Laboratory results

You can check more than the label.

Every batch of Day One ISOLATE is sent for third-party testing, and the lab results are published. Sealed retail tubs go to Eurofins Food Testing Australia for protein and total fat analysis; each report carries its lot number, so you can see which batch was tested and what the laboratory found.

The summary below is our designed summary of the lab's report—the handwriting is ours, the numbers are theirs. The original PDF is always one click away. Your flavour selection here carries over to the shop below.

Every batch is third-party tested by Eurofins and the results are published against its lot number. Pick a flavour, read the report.

How to read the report
Not our letterhead—this is Eurofins’ own report, one of the world’s largest food-testing labs. We publish what they send back, PDF and all.
This lot number is printed on the base of every tub in the batch. Match it to yours.
73.6 g of protein in every 100 g of powder—weighed as received, moisture and all. No dry-basis inflation (more on that below).
× this flavour's 34.3 g scoop = 25.2 g per serve—beside the 25.1 g its panel declares.
Fat gets measured too—so you can hold the label’s fat line to the same standard.

What the testing covers

Covered: protein by nitrogen analysis and total fat in the submitted sample, per 100 g against the lot number.

Not assessed: taste, digestive comfort, heavy metals, banned substances, microbiology, allergens or amino spiking. Each report describes the sample tested, not every tub in the batch.

What “as received” means

The result includes the moisture naturally in the powder. "Dry basis" divides it out—same powder, bigger number. We publish as received, because your scoop weighs what it weighs.

Why no carbohydrate results

We publish only results we can confidently substantiate. Our laboratory measures protein, fat, moisture and ash, then reports the remaining mass as carbohydrate. It does not measure carbohydrate directly or use our full formulation. Non-carbohydrate ingredients not captured in those measurements are therefore counted as carbohydrate, potentially overstating the result.

We won't present a calculated remainder as verified carbohydrate content. Our batch reports publish laboratory-tested protein and fat results backed by the analytical report. For declared carbohydrate and sugar values, refer to the packaging's nutrition information panel.

Why we don't publish batch carbohydrate results

We publish only results we can confidently substantiate. Our laboratory measures protein, fat, moisture and ash, then reports the remaining mass as carbohydrate. It does not measure carbohydrate directly or use our full formulation. Non-carbohydrate ingredients not captured in those measurements are therefore counted as carbohydrate, potentially overstating the result.

We won't present a calculated remainder as verified carbohydrate content. Our batch reports publish laboratory-tested protein and fat results backed by the analytical report. For declared carbohydrate and sugar values, refer to the packaging's nutrition information panel.

What "as received" means.

The result includes the moisture naturally present in the powder. A "dry basis" figure divides that moisture out—same powder, bigger number. We use the as-received result and the labelled serving weight to calculate protein per serve, because your scoop weighs what it weighs.

FAQs

A few things you might want to know.

Is ISOLATE dairy free, lactose free and gluten free?

Yes. ISOLATE is gluten free, lactose free and dairy free by design. Our hydrolysed protein isolate contains no whey or casein—the proteins found in milk—giving you a clear alternative to dairy-based protein powders.

How does ISOLATE support digestion and gut health?

ISOLATE brings together dairy-free protein, added protease enzymes and 7 billion CFU of probiotics, with digestion built into the formulation.

Hydrolysis breaks protein into smaller fragments. Added protease enzymes help break down protein during digestion, while the probiotics are included to support gut health and digestion as part of your daily routine.

Everyday signs of comfortable digestion include regular, easy-to-pass stools and meals that don’t routinely leave you bloated, cramped or uncomfortable. These are useful signs, rather than a diagnosis of gut health.

For people with lactose intolerance, dairy can trigger gas, bloating and diarrhoea. Milk proteins can also trigger an inflammatory immune response in people with milk-protein allergy. These are different mechanisms, and digestive discomfort alone doesn’t establish inflammation.

ISOLATE is free from dairy—including lactose, whey and casein—so you can meet your protein needs without those dairy components.

Is ISOLATE allergen free?

ISOLATE is allergen free by design: we formulate without allergenic ingredients, and the product is gluten free and dairy free.

Our packaging also carries a precautionary facility statement about peanuts and tree nuts. That statement addresses potential manufacturing cross-contact; it does not describe ingredients added to ISOLATE. If you manage a food allergy, read the full statement for your chosen flavour.

When should I use it?

Make ISOLATE part of the routine that works for you: after training, alongside breakfast or between meals. It’s a convenient way to help meet your daily protein needs within a varied diet.

Can I see the reports before buying?

Absolutely. Browse the published results and open the original Eurofins laboratory reports before you order. See the numbers, check the lot and make an informed choice.

What do the independent reports prove?

The published Eurofins reports independently measure protein and total fat in the submitted samples. We show those results alongside the relevant lot information so you can see the evidence behind the numbers.

They verify composition; they aren’t head-to-head trials of ISOLATE versus whey for muscle growth, absorption or digestive comfort.

What does “as received” mean?

It means the laboratory tested the powder in the condition it received it, including its naturally present moisture. We use that result and the labelled serving weight to calculate protein per serve, rather than presenting a moisture-free figure.

Why aren’t batch carbohydrate results shown?

We publish results we can confidently substantiate. The carbohydrate-by-difference figure is a calculated remainder after protein, fat, moisture and ash are accounted for. Other components can fall into that remainder, so it isn’t a direct measurement of carbohydrate.

For your flavour’s declared carbohydrate and sugar values, refer to its nutrition information panel.

What if my batch isn’t listed?
