COMPLETE 40:40:20 MEAL REPLACEMENT SHAKE
NutraBio Muscle Matrix MRP is a comprehensive meal replacement formula designed to provide your body with the ideal blend of critical macronutrients, vitamins, and minerals to help you meet your nutritional needs and satisfy hunger. Developed using a 40:40:20 ratio of proteins to carbs to fats and a patented fiber compound, Muscle Matrix MRP supports muscle growth and repair, replenishes glycogen (energy) stores, enhances lipolysis (the speed at which fats are broken down), and helps keep blood glucose levels in check. On the surface, it may seem like Muscle Matrix MRP is no different from any other meal replacement product on the market today, but nothing could be farther from the truth. What puts Muscle Matrix MRP in a class of its own and makes it the #1 rated meal replacement product on SupplementReviews.com are where the macronutrients are derived from, its clean profile, and the lack of unneeded fillers. Take a look at Muscle Matrix MRP's fully transparent label and you will find:

13 grams of Whey Protein Isolate - Gram for gram the purest form of protein available (90% pure protein). Whey isolates are rapidly digested and cause robust increases in hyperaminoacidemia (elevated amino acid levels in the blood) that remains elevated after 1.5 hours and returns to baseline after approximately 3-5 hours. These elevated levels increase protein synthesis and anabolism.
12 grams of Micellar Casein - Micellar casein coagulates in the gut and is digested slower than whey protein isolate. This leads to a slow increase in amino acid concentrations in the blood that remain elevated for up to 7 hours, thus prolonging muscle protein synthesis. The combination of isolates and casein in Muscle Matrix MRP work together at the right times to help you achieve results.
16.5 grams of Highly Branched Cyclic Dextrin (HBCD) - Not your typical carbohydrate; HBCD has a high molecular weight and ultra-low osmolality. The result is a carbohydrate that replenishes muscle glycogen stores and provides smooth, constant energy without spiking blood sugar levels or causing gastric distress.
9 grams of Medium-Chain Triglycerides (MCTs) - Considered a "healthy fat," the MCTs found in Muscle Matrix MRP are derived from coconut. Studies have shown the MCTs can increase metabolic rate and the speed at which fats are broken down to release fatty acids into the bloodstream to be used as energy. This may lead to improvements in body composition.
4 grams of Fibersol®-2 - A digestion-resistant maltodextrin, Fibersol2® helps support intestinal regularity and does not alter healthy, steady-state glucose or insulin levels. What's more, Fibersol2® has been clinically demonstrated to delay post-meal hunger and increase the satiety hormones PYY and GLP-1 that help tell your brain that you are full.
Full Spectrum Vitamin and Mineral Profile - Considered essential nutrients, vitamins and minerals act in unison to perform hundreds of vital roles in the body, such as bone formation, wound healing, and strengthening the immune system. They also convert food into energy and repair cellular damage. The vitamin and minerals found in Muscle Matrix MRP may help supplement micronutrient deficiencies found in a regular diet.
When you're pressed for time and still trying to stick to your diet and training regimen, it can be tough to find something that satisfies your hunger needs that still provides everything you need to meet your macros. Muscle Matrix MRP offers a healthy, convenient meal replacement choice or snack for the on-the-go fitness enthusiast who doesn't have time to sit down and eat but still wants a filling, nutritious option without all the junk typically found in unhealthy and unappetizing fast foods, snacks, or substandard meal replacement products. Muscle Matrix MRP contains no fillers, amino spiking, excipients, dextrose, added sugar or carbs, artificial colors, GMOs, or banned substances. Only the most effective, research-proven, and cleanest ingredients were selected by NutraBio, the most trusted name in sports nutrition, to create the premier meal replacement product on the market today.

Muscle Matrix MRP is much more than a standard meal replacer or snack; it is a nutrient dense, finely balanced combination of high-quality functional ingredients designed to support your training, diet, and efforts to build a better body.

The Science Behind NutraBio Muscle Matrix MRP
A closer look at the ingredients used to make NutraBio Muscle Matrix MRP, the premier meal replacement product on the market

A Quick Word About Milk Proteins as a Whole
Extensive research on milk proteins (whey and casein) has been conducted as it relates to their roles in enhancing adaptations from exercise. This research has shown that milk proteins, ingested following exercise and throughout the day, can speed recovery, promote a positive nitrogen balance, increase glycogen replenishment, and improve hydration status- ultimately leading to increases in skeletal muscle hypertrophy and neuromuscular strength. When compared to other protein sources, milk proteins have the highest PDCAAS (Protein Digestibility Corrected Amino Acid Score) and contain the greatest density of leucine (whey 11%; casein 9.3%), the primary branched chain amino acid responsible for stimulating muscle protein synthesis. While both whey and casein are high in quality, they do differ extensively in the rate they digest, which offers a unique benefit to individuals when they are combined together.

