One of the fastest-growing supplement categories today is digestive enzyme supplements, which help the body break down food more efficiently and ease feelings such as occasional heartburn, bloating, gas, cramping, heaviness, and discomfort after eating.
With nearly 70 million Americans 1,2 experiencing gastrointestinal issues, it’s no surprise that digestive enzyme supplements are flooding the marketplace, but many fall short. The problem?
Many big-name brands only include a handful of enzymes in their formulas, nowhere near enough to provide real relief. You keep spending your hard-earned money on digestive supplements, yet you’re still struggling with discomfort after every meal.
With so many digestive enzymes available, determining which ones actually work can be tough. That’s why we’ve done the research to determine the types and amounts of effective enzymes shown to help ease gas, bloating, occasional indigestion, constipation, and diarrhea after meals.
This short guide will help you identify what to look for and what to avoid, so you can make an informed decision about your digestive needs. We will also list out the top 5 digestive enzyme supplements sold today.
Let’s take a moment to understand precisely how digestive enzymes work and why adding them to your daily routine is essential.
Your digestive system operates as a remarkable chemical factory, powered by digestive enzymes. When you eat, your body can’t immediately absorb whole foods in their original form.
That’s where enzymes come in. Think of them as specialized molecular scissors, each one precisely designed to break down specific nutrients. Some target fats, others tackle proteins, while different enzymes handle carbohydrates and fibers, transforming them all into smaller molecules your body can actually use.
Without adequate enzymes, even the most nutritious meals can cause problems. Food sits undigested in your gut, leading to that uncomfortable, bloated feeling instead of the energy and nourishment you should be getting from your food. 3,4
If foods you used to eat without a second thought now leave you feeling bloated, heavy, or uncomfortable—you’re not imagining it.
Here’s what’s happening: Your pancreas, the organ that produces digestive enzymes to break down food, naturally slows down with age. As early as your 40s, enzyme production begins to decline. 5,6
With fewer enzymes, your body can’t break down food as efficiently. Proteins sit longer in your stomach. Fats take longer to process. Even healthy carbs can cause issues.
The result? That sluggish, bloated feeling after meals. Foods that never bothered you suddenly become problematic. You may even be losing vital nutrients because your body can’t properly absorb what you’re eating.
The good news? Quality digestive enzyme supplements can support your body’s declining enzyme production.
Most digestive enzyme products only contain a handful of enzymes, typically just 3 to 5, which is nowhere near enough to properly break down the complex variety of foods you eat daily.
Our research shows that truly effective digestive enzyme formulas must include a complete spectrum of specific enzymes, each targeting different nutrients; otherwise, you’re only getting partial support and are likely still dealing with digestive discomfort.
Here are the essential enzymes every quality supplement should include:
1. Amylase
Breaks down starches and complex carbohydrates from foods like bread, pasta, potatoes, and rice into simple sugars your body can absorb and convert into energy.
2. Cellulase
Breaks down tough plant fibers from fruits, vegetables, and whole grains, helping you extract more nutrients while reducing the gas and bloating that high-fiber foods can cause.
3. Lactase
Breaks down lactose, the sugar found in milk and dairy products such as cheese, yogurt, and ice cream, easing the discomfort associated with lactose intolerance.
4. Lipase
Breaks down dietary fats from foods like avocados, nuts, oils, butter, and meats into absorbable fatty acids, helping your body utilize fat-soluble vitamins and essential nutrients.
5. Papain
Breaks down starches and complex carbohydrates from foods like bread, pasta, potatoes, and rice into simple sugars your body can absorb and convert into energy.
6. Protease
Breaks down starches and complex carbohydrates from foods like bread, pasta, potatoes, and rice into simple sugars your body can absorb and convert into energy.
Ease occasional indigestion and heartburn 10
If a supplement only lists a handful of enzymes, walk away. This is the biggest red flag in the industry. Here’s why: Your body needs multiple specialized enzymes to break down the variety of foods you eat. Proteins require different enzymes than fats. Carbohydrates need their own set. Dairy, fiber, and starches each require specific enzymes to be digested properly. 13,14 A quality digestive enzyme formula should contain at a minimum 15 different enzymes working together to handle the full spectrum of nutrients in your meals. Anything less means you’re getting incomplete digestive support and likely still experiencing discomfort after
Look at the “Supplement Facts” panel on the label. Each enzyme (amylase, lipase, protease, cellulase, lactase, etc.) will be listed separately. Count them up. If you don’t see at least 15, that product won’t give you the comprehensive support your digestion needs.
After reviewing dozens of digestive enzyme supplements, we discovered a disturbing trend: many brands don’t disclose the actual strength of their enzymes.
Enzyme effectiveness isn’t measured by weight (milligrams), but by activity units, which tell you how much digestive work each enzyme can perform. When brands omit these units, they’re hiding whether their enzymes are actually potent enough to work. It’s like buying a car without knowing the horsepower.
Look at the “Supplement Facts” panel. Reputable brands list specific activity units in parentheses next to each enzyme (HUT, DU, FCC PU, or SAPU.) If these aren’t shown, the manufacturer is likely using weak, ineffective doses. Avoid those products.
Avoid digestive enzyme supplements that contain only enzymes and nothing else. This is a sign of a bare-bones, incomplete formula.
Quality digestive support requires more than enzymes alone. Without coenzymes like vitamin K1 and zinc to enhance enzyme function and vegetable-based antioxidants and phytonutrients to support gut health, your body can’t break down and absorb nutrients as effectively or comfortably. 15-17
Budget brands skip these supporting ingredients to cut costs, leaving you with a one-dimensional product that only addresses part of the problem.
Any supplement that lists only digestive enzymes on the label with no additional supporting ingredients like coenzymes or vegetable blends. A comprehensive digestive supplement should support your entire digestive system, not just one piece of it.
After months of researching dozens of digestive enzyme formulas, we’ve identified the key factors separating high-quality digestive enzymes from the rest. The best digestive enzyme products contain four essential ingredients directly impacting how well and quickly they work. Use these criteria as your checklist when evaluating any digestive enzyme supplement to ensure you’re getting a formula worth your money and a brand that suits your needs.

