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.

  • Excellent product

    Posted by on Jun 14, 2017

    Recently purchased my 5 th bag of choc honeycomb - delicious, and first bag of banana. Banana great with water or in my smoothies. Wasn't a fan of salted caramel but these 2 flavours great. Low carb, high protein, dissolve easily and satisfy my sweet cravings. I only mix with water and still taste great. Excellent quick delivery. My only criticism is the bag design. unless u can empty these into another container I find the small opening difficult to use without spilling product.

  • Wpi heaven

    Ordered the chocolate, Salted caramel and coffee, they all are absolute Yum, all WPI's have great mixability with water and they are simply great quality, affordable products. The shipping time is super quick. I have been using BN products for over 4years and highly recommend to anyone who is into fitness.

    Amazing product, great taste and super quick delivery

  • Does what it says on the tin

    Posted by on Jun 12, 2017

    I've tried several flavours including raw, vanilla, banana and chocolate. They are all delicious and they mix up so easily. With Bulk Nutrients WPI I get a good value product that does exactly what it says without all the extra ingredients (and the extra price) that I neither need nor want. I love the option of ordering in bulk and yet getting to choose different flavours.

  • Yum!

    I have found this product is really tasty, unlike other protein powders. It has no yuk aftertaste and a smooth texture.

  • Everything you could ask for in a wpi and more

    This WPI is hands down the best I've tasted the flavours are delish and it mixes so well. Not to mention the great value for money and the option to stack flavours with the 1 kg bag option you can't go wrong here.
    Well..... what are you waiting for get on it!

  • Good Quality

    great taste, easy to mix, good all round protein!

  • My new fave protein

    Posted by on Jun 08, 2017

    Finally found a delicious tasting protein that mixes easily in water. Purchased chocolate, banana & coffee & my only regret is that I didn't find your website sooner! Fast postage to remote WA, affordable prices & love supporting a Tasmanian business. Keep up the great work!

  • great value & flavour

    Posted by on Jun 08, 2017

    just tried coffee & salted caramel & they are both up to your usually very high standard.
    personally would like them to be a bit less sweet.

  • No frills, straight protein when you need it.

    Good taste, not too sweet and performs as advertised.
