Our NZ Whey Protein Isolate is sourced in New Zealand and is one of the most superior WPI protein powders on the market today. It is undenatured and sourced from Grass Fed Dairy Cows that live on and enjoy the naturalness of New Zealand’s great and nourishing green pastures all year round.

NZ WPI is made from cheese whey and is processed through cross flow micro-filtration and ultra-filtration to enable the protein to remain undenatured. It contains only 1% fat and 1.2% carbs whilst being over 93% protein (dry basis - natural flavour).

The flavoured varieties are made with Organic Flavours & Natural Sweeteners making it tasty and ideal for those who want to enjoy a healthy protein shake or as a pre and post workout supplement. The facts are:

  • Cross Flow Micro-Filtration naturally isolates undenatured protein due to its low temperature process.

  • From Pasture Fed Cows that graze on grass and clover pastures.
  • Free from Genetically Engineered Recombinant Bovine Growth Hormone (rBGH).
  • Free from acid processing.
  • Very High Level BCAA’s (Branch Chain Amino Acids) as it has around 30% more than other traditional whey protein powders helping to increase protein synthesis.

NZ WPI

17 August 2017
I did lot of research online about protein supplement powder. My finding and what everybody was/is saying is to look for ‘what’s in the powder – ingredients’. I find NZ WPI (that’s what I use) of very high quality. One of the most important thing I look for is the ‘source’ and as their products are sourced from Grass fed cows it is a big positive tick from me along with the use of organic flavours and sweeteners (Stevia) – all natural. As it doesn’t have the ‘unwanted/nasty’ ingredients, it gives me confidence and peace of mind that I am taking an excellent product. Thank you to the team at Professional whey for the amazing product(s) and all the hard work they put in to make it available to us. Very happy customer and I highly recommend it!

Clean, not too sweet, and no side effects

By: on 5 April 2017
I had stopped drinking whey protein because I couldn't find one that wasn't overloaded with flavour and sweeteners. I am also sensitive to dairy (gives me sinus problems amongst other things). I was getting side effects from other whey proteins but this one seems to be fine. I got the mixed sampler pack and my favourite flavours were vanilla and cacao.
(5)

NZ WPI - Amazing

By: on 9 March 2017
I've been drinking protein powders for pre and post gym and for meal replacements for the past 10 years and I find NZ WPI to be the best! It mixes easily with water. It tastes great and has a high protein content per serving. With no added fillers or nasties it's perfect for my post workout drink. Add a good price for this high quality delicious WPI and you have a five star rating. You can't go wrong, highly recommend it!
(5)

THE BEST

By: on 21 February 2017
Seriously so incredibly tasty and no nasties. I used to hate protein shakes but now I look forward to them. Delivery is fast and easy. Can't say a single bad thing about it.

NZ WPI

By: on 9 February 2017
I have been having this product on an almost daily basis for breakfast for the last 5 years. It is a good start to the day. I have the natural powder with Almond Milk, banana, chia seeds and honey - delicious. I love it so much I take it away with me on holidays otherwise my day just doesn't feel the same. Recommend this to everyone whether it be for training or losing weight.

Mr

By: on 10 December 2016
This is a good product that the contents can be trusted not to have fillers or added sugars. The pack bundle is great as I have it for breakfast so it blends well. The delivery is good and the website is easy access

NZ WPI

By: on 20 November 2016
I have just started out at the gym and was recommended this protein. I can honestly say that it tastes great (Organic Cacao Flavour) and is also affordable. Top product
(5)

Easy on the belly

By: on 11 November 2016
I use this protein every morning in my shakes. I suffer from digestive issues and find it hard to find a protein powder gentle enough. This protein is great for gut aswell as being delicious enough to mix with just plain water!! Love it.
(5)

Great taste, easy digestion!