WHEY PROTEIN ISOLATES... The Fuel that Ignites Muscle Protein Synthesis
Whey protein isolates digest and absorb rapidly and are, gram for gram, the purest form of protein available (90% pure protein). This level of purity is achieved through a cold cross-flow micro- and ultra-filtration process that removes the larger, less-absorbable protein molecules while also filtering out the fat, lactose, and ash that can be present in whey concentrates and substandard protein powders. Furthermore, this process does not denature the valuable proteins and peptides in whey, so the protein itself is of a higher quality.

Studies suggest the ingestion of fast-acting protein sources, such as whey isolates, can increase amino acid levels in systemic circulation and stimulate robust increases in protein synthesis, arguably the most important physiological factor in existence when it comes to muscle growth, strength, and recovery. What's more, since whey protein isolates generally are low in carbs, lactose free, fat free, cholesterol free, and gluten free, it makes them the perfect choice for low-carb dieters, lactose intolerant individuals, or athletes who want to get ripped while packing on muscle.

MICELLAR CASEIN... The Fuel that Sustains Muscle Protein Synthesis
While whey isolates digest and absorb quickly, micellar casein digests and absorbs more slowly. Because it is digested slowly and leads to a relatively sustained increase in amino acids, micellar casein seems to inhibit protein breakdown to a greater extent than whey protein isolates and prolongs muscle protein synthesis (MPS).

It should also be noted that not all casein is equivalent. Micellar casein, as opposed to caseinate, is isolated from milk by filtration rather than by use of acid or heat. This filtration method preserves the structural integrity of the protein. When heat or acid is used to separate casein out of milk, the micelle's structures are altered, resulting in a loss of biological activity and digestibility. It's not surprising then that undamaged milk proteins, such as micellar casein, provide more than just a source of amino acids. It also provides many biologically active proteins that have direct immune and physiological benefits. This is why micellar casein and not an inferior casein was used as the slow digesting protein in Muscle Matrix MRP.

WHEY ISOLATES + MICELLAR CASEIN = A powerful one-two punch for igniting and prolonging muscle protein synthesis
From the above information, it is not hard to see that when whey isolate and micellar casein are combined into one formula, such as in Muscle Matrix MRP, gym-goers, athletes, and fitness enthusiasts alike can reap the benefits of both proteins. On the one hand, whey isolate ingestion leads to a rapid spike in amino acids levels, which increases muscle protein synthesis more than micellar casein. On the other hand, micellar casein tends to have a more anticatabolic effect than whey isolates and prolongs muscle protein synthesis to a greater extent. The combination of the two means greater increases in lean muscle mass and shorter recovery times compared to when they are ingested separately.

In fact, a 2006 study conducted by Kerksick et al. examined the influence of a fast protein source (whey) compared to a blend of fast and slow proteins (whey and casein), ingested post-exercise over a 10-week period of resistance training. Subjects who ingested the blend of fast and slow protein showed significantly greater increases in muscle mass (+1.8 kg) than those who ingested only the fast protein.

HIGHLY BRANCHED CYCLIC DEXTRIN... A Performance Enhancing Super Carb
Carbohydrates have been cast in a negative light the past few years with so-called experts stating they cause weight gain, excess body fat, negative blood lipid profiles, and a host of other problems that can wreak havoc on our health (all of which are simply not true). However, what these experts fail to tell you are that carbohydrates are the preferred source of fuel during anaerobic exercise, such as sprinting or weight lifting. Adequate carbohydrate consumption, broken down into glucose in the bloodstream or stored in muscle tissue as glycogen, ensures you have the stamina to power through your workouts without hitting a wall. In fact, various professional fitness organizations recommend 50-60% of total daily calories should come from carbohydrates in order to produce optimal performance in athletes. On the other hand, inadequate carbohydrate consumption can cause your body to use protein as energy, which in turn affects the ability of muscle to repair and recover. Simply put, carbohydrates are king when it comes to exercise performance. It should be noted though that not all carbohydrates are created equal. This is why NutraBio formulated Muscle Matrix MRP using the patented super carb ClusterDextrin®.

Unlike a typical carb such as dextrose or sucrose, ClusterDextrin® is a low glycemic, highly branched cyclic dextrin (HBCD), which has a high molecular weight and ultra-low osmolality. This property of HBCD makes it highly soluble a
