About Protein Blends

Whey protein blends usually consist of a mix of Whey Protein Concentrate, Whey Protein Isolate and Micellar Casein (milk protein isolate). These proteins are combined so that the user benefits from the positives of all three proteins.

The most prominent benefit of combining the three proteins is to take advantage of their absorption rates. WPI and WPC are rapidly absorbed proteins which contain high levels of branched chain and essential amino acids, while Micellar Casein is a slowly absorbed protein which is low in fat and over 80% protein. In combination they make a blend great to use at all times of the day.

Why Bulk Nutrients Recommends Protein Matrix Plus?

Protein Matrix+ has been designed to compete squarely with the biggest brands in the world. It combines some of the most pure forms of protein available anywhere in ratios that are perfect for muscle growth and recovery. Our blend also includes additional Glutamine for its recovery benefits, not just cheap amino fillers.

So why buy Protein Matrix+?

  1. It’s up to 83% protein (very high for a blend)
  2. High in BCAAs (essential for muscle recovery)
  3. Low in fats and carbs (just the nutrients you need)
  4. The Micellar Casein is made in Australia and by purchasing you support Aussie families
  5. Read Our customers love for PM+ in the reviews section.

In short: when you buy Protein Matrix+ you can be sure that you’re saving money, not compromising on quality, and supporting Australians just like you.

Designed for optimal results both after training and as a general all purpose protein powder

Protein Matrix+ combines whey protein concentrate and Australian made milk protein isolate with whey protein isolate, all being from grass fed cows. These proteins are rich in natural levels of EAAs and BCAAs and are generally considered the best available for muscle growth and recovery. Protein Matrix+ is further complemented by additional glutamine, Glutamine is an amino acid essential for recovery.

A protein powder that reduces bloating and is easily digested

While lactose is often an issue for those consuming whey proteins, Protein Matrix+ includes a special lactase enzyme which minimises issues for those who have lactose problems (such as bloating and gas), meaning even very sensitive people who can usually only tolerate WPI, can drink it without issue.

Protein Matrix+ has one of the highest protein levels of any blend on the market, with Protein Matrix+ Vanilla having a protein level of 83%. Protein Matrix+ is absorbed quickly so it can be consumed at any time of the day, after training or as a general use protein.

Great tasting, creamy texture

Protein Matrix+ is the closest you’ll get to a creamy milkshake taste in a protein shake! It’s delicious!

The best protein if your lactose intolerant, great flavours aswell.


Posted by Felix Scerri on December 30, 2019

A good product. Its taste is slightly sour when dissolved in water, but that is only a minor issue. It works well.

I have (literally)tried almost every shake on the market and I would not go back to any of them. Bulk Nutrients shake – Protein Matrix and Thermowhey – taste great, mix well and fill the gaps! their customer service is also one of the best I’ve ever dealt with.

I’ve recently switched to Protein Matrix after previously using WPC.
I found that after a few days use of WPC I had a sore stomach and had to take a break for a few days.
Since switching to Matrix and having a shake every day I’ve had no issues at all. It mixes well and tastes delicious. If WPC gives you any stomach issues this is a great replacement at a good price. Highly recommend!!!

Sure a good protein powder. Mixes really well in smoothies and porridge and has a great flavour

At first I was sceptical as I always preffered a wpi over a blend but my last 2 shipments have only been matrix. I find a good combination of ingredients in it, my wife whose a bit fussy likes it too (I’m only saying a bit fussy incase she reads this but truthfully speaking she is hella fussy). It’s easy to drink, taste good and no bad reaction on its way out. :) thank you.

Great low calorie protein option

The new Chocolate Fudge flavour is simply rich and delicious – so good it’s really best on its own!


Posted by Jeanette on September 21, 2019

Just got the Salted Caramel & Lemon Cheesecake after trying and loving the Choc Honeycombe. All the flavors are delicious , sweet and creamy without tasting chemically, and don’t give me tummy issues at all despite generally not tolerating dairy very well.

great protein powder

Posted by Shin on August 31, 2019

I had a normal protein powder before from other brand and I had a difficulty with a digestion of the protein powder as I am slightly lactose intolerance.
I have no problem at all with this product and very easy to mix with water. The taste great as well.
