Supplement Information

Whey Isolate (WPI) is whey protein that's been further refined to remove virtually all of the fat and lactose. The resulting product is ultra high in protein and very low in carbohydrates and fats.

This product is grass fed WPI from New Zealand.

Each serving (unflavoured) contains over 29 grams of protein and nearly 8 grams of branched chain amino acids. 

It has a pleasant, clean taste and is popular with athletes and those counting their macro-nutrients. It has a lighter, fluffier texture than whey because it contains virtually no fat. We don't add any fillers or thickeners to modify the texture.

Whey Isolate is best suited for those who suffer from lactose/digestive issues from milk (depending on the individual), or those who demand the absolute highest level of protein and lowest carbohydrate/fat level. It's generally suitable for those with lactose intolerance.

grass fed cows WPI production

Mixing Instructions

Each sachet contains one serving (31.25g). Mix entire sachet with in ~200-250ml of chilled water or milk depending on desired taste. Use a blender or hand shaker. Due to the nature of this product, it mixes best in a hand shaker without using an actuator or mixing ball.

Please note that this product is processed in a facility that also handles egg, soy, peanut, and gluten ingredients.

Very surprised but absolutely loving these samples sizes!!! My absolute favourites so far, Mixed Berry, Banana & Butterscotch Caramel. Still have a few others to try out, will come back later to review those. I have to say though, years ago, I absolutely HATED protein shakes & the gross after taste whether it be chocolate (fake gross choc flavour) or vanilla, even the thought of them, I would never ever drink them again!! But these samples sizes, perfect!! Flavours?? Amazing!! It has absolutely changed my mind about protein shakes, now I look forward to drinking them AND I can have a different flavour every day!! Loving it! One thing though, tried it first with soy milk, it changed the flavour slightly, but I prefer using oat milk, much creamier/better taste!!! THANKS HEAPS NZ PROTEIN!!!

great flavours and easy to mix, a bit frothy when shaken up, decided to go with whey instead of the isolate because of the fuller texture and price difference. The normal whey is great too 👍
Review by: Connor on Mon, Mar 31, 2025 1:10 PM
This tasted so good! Loved the butterscotch caramel and vanilla ones. Goes really well with greek yoghurt.

These are great. Absolutely love that you can purchase samples first to see if you like them first. Flavours are delicious, some alright with water some i did not enjoy. I found they were all more enjoyable with milk or oat milk and more creamier.
Review by: Tee on Tue, Feb 18, 2025 5:57 PM
Love the sample sachets! So convenient for when I’m travelling for work. They taste delicious and have a nice texture.
Great addition to smoothies, protein ‘cheesecakes’, and all sorts of other baking.
Also love how low carb they are!!!
Thanks guys 🤩

I love NZ Protein WPI, I use it to hit my protein goals and refuel after workouts daily. WPI, along with NZ Protein's EAAs and Creatine, has helped my train for and reach my goals on the World Finals stage in my sport, Firefighter Challenge, with 2x gold medals this year.
Review by: Jodi on Fri, Dec 13, 2024 1:55 PM
Tried three different samples. All three were really tasty and easy to drink.
Review by: Anonymous on Fri, Nov 29, 2024 2:26 PM
Exceeded my expectations! Great flavour and consistency. What truly amazed me was the delivery service. It was so fast I had to check they weren't manufacturing it next door! If you're looking for a quality protein powder with excellent service to match, this is it. Highly recommend.
Review by: Richard on Thu, Nov 21, 2024 3:36 PM
The chocolate caramel was delicious, will probably get the larger amount soon.
P.s the email doesn't show what flavours I'm reviewing.
Tips on how to mix the protein powder without a blender would be appreciated.
Review by: Brandon on Thu, Nov 14, 2024 1:20 PM
Fantastic flavors and the sample sizes are perfect for trying each out and having protein on hand for a busy lifestyle.
Review by: Timara on Fri, Sep 13, 2024 12:03 PM
Really tasty and goes well in baking , overnight oats and smoothies
Review by: Anonymous on Tue, Sep 3, 2024 7:33 PM
These tasted amazing. Will definitely order a full size very soon.
Fast shipping is awesome, as nothing worse waiting days for it to arrive.
Review by: Janine on Sun, Sep 1, 2024 7:56 AM
Tasted amazing! Mixed very easily and was easy on the stomach. My favourite flavour is cookies and cream
Review by: Anonymous on Thu, Aug 22, 2024 11:37 PM
Great product! Banana flavour is delicious. Easy digestion and no bloating.

