Use This to Choose an Enzyme Product

Houston Enzymes’ formulations target specific foods and issues, but also combine some enzymes for a broader approach.

1. For multiple food intolerances, use a strong broad spectrum enzyme

TriEnza Group


TriEnza is a combination of enzymes for multiple digestive intolerances.

TriEnza supports digestion for the 3 main types of foods: proteins, carbohydrates, and fats.

But TriEnza goes beyond the basics and provides digestive support in all these areas:

  • Food proteins
  • Gluten
  • Casein in dairy
  • Carbohydrates
  • Lactose intolerance
  • Polyphenolic vegetables and fruits
  • Fats in foods and supplements
  • Fibre

TriEnza was reformulated in 2019 to bring you better support for digesting a wide range of foods.

The changes made to TriEnza should result in a product better able to:

  • Break down gluten, dairy casein, soy, and meat protein.
  • Support digestion of the sugars sucrose and maltose, which will also be helpful for the gut microbiome.
  • Help with occasional gas and bloating through fibre breakdown.

TriEnza is available in capsules, chewables, or powder.


2. To target the breakdown of proteins including gluten, casein, and soy

AFP Peptizyde
  • Breaks down gluten, casein, soy, and other proteins.
  • High in the DPP IV enzyme.
  • May be used as an alternative to the GFCF diet (gluten-free, casein-free diet), or used with GFCF if you are wanting to address other proteins still in the diet.

AFP Peptizyde is a blend of protease enzymes that break down only proteins, including gluten and dairy casein.

3. These products mostly target carbohydrates, but have some enzymes for proteins and fats too
Zyme Prime 90 Web FRONT

Zyme Prime
  • Breaks down carbohydrates, fats, starches, and sugars.
  • Helps with gas and bloating.
  • May help with undigested food in the stool.
  • Great for lactose intolerance.

Zyme Prime™ helps some with proteins (but not a GFCF alternative). Tends to firm stools when used alone.

Zyme Prime is available in capsules.

ZyCarb 90 FRONT Web3

  • ZyCarb™ is a variation of Zyme Prime that shouldn’t be as stool-firming.
  • Breaks down carbohydrates, starches, and sugars.
  • Helps with gas and bloating.
  • May help with undigested food in stool.
  • Great for lactose intolerance.
  • Includes some of the No-Fenol in it (about 1/3 of the main enzyme).
  • No cellulase so no concern about taking it with time-released meds.

ZyCarb helps with the foods previously mentioned for both Zyme Prime and No-Fenol, and also some for fats and proteins (not a GFCF diet alternative). If you want something more stool-firming, try Zyme Prime instead of ZyCarb.

4. For polyphenols and fibre

No Fenol 90 FRONT Web3


  • Targets breakdown of the fibre in fruits and vegetables
  • Supports digestion of polyphenolic foods
  • Tends to soften stools (should not cause diarrhoea)

Xylanase is the major component of No-Fenol, and is an enzyme used to breakdown the structural components of plant cell walls, which are primarily complex carbohydrates.

All plants contain some degree of polyphenolic compounds, with brightly coloured fruits and vegetables at the higher range.

The research literature indicates that some phenolic compounds are modified by the addition of carbohydrate groups to their structures, which may inhibit their crossing into cells and being metabolized. The current hypothesis for why

No-Fenol may help is through the ability of the enzymes in this product to remove the carbohydrate groups from the polyphenols, thus allowing normal processing by the detoxification pathways.

There is no evidence that No-Fenol directly modifies polyphenolic structures. The success of No-Fenol in allowing phenolic foods back into the diet may result in a re-evaluation of the basis of the polyphenol “problem”. The polyphenols are not destroyed, but proper assimilation of phenols is supported.

5. For fats

Lypazyme 120 FRONT3

  • Breaks down triglyceride fats in foods
  • Supports the keto diet
  • Helps gas and bloating from fats and oils
  • Contains 3 types of lipase enzymes

Lypazyme is a combination of 3 different lipase enzymes. Lypazyme is unique in the use of multiple forms of lipase to ensure complete breakdown of the triglyceride fats found in foods and many supplements.

Lypazyme may help with the gas and bloating from high-fat meals and supplements (such as fish oil), or after gall bladder removal.


6. For occasional constipation

Biomuve 90 Rendering FRONT5

  • Helps maintain regularity and healthy bowel movements
  • Supports a healthy microbiome
  • Breaks down fibrous foods for digestive support
  • Combination of enzymes, prebiotics, and probiotics

Biomuve® is a blend of xylanase enzyme, probiotic bacteria, and prebiotic botanicals that promote regularity and healthy gut bacteria.

Biomuve contains Actazin®, an extract from kiwi fruit which is a natural source of prebiotics, fibre, and enzymes. Actazin may also nurture the probiotic bacteria provided by Biomuve.

Biomuve includes DE111®, a probiotic blend of Bacillus subtilis, which may help support regularity in the digestive tract.

Xylanase is added to Biomuve as an enzyme that can break down hemicellulose to release nutrients from foods with a high fibre content. Xylanase can also help soften stools as it breaks down soluble fibre in vegetables, grains, and legumes.

Still don’t know where to start?

If you are unsure as to which enzyme product is needed, use a broad spectrum enzyme product such as Zyme Prime or TriEnza.

Adjusting to Zyme Prime is not difficult. Zyme Prime is mild and low in proteases (protein-digesting enzymes). Zyme Prime should not cause discomfort and is a good starter product for the sensitive gut.

If desired results are not observed using Zyme Prime, either increase the dose, add another product (AFP Peptizyde or No-Fenol) or switch to TriEnza.

TriEnza contains multiple types of enzymes for proteins, carbohydrates, fats, and polyphenolic foods. TriEnza is higher in proteases than Zyme Prime.

TriEnza has DPP IV activity and, like AFP Peptizyde, may be an alternative to the gluten-free, casein-free (GFCF) diet.