By: on 11 November 2016
The cacao mint mixes easily, it tastes great, and is not sickly sweet like so many other brands I've used in the past. I'd recommend it to anybody!
(5)

Quality, convenience and value

By: on 10 November 2016
This product meets my high standards on quality, this is premium WPI. Not to mention the great service and value, I am very satisfied Professional Whey customer.
(5)

Best protein powder we've used!

By: on 5 November 2016
All the flavours we have tried are delicious. Vanilla is our favourite, it is delicious and isnt overly sweet like most powders we have tried. Delivery is super quick, never disappointed!!
(5)

Miss

By: on 31 October 2016
I purchased the trial pack a few weeks ago, this option is such a great idea to give new customer a chance to try out all the flavours without them spending a large amount of money on something they may not like. However im so amazed by how good this protein powder is, i love it, i use it mixed with water, in my smoothies, overnight oats and use it to make protein balls My favorite flavour would have to be the choc mint !! So bloody good!
(5)

The Best Protein Ever!

By: on 25 October 2016
I purchased NZ Whey Protein Isolate at the recommendation of my trainer and I have to say it is the best protein I have ever tried! It is delicious, clean, high quality, and is the only protein I've found that doesn't leave me with a bloated feeling. I purchased both the 1kg Vanilla (delicious mixed with water or added to my morning oats), and the multi-pack (great to taste all flavours, the choc-mint is especially delicious!). This will definitely be my protein of choice from now on! Thank you so much for creating such a fantastic product!
(5)

Super clean

By: on 24 October 2016
Over the years i have tried many brands of whey... until i found NZ. this product is clean and high quality. And for a sweet tooth like me the flavours are Delicious.
(5)

Mrs

By: on 21 October 2016
Great product !!! I am new to the whole protein thing and loved that I could test the different flavours without buying bulk. I have just reordered more delicious vanilla bean flavour. Thank you for having such an amazing easy to drink product.
(5)

Delicious and nutritious

By: on 20 October 2016
First timer trying NZ WPI. Went the safe option with 1kg cacao mint and a sample pack of cinnamon. Both flavours are delicious but cinnamon was my favourite and great to addition to cooking. Minimal ingredients and no fillers, big thumbs up and will be a return customer.
(5)

No substitute for quality

By: on 19 October 2016
I have been taking this NZ WPI for a couple of years and honestly can't find a fault. Simply a brilliant supplement! It tastes great - not artificial, is filler free and is easily digested. You may find cheaper products, but doubt you will find something that tastes as clean, is from NZ pasture fed cows and delivers great results. Cacao flavour taken with either milk or water, it's fantastic - highly recommend.
(5)

Good quality

By: on 16 October 2016
This product is of high quality and is worth its price. I have tried many brands and this is the most natural I could find. Cocoa flavour is by far my favourite
(5)

The best

By: on 16 October 2016
This protein powder ticks all the boxes for me! Mixes easily, sourced from grass-fed cows (= happy cows), no artificial flavours or sweeteners, doesn't upset my tummy (easily digestible), and it tastes delicious (like real food, not fake rubbish).
(5)

WPI for the win

By: on 5 September 2016
My trainer recommended I use this during my 12 week challenge, as its the same brand she uses. Being a big fan of choc mint, I decided to give it a go. After reading previous reviews I was sold, ordered my 4kgs and waited, wow what great service not only did Professional Whey deliver before any other company in Australia but the taste was awesome too. I am seeing great results now halfway through my challenge, and the WPI really does just taste like a Milo drink. Do yourself a favour and try it. Cheers.
(5)

Best tasting protein

By: on 5 September 2016
Finally found a good tasting protein that has low fat, low sugar and is 99% lactose free. And has great results.
(5)

