What is Pure NZ Casein?

Pure New Zealand Casein, is a 100% Casein protein supplement, it's termed a 'slow' protein due to the very long time it takes to digest. Much longer than all other protein powders. Genuine 100% Casein products mix up very, very thick (this is one way to identify real 100% Casein). Pure NZ Casein is carefully made from fresh New Zealand grass fed milk, to create an extremely high protein concentration (similar to that of Whey Isolate). It contains high natural levels of BCAAs (Branched Chain Amino Acids), and virtually zero fat and carbohydrates (lactose) per serve. Because it contains close to zero lactose it makes it a great option for those that are usually sensitive to milk. The protein percentage in Pure New Zealand Casein is around 92% (or 97% by dry basis).

Having such an ultra low carbohydrate and ultra low fat content, Pure New Zealand Casein is often a first choice for bodybuilders, physique competitors or dieters who are paying meticulous attention to calorie intake. It's also often used as a 'night time' protein, taken before bed to provide a steady and sustained release of protein during sleep hours.

New Zealand Made Casein

Reactiv Pure New Zealand Casein comes from milk sourced from local kiwi farms, and is proudly made here in New Zealand.

How To Use Casein Protein

Reactiv Pure New Zealand Casein mixes best with water in a blender. When compared to Whey, it mixes up very, very thick. If you prefer less thickness then use more water and less powder. Due to its super thick consistency it can take some work to master mixing it, but when successful it has a smooth texture that is satisfying and filling. It also makes a great ingredient to make high protein mousse and dessert ideas.


We use lightweight resealable packaging, and mini tubs.


100% Calcium Caseinate (from New Zealand Milk), Monoglycerides (E471 – may contain trace Soy).

Great High Potency Casein

I love this stuff. If you use a shaker, it does clump a bit compared to Reactiv's micellar casein protein, but I blend it in a breakfast smoothie which it's perfect for.

It's sustained release can give either the perfect morning start, or an overnight refuel if you're looking to get your calories up &/or maintain more of an anabolic state during the 8-10hrs between dinner & breakfast.

It costs a bit more than the micellar casein, but it lasts an extremely long time because it's potency means you require less scoops for the same amount of protein, plus each bag is bigger than the usual 1kg that other brands offer. There's a lot of benefits & uses for this particular protein, so I'd definitely recommend!

Clean with no unnecessary flavouring or additives. Fully support this product amongst many that are filled with toxic garbage. Tastes great once mixed up.

Casein Powder

I absolutely love this. Mix it with my night time drink. Doesn't have a funny texture like some powders and can't taste it.

I'm so pleased found this product.

Filling and a good option for mixing with whey

This is filling, it mixes up thick, which helps me from getting hungry. It takes longer to mix than whey but it's smooth once done. What I like is it has almost no carbs and no fat, zero really, and really high protein, and all pure. I have it at night, and sometimes add a scoop to my daytime whey shakes. It works well for my eating which is sometimes keto. I'm having better recovery from training while using it and sleeping better. Very useful.
