Who should use TriEnza?

If you need support for digestion of multiple types of foods, try TriEnza.†

What’s new & improved with TriEnza?

As of August 31, 2023 we’ve made a few updates to the TriEnza 180TriEnza 90, and TriEnza Chewable formulas to bring you even better support for digesting a range of foods. The same changes will be made to the 60 count capsules and powder versions within the coming weeks. 

 The changes we made to TriEnza 180:

  1. Removed Cellulase and Glucanase enzymes.

    Recent research in animals indicates that cellulose fiber plays an important role in the development and maturation of the gut microbiome. Dietary cellulose induces cellular anti-inflammatory mechanisms from the gut bacteria and increased probiotic diversity. Breakdown of cellulose by supplemental cellulase may possibly remove the benefits to the gut bacteria and also produces higher glucose levels in the small intestine. With these new benefits of cellulose revealed, we feel it best to remove cellulase from ALL of our enzyme products.

    Glucans have much research backing their benefits in heart health. We find no reason to add an enzyme that breaks down glucans, so glucanase will be removed from our products as well.

    One fiber that should be broken down early in digestion is xylan which is found as a supporting structure in plant cell walls. Xylanase breaks down xylans into xylose sugar which is not absorbed in the human gut and so does not have a glycemic contribution. Xylans are the structures that tie cellulose fibers together, when xylan is broken down, the cellulose fibers are released and used normally by the gut bacteria. Houston Enzymes is one of the few companies to use xylanase in high amounts, because it also contains enzyme side activities helpful in release of absorbable polyphenols. No other enzyme company comes close to the level of xylanase used in Houston Enzyme products!

  2. Increased amounts of lactase, invertase, and lipase.

    With more room available in the capsule, we slightly increased the activities of lipase, lactase, and invertase to better help with sugar and fat digestion and lactose intolerance.

  3. Added Alpha-Galactosidase.

    We felt TriEnza needed more help with reducing problems produced by beans, broccoli, cauliflower and other veggies, so alpha-galactosidase was added back into the formula.

Contraindications for Enzyme Supplementation

These enzymes should be used with care in cases of active stomach or duodenal ulcers, severe bowel inflammation (characterized by blood in stools), hemophilia and other bleeding disorders, or within a week of scheduled surgery. This product may not be appropriate for those with known allergies to Aspergillus enzyme proteins, though non-specific mold allergies do not necessarily preclude use of fungal enzymes. Consult your medical doctor for further advice, and err on the side of caution. Those with known anaphylactic allergic reactions to fungal proteins should NOT ingest fungal-derived enzymes.


Two (2) capsules per meal or as needed. Less may be adequate for smaller meals. Most find using 2 to 4 capsules per meal adequate, and most likely no further benefits will occur with higher dosing, though more may be given for the infrequent and large food challenges. Each person is different so we encourage some experimentation to find the dose that best helps each person.
