Naturally flavoured, with 29g of protein and 7g of BCAAs per serving, it's built for those who want maximum protein delivery without the extra load, and HASTA testing means it's safe for tested athletes to use with confidence.

FAQs

How is Whey Isolate different from Clean Nutrition Whey Protein?
Isolate goes through an additional filtration step that removes more of the fat, carbs and lactose, leaving a leaner, more concentrated protein source, ideal if you want maximum protein with minimal extras.

Is Clean Nutrition Whey Protein Isolate suitable for lactose-sensitive individuals?
The filtration process removes the majority of lactose, making it easier to digest for most people with mild sensitivity. It is not lactose-free and is not suitable for those with a dairy allergy.

Is it safe for tested athletes?
Yes. Clean Nutrition Whey Protein Isolate is HASTA tested for banned substances, giving athletes competing under anti-doping codes added assurance.

When's the best time to take it?
Within 30 minutes to an hour after training for optimal absorption, or any time you need a quick, low-carb protein boost.

Some batches of these products list thaumatin as the sweetener when it’s actually sucralose, which is approved in New Zealand and used intentionally in many other Clean Nutrition products. These products remain safe to consume.

New batches are sweetened with a stevia and monk fruit blend, and labels are being updated as existing stock sells through. Flavours without a note under the add to cart button aren’t impacted.
