You’re sitting there, scrolling through your phone, feeling heavy and bloated, wondering why your gut has decided to go on strike. It’s a literal logjam. You’ve probably tried the usual suspects: a gallon of water, those grainy fiber supplements that taste like sawdust, maybe even a desperate cup of "smooth move" tea. Then you see it—a bottle of digestive enzymes at the health food store promising to "break down food" and "optimize digestion." It sounds logical, right? If you break down the food better, it should move through faster. But do digestive enzymes help with constipation, or are you just flushing money down the toilet?
Honestly, the answer isn't a simple yes or no. It's more of a "maybe, but probably not for the reason you think."
Most people confuse digestive enzymes with probiotics or laxatives. They aren't the same thing at all. While a laxative forces your colon to contract or pulls water into your stool, enzymes are basically biological scissors. Their only job is to snip large molecules of protein, fat, and carbs into tiny pieces so your small intestine can absorb them. If those scissors are sharp, your food gets absorbed. If they're dull, that food sits there, ferments, and causes a whole mess of trouble.
The Real Connection Between Enzymes and Your Bathroom Schedule
To understand if these supplements do anything for your transit time, we have to look at what's actually happening in your gut. Constipation usually happens in the large intestine (the colon). Digestive enzymes, however, do almost all of their work in the stomach and the small intestine. By the time your "waste" reaches the colon, the window for enzyme action has mostly closed.
So, how could they possibly help?
It’s all about the "leftovers." When your pancreas doesn't produce enough enzymes—a condition doctors call Exocrine Pancreatic Insufficiency (EPI)—undigested food particles travel further down the digestive tract than they’re supposed to. This is where things get gross. Bacteria in your large intestine start feasting on those undigested bits. This creates gas, massive bloating, and can actually slow down the wave-like muscle contractions (peristalsis) that move stool along. In this specific scenario, taking a supplement like lipase or amylase might indirectly help because it cleans up the mess before it reaches the "slow zone."
But let's be real: for the average person with occasional backup, enzymes aren't a magic bullet.
When Enzymes Might Actually Be the Answer
There are specific groups of people who will see a massive difference. If you have cystic fibrosis, chronic pancreatitis, or you’ve had gallbladder surgery, your enzyme production is likely compromised. In these cases, doctors often prescribe high-potency enzymes like Creon or Zenpep.
For everyone else, it’s usually about specific food intolerances.
Think about lactose intolerance. If you lack the enzyme lactase, dairy doesn't get broken down. For some, this causes "the runs." But for others? It causes incredible bloating and a total systemic backup. Taking a lactase supplement before a bowl of ice cream won't "cure" constipation, but it prevents the digestive train wreck that leads to it.
The same goes for Alpha-galactosidase. That’s the stuff in Beano. It breaks down the complex sugars in beans and cruciferous veggies like broccoli. If you find that eating healthy, high-fiber foods actually makes your constipation worse—which is a real thing called "fiber-associated bloat"—it might be because you lack the enzymes to handle that specific fiber. In that very narrow context, digestive enzymes help with constipation by making fiber more manageable for your system.
The Different Players: Amylase, Protease, and Lipase
If you look at the back of a bottle of Zenwise or Thorne enzymes, you’ll see a bunch of words ending in "-ase." Each one has a specific target.
- Amylase: Breaks down starches and sugars. If you’re a carb lover who feels like bread sits in your stomach like a brick, this is the one.
- Protease: Breaks down proteins. Essential for those on high-protein diets or anyone who feels "heavy" after eating steak.
- Lipase: Breaks down fats. If you don’t have a gallbladder, you basically need this to avoid greasy stools or severe indigestion.
Interestingly, a 2018 study published in Digestive Diseases and Sciences noted that while enzymes are great for "functional dyspepsia" (that painful, full feeling after eating), they aren't the primary treatment for chronic idiopathic constipation. The medical community generally looks toward motility agents or osmotic laxatives for that.
Why Your Gut Might Actually Be Lazy
We need to talk about motility. Digestion is a mechanical process as much as a chemical one. You can have all the enzymes in the world, but if the muscles in your gut aren't "squeezing" properly, nothing is moving.