Stonehenge Health® Dynamic Digestive Enzymes is Review Scout’s top-rated choice. This comprehensive formula features all four essential components of an effective digestive enzyme supplement: a multi-enzyme blend containing 18 high-potency enzymes that target different nutrients for complete digestion, the dairy-digesting enzyme lactase, coenzymes Vitamin K1 and Zinc to enhance nutrient breakdown, and the PhytoServ® Veggie Blend for added plant-based support.
After reviewing dozens of digestive enzyme formulas, we found that most lack broad-spectrum enzyme support, making Stonehenge Health one of the few brands offering such an extensive 18-enzyme profile. The formula stands out by incorporating the research-backed BioCore® Optimum Complete blend, a patented combination of enzymes that target proteins, fats, carbohydrates, dairy, and fiber to support efficient digestion starting in the upper stomach.
Beyond enzymes, this formula provides a potent source of natural antioxidants and phytonutrients, equivalent to one whole serving of vegetables, along with essential nutrients like Vitamin K1 and Zinc.

Multienzyme Formula
Includes Lactase
High Potency Enzymes
Manufactured in the USA
Non-GMO, Gluten & Soy-Free, Vegan, No artificial ingredients
Includes Only 13 Enzymes
No Added Veggie Blend
Limited Return Policy
Enzymedica Digest Gold + ATPro includes three of the four essential components of an effective digestive enzyme supplement. It features a multi-enzyme formula containing 13 enzymes along with lactase and a key coenzyme to support digestive health. While this is a solid formula, it offers significantly fewer enzymes than the top-rated brand, which provides 18. For that reason, we don’t love seeing customers pay a similar price for nearly half the enzyme diversity.
We do appreciate that Enzymedica enhanced their formula with ATPro™, a specialized nutrient complex that combines ATP (adenosine triphosphate), magnesium citrate, phytase, and Coenzyme Q10. This addition supports not only digestion but also the cellular energy and nutrient absorption processes that follow. However, we would have liked to see the inclusion of a veggie blend for added phytonutrient support.
One area of concern is the return policy. Enzymedica only accepts returns of new, unopened products within 30 days of delivery for a full refund, which is considerably more restrictive than competitors’ offerings, which typically include longer, satisfaction-based guarantees.

Pure Encapsulations Digestive Enzymes Ultra includes two of the three essential digestive enzyme components. It’s a multi-enzyme formula featuring lactase and a blend of 13 enzymes that support the breakdown of proteins, fats, carbohydrates, and fiber. While we appreciate its broad enzyme coverage, it falls short of the top-rated brand, which offers 18 enzymes for more complete digestive support.
This formula also lacks additional supporting ingredients such as coenzymes or plant-based phytonutrients that could enhance its overall effectiveness. Because it relies solely on enzymes, we consider it somewhat limited compared to more comprehensive digestive support blends.
Another drawback is the restrictive return policy. Refund eligibility depends on the specific retailer, and on Amazon, the product is listed as non-returnable.

Made In The USA
Includes Only 10 Enzymes
No Lactase
No Coenzymes
No Added Veggie Blend
Zenwise Digestive Enzymes contains only one of the essential digestive enzyme components. While it is a multi-enzyme formula, it includes just 10 enzymes in total. The formula also lacks supporting ingredients such as coenzymes and plant-based blends that could further enhance digestive health.
This product ranks lower on our list due to its lack of transparency. The label does not specify enzyme activity units, making it impossible to determine the actual strength or potency of each enzyme in the formula.
While we appreciate the brand’s hassle-free, no-questions-asked return policy, the lack of a clearly stated return window is a significant drawback that leaves customers uncertain about how long they have to evaluate the product’s effectiveness.

Despite being one of the more expensive digestive enzyme supplements on the market, Thorne Advanced Digestive Enzymes falls short on several critical criteria. The most significant issue is the limited diversity of enzymes. The formula relies heavily on pancreatin (porcine), which provides only three basic enzymes: amylase, protease, and lipase. Adding pepsin (porcine) doesn’t meaningfully expand the profile. This falls far below the 15-enzyme minimum we recommend for comprehensive digestive support.
Notably absent is lactase, the enzyme essential for digesting dairy products. Given that approximately one-third of adults struggle with lactose, this is a significant oversight at this price point.
Another red flag is that Thorne doesn’t list enzyme activity units. Without measurements like HUT, DU, or FCC units, there’s no way to verify actual potency or compare effectiveness against competitors. This lack of transparency is concerning. Using pancreatin and papaya fruit powder instead of isolated, standardized enzymes suggests a less sophisticated formulation than top-rated brands.
Finally, Thorne’s 60-day return window is shorter than the 90-day return windows that leading brands typically offer.
