Native Whey Protein is arguably the cleanest and least processed whey protein available. Due to the process used to create Native Whey, it has unique functional and compositional properties compared to traditional cheese whey. Native Whey contains an inherently high concentration of the branched-chain amino acid, leucine, which is probably the most important amino acid for human physiology and performance. Leucine is the anabolic trigger that stimulates the body's natural insulin release and promotes protein synthesis, leading to increased muscle mass and strength. Leucine is also higher in the amino acids: tryptophan and cysteine. Tryptophan increases serotonin, which promotes endurance during exercise. Cysteine ​​is a precursor to the body's most abundant and naturally occurring antioxidant, glutathione.
