High protein, barely any sugar
Protein without the extras. Most flavoured proteins carry added fillers, fats and sugar. This is built on 90% whey protein isolate, so each 25g scoop gives around 20g of protein (about 80g per 100g) with under 1g of sugar, under 1g of fat and roughly 93 calories.

- Low-carb, low-sugar — 1.6–2.5g carbs and under 1g of sugar per 25g serve, at ~93 Cal.
- 5.6g of BCAAs per serve — including 2.5g of leucine, naturally occurring in the whey.
- Naturally sweetened — stevia and thaumatin only; no sucralose and no artificial flavours.
- Gluten-free isolate — 0.0g gluten on the panel; fast-absorbing for after training.

New Zealand whey, made in Tīrau

Shake, blend or stir it in
- Shake it: add one 25g scoop to 250–300ml of cold water or milk in a shaker and shake hard for 20–30 seconds.

Questions, answered
How much protein is in each serve?
Around 20g per 25g scoop. Chocolate gives 20.2g and Vanilla 20.1g of New Zealand whey protein isolate — about 80g per 100g. Each serve also has under 1g of sugar, under 1g of fat and roughly 93 calories, plus 5.6g of naturally occurring BCAAs including 2.5g of leucine.
Is this whey isolate or whey concentrate?
It's a 90% whey protein isolate. Isolate is filtered to a higher protein percentage than concentrate, which means more protein and less carbohydrate, fat and lactose per serve. That's why each 25g scoop lands around 80% protein by weight with under 1g of sugar and a low carb count.
What sweetener is used — is there any sucralose?
No sucralose. It's sweetened only with stevia and thaumatin, two naturally derived sweeteners, and uses natural flavouring — no artificial sweeteners or flavours. Vanilla uses natural vanilla flavour; Chocolate adds real cocoa powder. Both keep added sugar under 1g per serve.
Does it contain milk or other allergens?
Yes — it contains milk. This is a dairy-based whey, so it is not vegan or dairy-free. It may also contain traces of soy, lupin, almonds and cashews, as it's made in a facility that processes a range of products. It is gluten-free, with 0.0g of gluten on the panel. Always read the on-pack label.
What's the best way to mix it?
Shake hard, or blend for the smoothest result. Add one scoop to 250–300ml of cold water or milk and shake firmly for 20–30 seconds. For an extra-smooth, creamy shake — or if you like it thicker — give it a few seconds in a blender or stir it through yoghurt, oats or a smoothie.
Is it suitable for low-carb or keto diets?
It's low in carbs and sugar. Each 25g serve has just 1.6–2.5g of carbohydrate and under 1g of sugar, so it fits easily into low-carb eating. It isn't a meal replacement — use it alongside a balanced diet. If you follow a specific medical diet, check with your healthcare professional first.
How do shipping and returns work?