Love these handy sachets. So useful for travel. Really wish you could buy more than two at a time!
Review by: Anonymous on Mon, Jul 22, 2024 12:03 PM
I got the cookies and cream flavour, it's absolutely delicious! Doesn't leave a film or weird after taste, mixes amazingly with yoghurt, highly recommend
Review by: Shelley on Sun, Apr 28, 2024 1:33 PM
Tasty, easy to use - not really sure what I was expecting but was happy with the sample. Hardest thing is choosing what flavour to order for the bigger bag!!! Was easy o mix (used the bullet and ice with almond milk), good texture - not grainy at all. Not too sweet either.
Review by: Nardine on Wed, Apr 24, 2024 8:22 AM
Great tasting product would highly recommend.
Review by: Jacqui on Tue, Apr 9, 2024 7:53 PM
Once I learnt to mix it right with 250mls of milk per scoop rather than how I'd usually make protein powder, absolutely love it! Also these guys ship so incredibly fast it's actually freaky!
Review by: Dunx on Thu, Apr 4, 2024 9:00 PM
I really like the samples, means you don't have to purchase a large quantity when you want a different flavour now and again. Other NZ samples on the market are usually vanilla, which I hate
Review by: Lyn on Sun, Mar 24, 2024 9:05 PM
Great flavours and taste but I'm still trying to work out the one I like the most so I can buy the big amount lol
Review by: Lynne on Wed, Mar 20, 2024 1:19 PM
Berry and mango are really bad and yogurt taste like vomit honest review, banana slaps 5 out of 5 NZPROTEIN REPLY: please note as we don't add agents to modify the texture, our formulations are made to mix with 200-250ml of water or milk
Review by: Anonymous on Wed, Mar 13, 2024 7:22 PM
Great product, great company. Thank you for the fastest delivery. Amazing,

Also, great protein. I’m lactose intolerant and this product works great for me. Good quality protein for muscle building

Love the product, great flavour and doesn't 'puff' me up like most dairy does. Not without effects but nothing bad enough to put me off.
Review by: Miranda on Mon, Jan 22, 2024 8:33 PM
Delicious and creamy. These sachets are great for having as a backup in your bag or at work. They also allow you to try different flavours - if that is your thing.
Review by: Viv on Thu, Jan 4, 2024 4:00 PM
Perfect size to try without wasting money of unsure
Review by: Tara on Tue, Nov 21, 2023 2:53 PM

As described. Good quality product. Yummy fkacour. Tastes great, no powdery bits, mixes in really well.
Review by: Kate on Mon, Oct 23, 2023 4:48 PM
Great product at a great price, means I can try new flavors without committing to a whole bag. Thanks!
Review by: Deanna on Thu, Aug 24, 2023 12:18 PM
Great product, will buy again. The sample packs are awesome to take away for the weekend
Review by: Anonymous on Sat, Jul 29, 2023 3:31 PM
I love the option of trying all the flavours first! They were all nice, although some better than others (vanilla and banana especially great, chocolate least favorite due to texture). I will be ordering in 1kg size now that I know my favorites.

The powder mixes really well and most flavours were enjoyable to drink, I'm having a protein shake before or after my strength training and definitely feel better for it. My kids have tried a few sips too and they think it's yummy lol.
Review by: Sabrina on Wed, Jul 19, 2023 1:45 PM
Love the sample sizes. Such a great way to get a feel for the variety of flavours before ordering your favourite in bulk. Also great if travelling.
Review by: Shannon on Sat, Jul 15, 2023 8:14 AM
A great way to try out the flavours.
Review by: Sandie on Sun, Jun 18, 2023 12:53 PM
nice flavour for my first time!
Review by: Anonymous on Wed, May 3, 2023 12:10 PM
Great flavors, personally I think the mango and mixed berry are the best for mixing into water.
Review by: Caleb on Mon, Apr 17, 2023 12:09 PM
Awesome product, sample size gives you a opportunity to try the flavor before you purchase a 1 kilo bag.
Super fast delivery, NZ protein are great.
Review by: Paul on Sun, Apr 2, 2023 3:22 PM
Tried the mango flavour as I brought a selection to take away overseas. It mixed so smooth, was not bloated afterwards, looking forward to trying the other flavours soon.
Review by: Adrian on Wed, Feb 15, 2023 1:26 PM
Great samples. I am lactose intolerant so this protein shake is just right for me. I will be buying further product
Review by: Bronwyn on Thu, Feb 9, 2023 8:38 PM
The flavour was awesome and it was Creamy and thick.
Review by: Ange on Mon, Feb 6, 2023 1:41 PM
Great tasting, not too sickly sweet like others & a good range of flavours.
Very well tolerated and def no gastro trouble like other brands. Will be reordering.
Review by: Rach on Wed, Dec 7, 2022 6:58 PM
Excellent product but will stick with unflavored to give me flexibility adding to shakes and other homemade meals/snacks.
Review by: Anonymous on Sun, Nov 13, 2022 1:12 PM
Really tasty, mixes well and is gentle on the tummy!
Review by: Debs on Mon, Oct 31, 2022 7:55 PM
Amazing flavour! Once I finish what I have I will be changing to NZ Protein
Review by: Anonymous on Thu, Oct 27, 2022 9:26 PM
The NZ Whey Isolate Sample Sample Sachets were excellent! The flavours are all great which makes it difficult to choose a favorite. The Protein is easy to mix.
I will definitely be ordering NZ Whey Isolate.