This is why many people who think they need enzymes actually need more magnesium or better hydration. Or maybe they need to stop sitting at a desk for 10 hours a day. Movement begets movement. Sometimes, the reason digestive enzymes help with constipation for certain people is simply the "placebo plus" effect—they start taking the supplement, they become more mindful of their diet, they drink more water to swallow the pill, and suddenly things start moving.
It’s also worth noting that some enzyme blends contain ginger or peppermint. Ginger is a prokinetic, meaning it actually helps speed up stomach emptying. If your enzyme supplement has a significant dose of ginger, it’s probably the ginger doing the heavy lifting for your constipation, not the amylase.
The Dark Side: Can Enzymes Make Constipation Worse?
This is the part the supplement companies don't put on the label. High doses of certain enzymes, particularly those containing high amounts of calcium or certain proteases, can occasionally lead to harder stools in sensitive individuals.
There is also a rare but serious condition called fibrosing colonopathy, which was historically linked to incredibly high doses of pancreatic enzymes in children with cystic fibrosis. While you won't get this from a standard over-the-counter supplement, it proves that "more" is not always "better" when it comes to gut chemistry.
You’ve got to be careful with "brush border" enzymes too. These are the ones your small intestine produces, like sucrase and maltase. If you're over-supplementing, your body might get a little lazy. It’s always better to nudge the system rather than take it over entirely.
What Most People Get Wrong About Gut Health
We live in an era of "gut optimization" where we think we can hack every bowel movement with a pill. But constipation is often a symphony of errors. It could be a lack of bile flow—bile is a natural laxative, by the way—or it could be a Pelvic Floor Dysfunction where the muscles literally don't know how to relax.
If you are dealing with SIBO (Small Intestinal Bacterial Overgrowth), enzymes are actually a huge help. In SIBO, bacteria have moved into the small intestine where they don't belong. They eat your food before you do. By taking enzymes, you speed up absorption, effectively "starving" the bacteria in the upper gut. This can reduce the gas that causes the "ileus" (a temporary stop in intestinal movement) and get things flowing again.

Real-World Trial: Should You Buy Them?
If you're going to try this, don't just grab the cheapest bottle at the pharmacy. Look for "Full Spectrum" enzymes.
A good test is to take them with your largest meal for about five days. If you notice your bloating goes down, but your constipation remains, then enzymes aren't your solution. You likely have a motility issue or a fiber imbalance. However, if the bloating subsides and you find yourself going more regularly, you were likely dealing with "secondary constipation" caused by malabsorption and gas-induced slowing.
Actionable Steps for Better Transit
Stop looking for a "one pill" fix and try this sequence instead.
First, check your hydration. It’s boring, but if you're dehydrated, your colon will steal water from your stool, turning it into pebbles. Second, look at your fats. Healthy fats like olive oil or avocado oil stimulate the gallbladder to release bile, which acts as a natural lubricant for the colon.
If you still want to try enzymes to see if they help your constipation, look for a blend that includes:
- Lipase (at least 1,000 FIP units) to help with fats.
- Bromelain or Papain (from pineapple and papaya) which are gentle proteases that also have anti-inflammatory properties.
- Ginger root extract to help with that "squeezing" motion of the stomach.
Take the capsule about 10 minutes before you start eating. This gives the enzymes a head start to mix with the food as it enters the stomach.
Don't ignore the basics. Digestive enzymes help with constipation most effectively when they are part of a broader strategy. This includes eating in a relaxed state—your body cannot digest food well if you are in "fight or flight" mode—and ensuring you're getting a mix of both soluble and insoluble fiber.
If you have "pencil-thin" stools, severe pain, or haven't gone in over a week, stop the supplements and see a GI specialist. There could be a structural issue or a blockage that no amount of protease will fix.
For the vast majority, enzymes are a tool for comfort and absorption. They are the support staff, not the manager of the system. Use them to reduce the workload on your gut, and you might find that the rest of the "plumbing" starts working a lot more efficiently on its own.
