Digestive Enzyme Supplements NZ: A Label-First Buying Guide
You pick up a bottle whose front label promises digestive support. It sounds useful, but the front does not yet tell you what the formula is designed to act on. Turn the bottle around and the practical information appears: enzyme names, unfamiliar units, serving directions, other ingredients and warnings.
The most useful digestive-enzyme label identifies the enzyme, what it is intended to act on, its declared activity, the serving instructions and relevant cautions. More ingredients or more milligrams do not automatically make a product better.
The useful information is on the back
Words such as digestive support, advanced and broad spectrum can describe a product category, but they do not give you enough information to choose between digestive enzyme supplements NZ shoppers may find online or in stores.
A front panel cannot show whether a formula matches the food component you have in mind, whether enzyme activity is declared, how large the full serving is or whether an allergen is present. The reverse panel is where a useful buying decision begins.
This is a label-reading exercise, not a way to diagnose an enzyme deficiency. Digestive symptoms can have many causes, and a supplement bottle cannot identify them.
Turn the bottle around: the reverse-label audit
Read the panel in this order. Each item answers a different buyer question.
- Enzyme identity: What enzyme is actually present? Look for a specific name such as protease, actinidin, amylase, lactase or lipase.
- Target food component: Is the enzyme intended to act on protein, starch, lactose, fat or another component?
- Activity unit: Does the label declare activity under a named assay, or only an ingredient weight?
- Amount per serving: Is the figure listed per capsule, per tablet or per full daily serving?
- Serving timing: Does the label say to take the product with food, before food or on another schedule?
- Other active ingredients: Does the formula also contain a prebiotic, fibre, herb, vitamin or another non-enzyme ingredient?
- Allergens, cautions and storage instructions: Who should avoid the product or seek advice, and how should it be stored?
The order matters. It prevents a large milligram figure or a long ingredient list from doing all the persuasive work before you know what those numbers mean.
First find the food component
Enzymes are associated with particular reactions. Start with the food component a formula is intended to act on, then check whether the named enzyme and activity declaration make sense for that purpose.
| Food component | Enzyme you may see | Possible label units | Important limit |
|---|---|---|---|
| Protein | Protease or actinidin | HUT, CDU or another defined assay | The label cannot diagnose why you experience symptoms. |
| Starch or carbohydrate | Amylase | DU or another defined assay | The label cannot diagnose why you experience symptoms. |
| Lactose | Lactase | ALU, FCC units or another defined assay | The label cannot diagnose why you experience symptoms. |
| Fat | Lipase | LipU, FIP, USP units or another defined assay | The label cannot diagnose why you experience symptoms. |
Not every product uses the same unit system. The map helps you connect a food component with an enzyme, but it does not tell you whether you need a supplement or why a symptom occurs.
Milligrams and activity units answer different questions
Milligrams describe weight. On an enzyme supplement label, that may be the weight of an ingredient or an enzyme preparation. Weight alone does not state how much enzyme activity the preparation shows under a defined test.
Activity units describe activity measured under a specified assay. The test looks at a particular enzyme reaction under set conditions. That is why a protease, amylase, lactase and lipase may be described with different units.
- Some products display weight, activity or both.
- A larger milligram number does not automatically mean greater enzyme activity.
- Units from different enzymes and assays are not one universal potency scale.
- A disclosed activity unit does not guarantee a finished-product benefit for every person.
- More enzyme ingredients do not automatically make a formula more suitable.
For a practical comparison, compare like with like: the same enzyme, the same activity unit, the same serving basis and similar directions. CDU should not be ranked directly against DU, HUT, ALU or LipU as though the largest number wins.
Five back-label patterns
These fictional patterns show what different labels establish, what they leave open and what to ask next. They are not product rankings.
Pattern one: The targeted enzyme
Representative panel: Lactase with activity declared in ALU, with directions to take one capsule with food containing lactose.
What the label establishes: It identifies one enzyme, one food component, an activity unit and a timing direction.
What remains unknown: It does not establish why a person reacts to dairy, whether the serving suits them or whether another ingredient is relevant.
The next question a shopper should ask: Is the activity listed per capsule or per full serving, and are there age or allergen cautions?
Pattern two: The broad-spectrum blend
Representative panel: Protease in HUT, amylase in DU, lactase in ALU and lipase in LipU, with each role and activity shown separately.
What the label establishes: Several enzymes are included for different food components, and the activities are not hidden inside one total.
What remains unknown: The panel does not prove that every enzyme is needed, that the blend is clinically superior or that it will suit a particular symptom.
The next question a shopper should ask: Do the serving size, timing, activity declarations and cautions fit the intended use?
Pattern three: The weight-only formula
Representative panel: Protease preparation 200 mg and amylase preparation 150 mg, with no activity units.
What the label establishes: It discloses the weight of each preparation.
What remains unknown: It does not state the measured enzyme activity, so the milligram figures cannot be read as direct potency values.
The next question a shopper should ask: Can the manufacturer provide the activity specification and assay used?
Pattern four: The proprietary blend
Representative panel: Digestive enzyme complex 500 mg, followed by several enzyme names but no individual amounts or activities.
What the label establishes: The listed ingredients are included and the total blend has a stated weight.
What remains unknown: The contribution and activity of each enzyme are unclear.
The next question a shopper should ask: Are individual activities available, and does the total blend figure refer to one capsule or the full serving?
