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 the reviews to the right! Our customers love PM+

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!
