Whey Isolate NZ

Whey Protein Isolate (WPI) is premium ion exchange protein powder. Our product is made in New Zealand (NZ) from grass fed cows.

Whey is a milk product and is a by-product of cheese. Whey contains high levels of protein with some lactose and fat. Isolate (this product) is made by further refining whey to remove virtually all of the lactose and fat, leaving a product that's ultra-high in protein with a superior Branched Chain Amino Acid (BCAA) profile.

WPI is a concentrated protein powder for muscle development. It has a very strong amino acid profile and is one of the most beneficial dietary sources of protein. It's very easy to digest and absorbs rapidly, making amino acids readily available to be utilised by muscles. It's a very beneficial protein supplement for post exercise when it is able to digest easily without fat to slow absorption.

It has a pleasant, clean taste and is popular with athletes and those counting their macro-nutrients. It's also generally suitable for those with lactose intolerance.

Whey Isolate Benefits

WPI is a powerful muscle builder because it has all 21 amino acids needed for growth and repair. Each serving (unflavoured) contains over 29 grams of protein and nearly 8 grams of BCAAs.

WPI has higher levels of leucine than other protein powders. In fact, WPI has more than 30% more leucine than WPC. Studies of leucine have shown it to be the most anabolic (growth promoting) amino acid for muscle growth and recovery. Leucine also contributes to the regular of blood sugar levels, growth hormone production and wound healing.

WPI may assist atheles to benefit from increased lean muscle mass, reduced muscle atrophy during exercise, improved muscle repair and recovery (hyperatrophy), and an increased metabolic rate.

Other Benefits:
Whey is composed of several bioactive fractions including glycomacropeptide, β-lactoglobulin, α-lactalbumin and lactoferrin. These have health benefits against cancer, infection and inflammation.

WPI is high in cysteine and studies have shown that WPI can increase glutathione synthesis to improve antioxidant defence. Glutathione is a natural antioxidant that the body produces from several other amino acids - especially cysteine.

New Zealand dairy cows whey production

Best Whey Isolate NZ

We believe that the best milk proteins are made here in New Zealand (NZ) because the dairy cows that produce the milk used to create this product are naturally grass fed and not factory farmed. 

NZ has a temperate climate which allows natural grazing all year round. Dairy cows are not factory farmed in NZ and it is reflected in the quality of the milk produced which is related to the environment and their diet.

NZ is the largest dairy exporter in the world and has rigorous standards to protect the integrity of the industry. The NZ government enforces strict testing and quality standards for milk production, and antibiotics and hormones are managed carefully against being in milk.

Though the fat in this product is very low, it is worth noting that cows that consume a grass fed diet produce milk with significantly more omega-3 fatty acids than grain fed cows. Pasture fed cows produce milk with nearly twice as much omega-3 than their counterpart, with a ratio of omega-3 vs omega-6 around 1:1. This may be another benefit as diets high in omega-3 are believed to support heart and immune system health. Grass fed cows have milk that's also richer in vitamin E and beta-carotene.

Bioavailability

Protein digestibility is a measure of the proportion of protein that is absorbed by the body. WPI scores 100% on this scale.

Biological value is a measure of the proportion of absorbed protein that's retained for growth and maintenance. WPI scores 104 on this scale.

The Protein Digestibility-Corrected Amino Acid Score (PDCAAS) is a rating that determines the bioavailibility of a protein. The maximum score is 1.0. WPI technically scores 1.0 because traditionally protein quality was measured against milk, which scored 1.0. Though the scale only goes up to 1.0, realistically it may be up to 1.21, which is the highest of all protein sources.

Whey Isolate Side Effects

Whey isolate is generally well tolerated, even by those with lactose intolerance. WPI is a milk product so those with milk intolerances and vegans should avoid this product.

Our Verdict

Whey isolate is whey that's further refined to remove virtually all lactose and fat. The resulting protein and BCAA levels are higher but it's also more expensive than whey concentrate (WPC).

It is a superior protein powder because it has the most concentrated amino acid profile and is absorbed rapidly without fat to slow digestion. It surpasses other proteins for bioavailability so is the best protein powder for post exercise for those wanting maximum muscle recovery/development.

It is more expensive so consideration must be taken whether WPI is better suited to your requirements vs regular WPC. This decision comes down to personal preference.

Best taste.
Best mixability.
Best to stack with a whole lot of grosse tasting supplements.
I'm also lactose intolerant, it seems to me that NZProtein Whey Isolate is the only dairy based I can consume without adverse reactions.
I highly recommend this product, and flavour. I'l be coming back time and time again for it.
Oh, and I almost forgot NZProtein also have the best prices and best levels of service. IMHO.

I purchased both the banana and double choc flavours and both are great. They mix well into both liquids and food such as yoghurt and oats. There's no sickly sweetness or artificial after taste, they're both absolutely delicious.

mixes well, great quality and I really want to give this a five star. But i cant get used to the smell and taste, which come off as too artificial. Still I'm willing to try other flavours, perhaps banana or just go plain.

Very noticeable reduction in back-end issues compared to regular whey, as someone who has minor lactose intolerance. Very mild taste.
Review by: Albert on Mon, Aug 19, 2019 8:58 AM
it would get a 5 stars if they used Sunflower lecithin rather than soy. This is the only reason preventing me to use it every day and often. A part from that the taste(chocolate) is really good, mixes well and it does not leave me with stomach upset or cramps as other powders I bought. Overall very good product
Review by: Fabio on Mon, Aug 19, 2019 6:57 AM
I love NZ Protein products and then isolate is just one of them. It's been my whey and isolate of choice for round 4 yrs.

Flavours are great and the team are awesome.

Thanks again for my fix.
Review by: Joanna on Mon, Aug 19, 2019 1:10 AM
Tired a lot of brands and this is honestly the best tasting protein iso I’ve found.
Review by: Ben on Mon, Jun 24, 2019 7:37 AM
Just want to thank you for your excellent service and awesome proteins. I have been bodybuilding for past 6yrs here in Perth Western Australia originally from Hawkes bay NZ. I have had a lot of different proteins over the years training I must say this is extremely good. I was using true protein as it was the best here in the local market but since having your NZ Protein It's even better on the stomach and recovery after training heavy in the gym. I will definitely be spreading the word here in Perth and at the gyms as I hope you grow your market share as the product is fantastic keep up the excellent work and service.

Best protein i have ever tried
Review by: Harpreet on Sat, Oct 6, 2018 10:37 AM
Brilliant protein powder. The unflavoured protein powder mixes in perfectly is so many meals without changin the taste in any way. The only difference is the texture is slightly creamier but that’s still nice in most meals.

I will definitely be getting more of this for my next order. It’s by far the best and most reasonably priced in the market.
Review by: James on Wed, Jun 13, 2018 8:11 AM
Great product all round, tastes best with milk

I have an allergy to whey. I've tried multiple other proteins. This is the only one I've found which tastes great and doesn't spark up my allergy! As well as my shakes I use it in all my baking too! Love it!!!

Not usually a Chocolate flavour fan, but the dark Choc is pretty damn tasty. Doesn't have that plastic-fake-sugar aftertaste that most Chocolate powders have. Mixes well & nice consistency.
