Muscle Matrix

Superior blended protein formula to help maximize muscle recovery and growth.

  • 55% Whey Protein Isolate & 45% Micellar Casein blend
  • Provide muscles with an advanced fast- and slow-digesting protein
  • Anti-catabolic protein formula that can release amino acids for up to 7 hours
  • Contains a full-spectrum amino acid profile to maximize muscle recovery
  • The perfect blend of protein sources to be used both day and night


Muscle Matrix contains 25 grams of pure, complete protein derived from two different milk sources that digest and absorb at different rates to ignite muscle protein synthesis and keep amino acid levels elevated for several hours. The benefit of prolonged amino acid absorption is that it helps keep you in an anabolic state — maximizing muscle growth and repair while minimizing muscle breakdown.

The whey protein isolate used in Muscle Matrix is rapidly digested and causes an almost immediate rise of amino acid levels in the blood that remains elevated for around 1.5 hours and then returns to baseline after approximately 3-5 hours. You then have the micellar casein found in the protein matrix that coagulates in the gut and is digested slower than whey protein isolate. This leads to a slow and steady release of amino acids into the blood that can remain elevated for up to 7 hours — drastically extending and amplifying muscle protein synthesis and your anabolic state.

Together, the whey protein isolate and micellar casein in Muscle Matrix provide the ideal and perfect times to help support muscle recovery and growth.



Muscle Matrix contains no low-quality whey concentrate or other inferior proteins, added carbs, maltodextrin, dextrose, creamers, or any other fillers — just pure, cold pressed, cross flow micro and ultra-filtered non-denatured protein to help maximize muscle recovery and growth.


If you want the fastest muscle recovery possible to get you back in the gym and support muscle growth, you need a full amino acid spectrum consisting of BCAAs and EAAs. Muscle Matrix contains both in their naturally occurring forms, which can also help prevent muscle breakdown.


Don’t cheat your gains by using inferior protein sources. NutraBio Muscle Matrix combines two of the highest-quality protein sources to provide your muscles with 25 grams of protein per serving to support muscle growth while also helping you reach your daily protein intake.


Slow muscle recovery can lead to less muscle growth and more frustration. Muscle Matrix is the perfect foundation for your muscle-building temple by laying the framework to effectively rebuild and repair broken-down muscle fibers from intense training sessions.

Key Ingredients

Whey Protein Isolate

This specific WPI90 source is a CFM low temperature, cross flow ultra and microfiltration source of protein to ensure it is of the highest purity possible. Whey protein isolate is a protein powder made from whey, a byproduct of cheese production. It’s a high-quality, easily digestible protein source that is low in fat and carbohydrates. The benefits of whey protein isolate include muscle building and repair, weight loss support, and improved overall health and wellness.

Micellar Casein

This is another form of protein that is derived from milk. Only this specific source is known as a slow-digesting protein, meaning that it releases amino acids into the bloodstream at a much slower rate than other types of protein. Due to its slow release, micellar casein is a popular choice for use before bed, as it can provide a sustained release of amino acids to support muscle recovery and growth during sleep when normally you would be in a fasted state, and catabolism may set in. Micellar casein is also commonly used in protein blends to help individuals stay full longer and extend the release of amino acids to support muscle recovery and growth.
