NutraBio Muscle Matrix Chocolate Peanut Butter Bliss Has Arrived!

NutraBio is known for complete transparency, third party testing, and unmatched quality. Mark Glazier, CEO and founder of NutraBio, started the company back in 1996 and he quickly learned that in order to do things right, he had to build his own facility. Fast forward 20 years later, NutraBio is one of the most well-respected brands in the industry, and they continue to progress, expand, and build.

The amazing Chocolate Peanut Butter Bliss is now available in Muscle Matrix!

NutraBio spent nearly all of 2019 formulating, testing, and releasing several products in delicious new flavors. You can see all of the news on our NutraBio News/Articles page, for there are several. But today, we cover their most underrated protein powder, Muscle Matrix. We last talked about it nearly a year ago, when the incredible Muscle Matrix Strawberry Pastry flavor came out. But now it’s time for a unique flavor update that NutraBio fans already know and love:

Muscle Matrix Chocolate Peanut Butter gets a Blissful upgrade!

One of the most interesting 2019 releases was Chocolate Peanut Butter Bliss, which launched in both Classic Whey and 100% Whey Protein Isolate. This flavor quickly became a fan favorite since NutraBio was able to pull off an incredible chocolate peanut butter flavor without using peanut flour — meaning it’s nut allergen-free! After receiving feedback, the team decided to move it to a third protein powder here.

Muscle Matrix is a unique blend of 55% whey protein isolate and 45% micellar casein, which supplies your muscles with a steady stream of amino acids for up to 4 hours. It’s the perfect ratio of fast and slow digesting proteins to put you in anabolic state and keep you there!

About the flavor: Chocolate Peanut Butter Bliss

Check out this blog post to see where Chocolate Peanut Butter Bliss got it’s start!

While NutraBio’s chocolate peanut butter flavors were good, the brand’s master flavor formulator, Michael Perez, decided it was time for an upgrade. It came by way of the new and improved Chocolate Peanut Butter Bliss flavor system. Michael’s goal was to take a unique spin on this classic flavor, so don’t expect the same old boring chocolate peanut butter – NutraBio made sure this one really stood out!

Nut allergen free!

What’s most impressive is that Michael was able to create Chocolate Peanut Butter Bliss without using any peanut flour, meaning people with nut allergies can enjoy it! That’s something we’ve never seen before, and he did a phenomenal job — so it’s no surprise they’re adding the flavor to the Muscle Matrix line-up!

Muscle Matrix Macronutrient Profile

We argue that NutraBio is the most transparent company in the supplement industry, and their labels say it all. With every serving of Muscle Matrix, it lists the exact amount of each ingredient, even the flavor profile!

Although it’s more common now to see companies list the protein source and percent yield, to see them list how much sucralose or flavoring they use is very rare. That just shows how NutraBio has nothing to hide and they strongly believe that the consumer should know exactly what they’re putting in their body, without compromise.

Check out that ingredient panel! Complete transparency as always!

Furthermore, NutraBio never uses any fillers, excipients, proprietary blends, maltodextrin, or low-quality protein sources!

Here’s what one serving of Muscle Matrix has to offer:

  • Calories: 120

  • Protein: 25g

    • Composed of 14.19g of Whey Protein Isolate and 10.81g of Micellar Casein

  • Carbohydrates: 2g

    • Sugar: <1g

  • Fat: 0.5g

Muscle Matrix has some very solid macronutrients, and it’s incredibly clean. We’re still not quite sure how they are able to keep the calories, sugars, and fats that low, but still deliver a strong and sweet flavor. You can tell it was specifically formulated to crush cravings and help build a respectable physique!

Muscle Matrix Ingredients

Let’s kick off this section by discussing the two protein sources that keep you in an anabolic state for nearly four hours!

  • Whey Protein Isolate – 16.31g (Yielding 14.19g of Complete Protein)

    NutraBio Whey Protein Isolate Line-up

    Looking for a pure whey protein isolate, then NutraBio has you covered!

