All Natural Whey from MRM provides an optimal source of whey protein by combining an ultrafiltered, low temperature processed whey protein concentrate with cross flow microfiltered whey protein isolate. These specialized processing systems ensure a High Biological Value (HBV) protein source in the form of short and long chain peptides to increase protein retention and biological activity. All Natural Whey is also remarkably high in Branched Chain Amino Acids (BCAAs), which are the most required amino acids needed to replenish muscle stores that are utilized during strenuous exercise. The Next Generation Protein -. The biochemists at MRM have taken protein supplementing to the next level without the worry of wasting ingested protein. The addition of NitroZyme helps breakdown long and short chain peptides into smaller, more readily absorbable amino acids for maximum absorption and retention. NitroZyme helps the body release more amino acids directly into the muscles to increase muscle size, strength and lean body mass. Added L-Glutamine - All Natural Whey also contains 1g of L-Glutamine (in addition to naturally occurring L-Glutamic acid) per serving to increase recovery time following exercise. Supports Immune Health - Specific characteristics of whey proteins have shown an ability to support immune health. All Natural Whey protein contains high amounts of cysteine and other substrates used in the synthesis of Glutathione. Glutathione is a major antioxidant and supports immune health.