Review by: Anonymous on Tue, Nov 9, 2021 6:10 PM
I tried the vanilla and it was pretty good - i found it kept the hunger pains away until lunch! (i fast most days) will be buying again.
Review by: Julie on Fri, Apr 16, 2021 8:42 AM
The chocolate WPI had a nice flavour but was too sweet for my taste. The artificial sweetener left an after taste in my mouth.
I would have to buy another one in future.
Review by: Anonymous on Fri, Feb 5, 2021 6:51 AM
For a while range of flavours to sample and have enjoyed them all, now I need to pick one to go with! I had ordered a mint choc sample in my order which didn't arrive but otherwise very happy
Review by: Tracey on Sat, Jan 23, 2021 9:56 AM
Really liked it.

Doesn't taste chalky. Would love to sample the banana one and other flavours too before purchasing 1kg pack.

Love that WPI is low carbs compared to the other products.
Review by: Anonymous on Sat, Nov 7, 2020 6:59 AM
I've tried the Double Choc and the Gourmet Vanilla and they were sooo yum!! I'm not much of a choc fan so Gourmet Vanilla was my fave of the two. Mixes easy, I just added water and ice and shake was yum!!
Review by: Crystal on Thu, Aug 27, 2020 9:11 AM
They taste so yummy. Love the ice cream
Review by: Tracey on Fri, Aug 14, 2020 6:03 AM
This is the 2nd time I have ordered this and I really like it. I use it rarely so prefer these sample packets. Thanks for a great product.
Review by: Anonymous on Wed, Jul 22, 2020 7:14 PM
Lovely taste but was a little hard to mix in a shaker
Review by: Kelly on Wed, Jul 15, 2020 7:28 AM
I really enjoyed this product and will buy more. I don't use it very often but it is really good to have on hand for times when I need a quick meal on the run.
Review by: Anonymous on Tue, Jul 7, 2020 9:37 AM
So good. Great flavour, sample sizes are really good to try flavours out too😊
Review by: Anonymous on Fri, May 15, 2020 8:32 AM
Such a great way to 'try before you buy' and delivery was so quick!

I ordered vanilla and chocolate, chocolate was my favourite but both were nice. Texture was surprisingly creamy with just water.
Review by: Anonymous on Mon, Feb 24, 2020 8:57 AM
Tastes great, easy to mix and love that the lactose has been removed.
Review by: Ioana on Sun, Feb 9, 2020 10:13 AM
This is one of the best protein isolates I have tried to date. Great taste and mixes easily! Also being able to test the supplements via these trial sachets is so helpful. Definitely would recommend.
Review by: Seth on Sun, Jan 26, 2020 7:40 AM
Love it the best flavoured protein I have used, and low Carbs! ideal for supplement to Keto.
Review by: Anonymous on Thu, Jan 23, 2020 12:10 PM
So good being able to try a sample size sachet before committing to a big tub. Will definitely be ordering when my current protein powder runs out.
Review by: Trudi on Thu, Jan 16, 2020 11:31 AM
AMAZINGLY quick delivery and really great product, love that you can "try" before you buy - what a great idea! AND great tasting Whey Protein, the Whey Isolate was also great tasting, but not as thick as the Whey - but they do tell you this in their blurb.
Review by: Bernadette on Wed, Jan 15, 2020 7:54 AM
tasty flavours, easy to mix
Review by: Amanda on Mon, Dec 9, 2019 1:11 PM
Good Taste , a bit sweet ,
Became sticky and mushy as soon as I poured a litlle bit of milk or water
after that really hard to stir unlike the NZ WHEY , might work better with blender
It would be good to have Stevia as sweetner instead of Sucralose
NZPROTEIN REPLY: it would not be very pleasant at all if we used Stevia. Try mixing in a handshaker!
Review by: dilip on Tue, Dec 3, 2019 5:07 PM
My absolute favorite, tastes so good.
Review by: Kat on Wed, Nov 27, 2019 7:21 AM
Loved the Whey Isolate, tastes great! Hopefully it gets made in the berry and salted caramel one day :)
Review by: Jax on Mon, Sep 30, 2019 9:05 AM
tastes really good mixed with coconut milk unsweetened and ice and is low carb no sugar so fits my macros nicely

Test Reports

Here at NZProtein we always strive to be the best at what we do. We invest heavily in research and development to have innovative products and the best flavours.

We stand firmly behind our products so we have commenced periodic batch testing of products by independent third party laboratories. These test reports will provide further evidence of the standards we adhere to.

Please note that we will not be able to test every flavour due to the costs - there are simply too many flavours and various batches manufactured. For example, in the NZ Whey alone we have over 20 flavours, so it is not practicable to test every flavour in every batch but we will periodically submit samples in various flavours for analysis.