    Whey protein isolate (WPI) is a high quality protein source derived from milk, and it makes up 55% of the protein blend. WPI is at minimum 90% protein by weight and is known for being low in lactose, fat, and sugars. WPI digests rapidly and is a great source of all nine essential amino acids and is specifically rich in leucine.

    It’s typically recommended to take whey protein pre or post workout in order to quickly spike muscle protein synthesis (MPS) to help with recovery and growth.

    WPI is incredibly effective and one of our top protein sources, however if you can’t eat another meal for four or more hours, then you may want to consider adding in a slower digesting protein source to keep MPS elevated for longer, which is where casein comes into the picture!

  • Micellar Casein – 13.35g (Yielding 10.81g of Complete Protein)

    Micellar Casein is also a high-quality protein source that’s derived from milk and it makes up 45% of Muscle Matrix’s protein blend. Just like WPI, casein contains a good amount of essential amino acids, is low in sugars, fats, and carbs, but it digests much more slowly.

    NutraBio Classic Whey Pistachio Delight Graphic

    Pistachio Delight is one of NutraBio’s latest flavor creations! But it only comes in Classic Whey.

    Once the casein enters your digestive system, the protein molecules will coagulate together, which takes the body longer to break down. Therefore, WPI is commonly referred to as an anabolic protein source and casein is called an anti-catabolic protein source.

    This just means while WPI spikes MPS rapidly to put you in an anabolic state, casein will keep MPS elevated for longer. It’s the perfect post workout combination to fuel muscle growth and recovery!

  • Other Ingredients – Flavor, Mixability, and Consistency

    MC and WPI are the two main components of Muscle Matrix, however in order to make it taste like a dessert, NutraBio has to use a few extra ingredients. They vary slightly based on the flavor, but here’s what you can expect to see:

    • Natural Flavors

    • Sweeteners: Sucralose and Ace-K

    • Sunflower Lecithin

    • Xanthan Gum

    • Salt

    That’s a short list compared to many other protein powders on the market, but NutraBio still delivers on the flavor! The extra ingredients are included to create the delicious flavor, add creaminess, and make sure the mixability is on point. They keep it as minimal as possible to give you the most pure product on the market, which we really appreciate. And the fact that their label is fully disclosed takes them to the next level.

Available Flavors

This article was mainly focused on the new Chocolate Peanut Butter Bliss flavor, but Muscle Matrix also comes in several other delicious options! One of our favorites is Strawberry Pastry, which was released last year! And it’s not your typical plain strawberry… it has strong notes of a “buttery crust” flavor, along with an incredibly smooth texture that puts it over the top!

NutraBio Muscle Matrix is now in the fantastic Strawberry Pastry flavor system!

Here’s an updated list of all Muscle Matrix available flavors:

    It will be interesting to see how it turns out with Muscle Matrix, since it has a good amount of casein protein, which helps create a thicker consistency. If you like a thicker and slower-digesting / more satiating protein shake, then Muscle Matrix is a must-try!

    Final Thoughts: Muscle Matrix Is The Ultimate Protein Blend!

    Muscle Matrix Chocolate PB Bliss

    The ultimate protein matrix now comes in Chocolate Peanut Butter Bliss!

    NutraBio has a phenomenal line of protein powders, including Classic Whey, Micellar Casein, 100% Whey Protein Isolate, and Grass-Fed Whey Protein Isolate. But in our opinion, their most underrated protein powder is Muscle Matrix! It’s fairly common to see protein blends on the market, but they practically never fully disclose the exact amounts of protein used.

    For example if a protein blend lists: whey protein concentrate, whey protein isolate, and micellar casein, without knowing the amounts, you could be getting 95% whey protein concentrate with just the other two sprinkled in. That’s an easy trick to pull off in the supplement industry, and the companies are just trying to cut costs the majority of the time. But lucky for you, NutraBio is here to save the day and showcase the value of transparency!

    Not only are you getting a phenomenal product, you can trust what’s on the label is in the bottle, because NutraBio supplies 3rd-party lab tests on all products!
