Does FODZYME Digestive Enzyme Support a Low FODMAP Diet?

If you’re following a low FODMAP diet and missing foods like garlic, onions, beans, or dairy, you’re not alone.

These are some of the most common FODMAP triggers, and for many people, they’re also some of the hardest to avoid long term. That’s where FODZYME®, a unique digestive enzyme powder, comes in.

As a dietitian specializing in gut health, I frequently receive questions about whether digestive enzymes can help manage IBS and FODMAP sensitivity.

In this post, I’ll walk you through what FODZYME is, how it works, what the research says, and who it may (and may not) be a good fit for. I’ll also share how to use it, along with where to buy it & my personal discounts.

What is FODZYME?

Unlike many generic digestive enzymes, FODZYME is specifically designed to target FODMAPs, the short-chain carbohydrates that can trigger symptoms in people with IBS.

The powdered blend contains three key enzymes:

  • Fructan hydrolase → helps break down fructans found in artichokes, banana (ripe), Brussels sprouts, cranberries, garlic, grapefruit, leeks, onions, peas, shallots, wheat, and more.
  • Alpha-galactosidase → helps with GOS (galacto-oligosaccharides), the fermentable carbohydrates in almonds, beans, cashews, chickpeas, lentils, and pistachio nuts.
  • Lactase → helps with lactose in dairy products, including cottage cheese, ice cream, kefir, milk, ricotta cheese, and yogurt.

Because it’s a powder (instead of a capsule), you can sprinkle it directly onto your food or mix it into a drink. This makes it easier for the enzymes to actually interact with your food before digestion begins.

And, FODZYME has been tested and certified low FODMAP by Monash University and FODMAP Friendly, which is excellent news if you’ve been looking for more flexibility on the low FODMAP diet.

Fodzyme is vegan, dairy, soy, gluten, and casein-free. It’s also made without artificial colors or flavors.

All ingredients are sourced from a US-based manufacturer and then mixed and packed in a US-based cGMP FDA-registered facility.

What does the research say?

FODZYME’s efficacy has been tested through SHIME (Simulator of the Human Intestinal Microbial Ecosystem), a scientifically validated human gut model.

  • Testing shows that FODZYME degraded up to 90% of fructans (from about 3 grams of garlic/onion) within 30 minutes.
  • In addition, 70% of released fructose was absorbed during simulated small intestinal transit, with a corresponding decrease in microbial gas production and a slight decrease in butyrate and short-chain fatty acid production. (1)

Tips on How to Use FODZYME

Here are a few tips if you decide to try it:

  • When to use it: Sprinkle FODZYME on food or mix it into a non-hot beverage at the start of your meal if it contains high-FODMAP ingredients, such as garlic, onions, beans, or dairy products.
  • Dosage: Start with ¼ teaspoon per meal. If your meal lasts longer than 30 minutes, you may need a second dose.
  • Temperature matters: Enzymes are sensitive to heat, so avoid sprinkling it directly on very hot food (above 140°F / 60°C).
  • Best timing: It often works best once you’ve completed the strict elimination phase of the low FODMAP diet and are in the reintroduction phase or beyond.

Who Might Not Benefit from FODZYME?

While FODZYME can be a game-changer for many, it’s not a fit for everyone.

  • It doesn’t target polyols (like sorbitol or mannitol) or fructose.
  • If you have fructose intolerance, breaking down fructans might increase your symptoms.
  • If your digestive symptoms aren’t related to FODMAPs, but instead to histamine intolerance, SIBO, gluten-sensitivity, celiac disease, or something else, FODZYME won’t help.

Should You Try FODZYME? My Dietitian Take

Many high FODMAP foods, such as beans, lentils, nuts, and onions, are rich in gut-nourishing fiber, prebiotics, and polyphenols.

With this in mind, targeted digestive enzymes can be beneficial, as research indicates a varied diet supports better gut and overall health.

While FODZYME isn’t a “free pass” to eat unlimited high-FODMAP foods, it can be a really helpful tool for expanding your diet and reducing the stress that comes with eating out or cooking for your family.

While FODZYME may not work for everyone, many of my clients who have tried it consider it a game-changer. They give it positive reviews and continue to use it on their favorite foods that are high in FODMAPs.

In a nutshell, using FODZYME supports better digestion of high FODMAP trigger foods, enabling you to enjoy many foods you love and miss!

Frequently Asked Questions about FODZYME

Yes. FODZYME is safe for daily use with meals that contain high FODMAP ingredients. Many people find it especially helpful when dining out or eating meals that may have hidden garlic, onions, or dairy.

Extensive testing by the development team reveals that mixing enzymes directly into food is the most effective way to deliver digestive enzymes.

FODZYME’s powder form maximizes its ability to break down FODMA{s before they arrive in the colon and cause GI distress.

I’ve personally tried FODZYME, and I can not detect any taste. However, some people with sensitive taste buds may detect a slight sweetness.

No, the texture of your food remains the same.

FODZYME helps break down fructans, GOS, and lactose, but it does not aid in the breakdown of polyols (such as sorbitol or mannitol) or excess fructose.

Think of it as a tool to expand your diet, not a free pass to eat everything without limits.

The FDA generally recognizes the enzymes in FODZYME as safe (GRAS). However, those with galactosemia, a highly rare hereditary condition, should consult with their healthcare provider before using FODZYME.

Additionally, to date, FODZYME has only been tested in adults. If you’re considering using it for a child with digestive issues, please consult with their pediatrician or a pediatric dietitian first.

No. FODZYME is meant to complement the diet, not replace it.

It’s best used once you’ve completed the elimination phase and are working on reintroducing foods or broadening your diet for long-term sustainability.

SCFAs (short-chain fatty acids), a byproduct of fiber fermentation, are a source of energy for colon cells.

They can improve gut barrier integrity and regulate the inflammatory response, making them beneficial to the gut and overall health.

In a simulated model, SCFA production was reduced with FODZYME. However, it was not depleted.

This potentially means that taking FODZYME with the appropriate high FODMAP foods may be more beneficial to gut health than avoiding them altogether.
