We provide full label/ingredient disclosure on our Muscle Matrix protein. No games, no tricks... just the purest, freshest protein available. Inferior sources of protein such as low quality whey concentrates. Extra added amino acids like taurine or glycine used by some brands to boost nitrogen content and fool you into thinking you are getting more protein than you really are. Ion exchange or acid treated protein which destroys the natural undenatured state of whey causing it to lose its anti-cancer and immune stimulating activity. Fillers, excipients, maltodextrin or dextrose, added sugar or carbs, artificial colors, GMOs, or banned substances. Banned substances 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 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 combined together. A closer look at 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 micro and ultra-filtration process that removes the larger, less-absorbable protein molecules while also filtering out 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 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 it the perfect choice for low-carb dieters, lactose intolerant individuals, or athletes who want to get ripped while packing on muscle. A closer look at 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) times. 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, unlike what occurs in other processing methods. Basically, 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 for the slow digesting protein in Muscle Matrix. Whey Isolates + Micellar Casein = A power 1,2 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; gym-goers, athletes, and fitness enthusiasts alike can reap the benefits of both proteins. On 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 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. Which Protein Blend is the Best? Undoubtedly you have seen other protein blends on the market that not only contain whey isolates and micellar casein, but also other sources of protein such as egg, whey concentrates, and whey hydrolysates. The theory behind using these additional proteins in a blend is it will cause a fast, medium, and slow release of amino acids into the bloodstream and be more "effective" in stimulating muscle protein synthesis (MPS). Independently, each is a good source of protein (except in the case of a low quality whey concentrate) and can induce MPS, but adding them to a blend that already contains whey isolates and micellar casein provides no additional benefits according to research.
