Product Description

Whey Protein Isolate

Our Whey Protein Isolate (WPI) is a low temperature cross and ultra filtered whey protein which remains completely undenatured. We believe it is one of the purest Whey Protein Isolates on the market, with high levels of protein and lower levels of fats, carbohydrates and sodium. Our Whey Protein Isolate is naturally rich in amino acids, particularly branched chain amino acids (BCAAs), essential amino acids (EAAs) and glutamine which ensures optimum muscle growth.

We use the strongest sweetener available and only the finest flavouring systems in our flavoured whey protein isolate, which ensures an exceptionally pure finished product. Our flavouring systems are mixed between 1% and 4% which guarantees product purity.

Our Whey Protein Isolate is suitable for those who want the fastest absorbing and most bio available protein source. From endurance to strength athletes users will find our Whey Protein Isolate (WPI) helps recovery, strength and muscle levels as well as strengthening the immune system.

Over the last 6 months supply for our NZ WPI has been increasingly unsteady.

Providing a consistent product is very important to us so we are now transitioning to cold filtered, grass fed WPIs from Ireland and the US.  

These proteins have undergone lengthy testing and as a positive the protein content is fractionally higher than our previously used NZ WPI, with equally low fat and carbohydrate levels.

Most importantly the whey used from both suppliers is cross filtered WPI from grass fed cows, identical to the process used with our previous NZ WPI.

You may notice some very minor changes in taste and texture but you can rest assured our WPI remains extremely pure, and of the highest quality as our customers expect.

  • Does the trick

    Posted by on May 10, 2017

    Once again Bulk Nutrients delivers. This WPI is affordable and comes in a wide variety of flavours. Mixed with water or milk, the taste is great. No bloating or nasty after taste. Delicious.

  • Super tasty!

    All the flavours I have tried so far have been really tasty especially the choc honeycomb one. The powder mixes well, ordering is easy and delivery is super quick.

    Not a protein expert but really like supporting Australian business, especially in an internationally dominated market such as this one. The prices on the products are amazing for what you are getting and I can't stop sending people to check it out. I was on the banana flavour first time around (tastes like banana paddlepops) and have topped up another with choc honeycomb this time too. The honeycomb is actually delicious, goes amazing in my banana/oat smoothies, just on it's own or with a bit of coconut milk. Really light, easy on the stomach and no thick, heavy feeling afterwards. I'm converted :)

    After a fair bit of research on the local Aus protein suppliers (support Aus economy), I decided to go with BN for variety in flavours and for reputation as they have a more transparent testing system in place. Also the grass fed cow source was important to me.

    Only been drinking this for 4 days and so far no bloating or stomach cramps that I have gotten with other large US brands, even with enzymes mixed in.

    I bought 5 kilos and ordered Chocolate, Choc Mint, Choc Honeycomb, Salted Caramel and Coffee but have only tried Choc Honeycomb, Salted Caramel and Coffee so far. The coffee's not bad tasting but not so strong in 250ml of water and has no caffeine (if you are looking for that morning coffee replacement). The other 2 flavours are a bit sweeter. Choc honeycomb is kind of like a crunchie chocolate bar but not so sweet or chocolatey and the salted caramel is not that salty and was really nice blended with banana and mixed berries.

    Packaging is in simple 1kg resealable bags that all have seemed to have the scoops at the top (nothing more frustrating that having to dig for a scoop).

    So far I would recommend based on being great value for money, 100% Australian and being easy on the gut.

  • Top quality raw WPI 4.5/5*

    Posted by on May 08, 2017

    First time buyer, big fan of this product. It's hard to find raw supplements that don't contain artificial sweeteners or any other nasties that damage your microbiome. When you're drinking two shakes a day this really important for overall health. Harder still, is to find one that is high quality without paying a fortune.

    This WPI is high quality as my results have continued, if even slightly improved since I changed from a competitor. Of course raw products don't taste great but that's the trade off for a healthy lower intestine. If you absolutely must consume it raw due to some misguided, ultra low carb diet you're on, mix it with water and expect a slightly peppery taste which is tolerable.

    This supp is easily made tasty with your choice of natural sweetening carb sources like blueberries and banana (my post workout go-to) and if you must, a little honey.

    If you're looking for a top quality additive free product look no further. I've had no issues with mixability or the packaging as per some reviews below.

    To make this 5 stars I'd like to see the product tested for any antibiotics that might have snuck into the supply chain at random, a few times a year (or even certified organic status). The likelihood is low with grass fed cows but I'd gladly pay an extra few bucks each time to be safe in this knowledge.

    4.5/5 stars.

  • Not the best

    Posted by on May 08, 2017

    First time trying this product and I have found the reseal on the bag doesn't work and the bag itself is too small to fit your hand into. Product itself is fine, and tasty...but you will require a secondary means of storing it

  • Best protein powder!

    Posted by on May 08, 2017

    My husband and I couldn't live without this stuff. Makes staying on track nutritionally so easy. Thanks Bulk!

  • 1 of the best

    Posted by on May 07, 2017

    Been using supplements for 15 yrs and the Bulk Nutrients is among the best WPIs I have used in terms of quality (87-91% Pro), cost, taste & mixability.
    Choc Honeycomb the pick for me but by a variety of flavours each time to mix it up..

  • Pretty good so far!

    Posted by on May 03, 2017

    Bought the chocolate isolate, it's pretty palatable with water but phenomenal with skim milk, inexpensive too! Would def be buying from here again!

  • Reviewing Raw WPI

    Posted by on May 03, 2017

    For the price, it's probably the best you can get. Its mixability is not perfect but good enough. Having a raw option is great so you don't drink that sucralose sweetener which can be real harmful on everyday use. I'm lactose intolerant but this one doesn't create a major impact. Plus digestibility of it is way better than vegan options - sorry vegan folks but it's true. Wish they put enzymes into their vegan options.

    Hope they'd make Australian certified organic option with Tassie cows.
