Whey Protein Isolate (WPI)

Bulk Nutrients' Whey Protein Isolate (WPI) comes from grass fed, hormone (rbST) free cows. It 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.

Dosage

30 grams (approximately 1 level scoop) after training for maximum nutritional benefit, or anytime during the day for a low fat meal replacement.

Directions for Whey Protein Isolate

Combine powder with 300-400ml of water or low fat milk and consume immediately.

    Very efficient service. I love the product and the price. Only hassle is the snap lock closure can take a concerted effort to close properly.

    Whey Protein Isolate Banana Flavour

    Posted by Keeni on Nov 10, 2018

    I purchased this one for my husband to try as I’ve been using Bulk Nutrients products for some time now. He was reluctant at first due to the low price and plain packaging, but surely that’s a good thing no?
    Well he loves it! Loves the banana flavour, says it’s not too overwhelming or too sweet, and is so easy to drink! Loves it in his oats too...overall win!

    Great in the shaker after a workout

    Posted by Tara on Nov 07, 2018

    I'm not usually a fan of protein shakes made with water in the shaker but I have enjoyed this one after my gym sessions or as the occasional out and about snack. Mixes well in the shaker and tastes good. Goes too fluffy and doesn't taste right in the blender when making a smoothie so will keep for the shaker. Will be buying again.

    WPI Awesome

    Posted by Winnie on Nov 05, 2018

    First time buying WPI this year and it is flawless. The macros are perfect and the quality and flavourings are A+. Haven't bought WPI/WPC anywhere else in a very long time.

    Super versatile

    Posted by Tania on Oct 23, 2018

    I am super happy to have found this WPI! As a family of multi users this is the perfect fit!
    We all have different tastes and uses for it so being unflavoured is such a bonus as well as the fact it mixes well and just does what it is suppose too.
    And that fact we can add it to our foods and it is not detected by young ones helps as well!
    Well done Bulk!!
