Pure NZ Whey Protein Isolate powder

Kiwi Nutrition Whey Protein Isolate is 100% pure grass fed NZ whey protein isolate. It is refined from milk produced right here in NZ and then delivered direct to you with absolutely nothing added. It has a clean, natural taste which makes it highly versatile - it can be added to your favourite smoothies or baking without changing the flavour. 

Our whey protein isolate is perfect for those wishing to maximise their protein intake while minimising carbohydrates and fats. It is great for competitive sports people, multisport athletes, those undergoing bariatric surgery or on a keto diet or people who wish to minimise carbohydrate and fat intake.

We have samples of our whey protein isolate available here.

Our unflavoured whey protein isolate offers an impressive 28 grams of protein with 8 grams of branch chain amino acids (BCAAs) and 5.3 grams of glutamine per 30 gram serving.

Love this protein powder

Hi have the Vanilla and Chocolate. It mixes really well and tastes nice, not too sweet. I am using it as part of my weight loss and I find it's good to have a quick and easy way to get protein in my daily food plan. I am really enjoying these products.

Great product!

It was my first time buying WPI and I liked it. It is easy to use, flavourless and I feel no texture. I use it for shakes and for cooking. I made a fantastic keto pizza base! I will definitely buy it again. Thanks