Pattern five: The dual-purpose formula
Representative panel: An actinidin-containing green kiwifruit extract with CDU activity, plus a separate gold kiwifruit prebiotic ingredient.
What the label establishes: The formula combines an enzyme component with a non-enzyme component that has a separate intended role.
What remains unknown: Enzyme activity does not measure prebiotic function, and two purposes do not make a product a broad-spectrum enzyme blend.
The next question a shopper should ask: Are the activity, ingredient weights, serving size and cautions disclosed separately?
What the label can prove and what it cannot

A clear label is valuable, but disclosure and proof are not the same thing. An ingredient study, an in-vitro assay, human research and finished-product evidence answer different questions. Evidence for one should not be presented as proof of another.
Why Our Kiwifruit Label Shows Both Milligrams and CDU
Our live NZ-grown kiwifruit prebiotic and enzyme formula label shows two types of information because they answer different questions.
Each capsule contains 300 mg of NZ-grown gold kiwifruit powder and 250 mg of NZ-grown green kiwifruit enzyme extract. The serving size is two capsules, and that serving provides 12,500 CDU of declared actinidin activity.
The green kiwifruit extract is the actinidin-containing enzyme component. Its milligram figure describes the quantity of extract. CDU describes declared actinidin activity under the relevant assay. A shopper can therefore see both how much extract is present and the activity declared for the full serving.
The gold kiwifruit powder is a separate prebiotic component. Its role should not be measured with the enzyme activity unit. This is a dual-purpose formula, not a broad-spectrum digestive-enzyme blend for every macronutrient. It does not contain every enzyme discussed in this guide.
CDU also should not be ranked directly against unrelated units such as DU, HUT or ALU. They describe different assays and reactions.
The label states that the product contains kiwifruit, is gluten free and is suitable for vegetarians. Pregnant or lactating customers are advised to seek professional health advice. The formula is not a treatment for food intolerance, pancreatic disease, IBS or persistent digestive symptoms.
When should a digestive enzyme be taken?
Timing is formula-specific. Some products direct people to take them with meals, shortly before food or according to another defined schedule. Follow the directions for the individual product rather than applying one timing rule to every enzyme.
For the Kiwi Superfoods formula, the current live label says to take two capsules per day with water. It may be taken with or without food. Those directions should not be replaced with a general rule taken from a different enzyme product.
A supplement or a medicine?
General dietary supplements are retail products intended to supplement the diet. Some retail products are targeted to a particular food component, such as a lactase product intended for lactose in a meal.
Pancreatic enzyme replacement therapy is different. These are medicines used for defined medical needs when the pancreas is not providing enough digestive enzymes or when enzymes are not mixing properly with food. Dosing and meal timing are managed with a doctor or dietitian.
Prescription pancreatic enzymes are not interchangeable with an ordinary retail digestive supplement. Do not replace prescribed treatment with a retail formula, change a medicine dose from information in this article or use symptoms to diagnose pancreatic insufficiency.
Safety stop signs
Pause the supplement search and seek professional assessment for persistent or worsening digestive symptoms, significant abdominal pain, blood in stools, unintentional weight loss, ongoing vomiting, persistent diarrhoea or constipation, major unexplained bowel changes, suspected malabsorption or a diagnosed gastrointestinal or pancreatic condition.
Ask a qualified health professional before supplementation if you are pregnant or lactating, have a kiwifruit allergy, take prescription medicines, are choosing a product for a child or manage complex health conditions.
Educational note: This guide supports label reading and general buying decisions. It does not diagnose symptoms, recommend treatment or replace advice from a qualified health professional.
Frequently asked questions
What should I look for on a digestive enzyme supplement label?
Look for the enzyme name, the food component it is intended to act on, a declared activity unit where available, the amount per serving, timing directions, other ingredients, allergens and cautions.
Are milligrams or activity units more useful for enzymes?
They answer different questions. Milligrams describe ingredient or preparation weight, while activity units describe measured activity under a defined assay. A label showing both usually gives more context than weight alone.
What do DU, HUT, ALU, LipU and CDU mean?
They are assay-specific activity units commonly associated with amylase, protease, lactase, lipase and casein-digesting protease activity such as actinidin. Test conditions differ, so the numbers are not interchangeable.
Is a broad-spectrum digestive-enzyme blend always better?
No. More enzymes may cover more food components, but that does not prove the blend is more suitable, more active or better supported for an individual buyer.
Can a supplement label prove that a product will help bloating?
No. A label can disclose ingredients, activity, directions and cautions, but it cannot identify the cause of bloating or guarantee an individual result.
When should digestive enzymes be taken?
Follow the individual label. Timing may be with food, shortly before a meal or on another schedule. The Kiwi Superfoods label says two capsules daily with water and allows them to be taken with or without food.
Are retail digestive enzymes the same as prescription pancreatic enzymes?
No. Prescription pancreatic enzymes are clinician-managed medicines for defined medical needs and are not interchangeable with ordinary retail digestive supplements.
What does the Kiwi Superfoods label disclose about actinidin activity?
It states that a two-capsule serving provides 12,500 CDU of actinidin activity, alongside 500 mg of NZ-grown green kiwifruit enzyme extract per serving.
Next steps
Keep the buying sequence simple: food component, enzyme, activity unit, serving directions, then cautions. This order helps you compare what a label actually discloses without assuming that the longest blend or largest milligram number is automatically best.