Great Powder

By: on 1 September 2016
I have been using another branded protein powder and it was terrible. NZ WPI no only tastes great but easily digests.
(5)

f45 challenge winning protein

By: on 28 August 2016
One of the key switches I made half way through the F45 Challenge was from my vegan protein powder to a whey protein powder. David from Alpha Bioscan recommended I try Professional Whey and it’s easily the best protein powder I’ve ever had. I needed to retain and build muscle and the extra amount of quality protein I got from this New Zealand Whey Protein Isolate was crucial in my success in winning the challenge. The protein is sourced from pasture feed dairy cows and coupled with only 4 other ingredients including organic cacao and organic stevia, making it the cleanest, most effective protein powder you can get.
(5)

fantastic quality, purity at a realistic price

By: on 22 August 2016
I have researched and trialed many WPI products over the past year and I just love professional whey for its quality and purity - grassfed cows which is much healthier and more effective, and lack of nasties added. There is a lot of crap in some powders, and all these additives build up in the body over time. Especially when you are using a lot of stuff like me. Ie BCAAs, Beta Alanine, Ethyl L carnitine, Creatine, WPI, plus other supps. So I want as pure & natural as possible. It is also extrememly well priced when compared to coparable quality WPI from other leading brands,
(5)

The Best WPI There Is

By: on 21 August 2016
I've been using NZ WPI for a few years now and have always found it to be the best powder when you consider it's purity and quality of ingredients for the price. Whenever, I look at alternatives at a cheaper price, I keep coming back to NZ WPI because it has absolutely no additives and all natural ingredients. I highly recommend this for anyone's post-workout powder. The only thing I'd like is a little cheaper, but not if that compromises quality.
(4)

Love love love!

By: on 10 August 2016
This is an incredible brand and product. I love that it doesn't have added fillers or sugars and is completely pure! I recommend it to all my friends as not only does it not have those added fillers and sugars but it mixes well and tastes amazing! My friend is in loev with the vanilla, but my personal favourite is the cacao mint! The mint chips just add a beautiful after taste. Thanks Professional Whey!
(5)

My Favourite WPI by far!

By: on 25 July 2016
I have tried a few brands up to this point, and all have left that artificial taste in my mouth. Not NZ WPI! I am happy to report that it mixes well, is gentle on the tummy and makes a huge difference to my recovery after a hard session on weights. I love that you can purchase smaller trial packs - that helps with testing different flavour combos, and the cinnamon is especially decadent in my morning oatmeal with berries! mmmm...Which reminds me: I must jump on and order some more!
(5)

Outstanding Product

By: on 17 July 2016
When it comes to protein powders, taste and ease of mixing are nice to haves. Most importantly this product is very easy one the guts, and I have found that with both myself and my clients that rotating brands is not needed with this product as I never feel bloating or discomfort in the bowels while using it. Of course there is then the added bonus of taste and how well it mixes. Service is second to none, with my product arriving the next day every time I order. If you could mix and match flavours when ordering 15x1kg bags that would be awesome
(5)

Love it!

By: on 16 July 2016
Absolutely love this. It's super clean & it tastes like milo! It's a win for me!
(5)

Mixmaster WPI

By: on 14 July 2016
Brilliant product, I have been using it for a few years now. I purchase the natural flavour which tastes fine on its own however add a teaspoon of cocoa powder and it’s even better. When I’m more interested in putting on mass I will add some skim milk powder which is no problem for the WPI as it is so soluble with water it all mixes perfectly. Highly recommend this clean, high quality product!
(5)

NZ WPI

By: on 6 July 2016
Great clean product. Very popular at our gym. every one loves it .
(5)

Cacao mint!

By: on 1 July 2016
I've tried quite a few different protein varieties, the choc mint is hands down the best tasting one out there! I've now gone through 8kg of it and I'm not sick of it!
(5)

Cacao and cacao mint

By: on 28 June 2016
This isn't like most other protein powders I have had which are "good" or "I can deal with it"...The cacao and cacao mint are like a nice treat after a hard workout I think I'll be sticking to these flavours majority of the time.
(5)

Natural NZ WPI - who needs flavour?

