks reported greater reductions in bloating, gas, and abdominal pain compared to those who received mesalamine alone.

More recent research from 2026 showed that a specialized digestive enzyme blend helped reduce bloating, gas, pain, constipation, and diarrhea in people with IBS. Additionally, a 2020 study involving 50 older adults with dyspepsia, the medical term for indigestion symptoms, found that taking a combination of digestive enzymes and the probiotic Bacillus coagulans for five days led to greater improvements in bloating, gas, and abdominal pain compared to a placebo.

Who May Benefit From Digestive Enzyme Supplements?

Digestive enzyme supplements may be helpful for several groups of people, even without a true enzyme deficiency. Research suggests potential benefits for those experiencing specific digestive challenges or conditions.

• IBS and IBD Sufferers: People with irritable bowel syndrome or inflammatory bowel disease who experience bloating and gas after eating may find relief with enzyme supplements alongside their regular treatment.
• Older Adults: Aging leads to a natural decline in the body's enzyme production, which can contribute to indigestion and other digestive symptoms, making supplementation potentially beneficial.
• People with Dyspepsia: Those experiencing indigestion symptoms including a feeling of fullness during meals, bloating, uncomfortable post-meal fullness, and upper abdominal pain may benefit from enzyme support.
• Non-Celiac Gluten Intolerance: Some research suggests digestive enzymes may offer supplemental support for people with gluten sensitivity who don't have celiac disease.
• Histamine Intolerance: Specific enzymes like diamine oxidase (DAO) may help people who develop symptoms like bloating and headaches after eating high-histamine foods.
• Food Sensitivities: People with lactose intolerance or sensitivity to other foods may benefit from targeted enzyme supplementation.

How to Choose and Use Digestive Enzyme Supplements

• Look for Full-Spectrum Formulas: Choose a product that includes a broad range of enzymes such as protease, lipase, amylase, cellulase, and lactase to support digestion of different nutrients.
• Check Individual Enzyme Potency: High-quality supplements should list the potency of each individual enzyme, not just the total enzyme content, so you know exactly what you're getting.
• Consult Your Healthcare Provider: Before starting any enzyme supplement, especially if you're pregnant, nursing, taking medications, or have a medical condition, discuss it with your doctor to ensure it's appropriate for your specific health needs.
• Consider Your Specific Symptoms: If you regularly experience bloating after high-carb meals, you might benefit from amylase; if nausea follows fatty foods, lipase may help; if beans cause gas, alpha-galactosidase could be useful.

The key takeaway is that digestive enzyme supplements aren't a one-size-fits-all solution. They appear most beneficial for people with specific digestive conditions or those experiencing age-related declines in enzyme production. If you're considering supplementation, the most important step is having a conversation with your healthcare provider about whether it makes sense for your individual situation.