By: on 16 June 2016
Before trying the Natural WPI I had tried the Organic Cacao NZ WPC. I was nervous about the taste of the natural WPI but I shouldn't have been. Mix this with water and it just tastes like weak milk. Easy to drink after a workout and no nasty aftertaste. No fake sugar taste either. Top quality and mixes well. I won't buy flavoured again and use the savings to buy more WPI!
(5)

Vanilla WPI

By: on 8 June 2016
Mixability is great! Worked best with coconut milk and still gave a rich, creamy taste. Foamed a bit with almond or rice milk but adding a bit of one of these with the coconut gave a texture like an old school malted milkshake! Delicious! Vanilla flavour was perfect to blend with chai, raw cocoa or cinnamon and honey. This product is superb quality!
(5)

vanilla WPI

By: on 6 June 2016
What I loved about this no after taste I blended powder with crushed ice Was refreshing with great vanilla taste
(5)

My favourite whey protein

By: on 6 June 2016
I've tried a lot of protein powders before and discovered this one after extensive research because I wanted my protein from grass fed cows. I love the fact that it contains less than five ingredients too with no fillers and no artificial sweeteners. I have been using NZ Whey Protein Isolate for over three years now and, despite trying other brands, I keep going back to this product because it is the best quality protein out there!
(5)

Amazed

By: on 1 June 2016
I've never really used protein powders before, I am basically ignorant but I am amazed with the impact it makes in my performance and the results. I won't be going anywhere else.
(5)

Great product, no frills

By: on 31 May 2016
After trying heaps of protein products over the years full of ingredients I didn’t need, I’ve been incredibly impressed with Professional Whey’s NZ Whey Protein Isolate. I used to be happy with just the natural flavour, but now I really enjoy the Mint Cacao flavour which tastes great in smoothies with mixed berries and coconut water/milk. Highly recommended!
(5)

Flawless!

By: on 27 May 2016
An incredibly versatile product, NZ WPI mixes into absolutely anything, i’ve used it in yogurt, milk, water, juice, healthy pancake mix and there seems to be literally nothing out there it doesn’t mix flawlessly into. As an extremely low carb/fat solution to protein powder it also has no perceivable flavor to interrupt what you may be mixing it with, it’s so natural that it is virtually tasteless, making it the perfect healthy protein additive to any of your drinks or meals.
(5)

Pure Quality WPI !

By: on 25 May 2016
I've had so many different brands of Isolate Protein and until I discovered this gem, I ended up dreading the post gym protein. This is exactly what a protein should be, no additives, no preservatives. The vanilla and cinnamon flavours aren't overpowering. Couldn't recommend this product any more, absolutely love it!
(5)

For gym and triathlon

By: on 23 May 2016
Tastes great, easy to get down after a gym workout. I've actually been using this for several years now and very happy. I'm a triathlete/cyclist who also hits the gym for weights, and it's good after a hard ride or a weights session.
(5)

Great product, great service

By: on 15 May 2016
This is the first time that I have ordered direct from this company and found it easy to use and the order was delivered quickly. I found the product was a great price and mix's well with milk. I am very happy with this product and recommend it to anyone
(5)

Reliably Leaner

By: on 8 May 2016
This product will undeniably lead to leaner results compared to other WPI's. Within 6 weeks my recovery was not only improved but so was my lean muscle mass. Will continue to use Professional Whey & recommend.

Whey protein powder.

By: on 1 May 2016
Ok so I slipped up ordering online and got the vanilla rather than the caco this time opps! But I was plsesantly surprised at the taste and flavour of the vanilla. It tasted real didn't have any gross after taste and wasn't too sweet. ( many others are). As I mix my powder with just a little coconut water I depend on it tasting good and mixing well. Bonus this powder does both. Totally happy!
(4)

Pure

By: on 20 April 2016
I love this protein because it doesn't have that sickly fake taste that lots of other brands of protein does.
(5)

Super clean

By: on 16 April 2016
Such a clean product, I don't react well with most proteins but I've had no issues with this at all, easy to mix, digest, doesn't taste synthetic in taste like most proteins, tastes fantastic. Great to find a company who cares about what they are putting into the bodies of everyone else. Great work guys keep it up!
