NO palm oil, NO maltodextrin, NO xanthan gum, NO carrageenan, NO erythritol, NO xylitol and free form amino acids. ONLY 100% Whey Protein Isolate by cross-flow ultrafiltration and microfiltration. Microfiltration is the most expensive process of those used for the isolation of protein supplements based on whey proteins, but it is also the one that is best at preserving the integrity and the presence of bio-active protein fractions, which determine the quality of the protein. The whey proteins have a biological value and naturally contain branched-chain amino acids (BCAA). The isolated whey protein (WPI, Whey Protein Isolate) is the purest form of whey. Yamamoto Nutrition Iso-FUJI 100% NATURAL contains whey protein isolated by cross-flow ultrafiltration and microfiltration. Microfiltration is the most expensive process of those used for the isolation of protein supplements based on whey proteins, but it is also the one that is best at preserving the integrity and the presence of bio-active protein fractions, which determine the quality of the protein. The whey obtained in the first stage of processing by ultrafiltration is carried by an apparatus that, using a membrane filter system, proceeds with further progressive filtration, through which other unwanted particles are eliminated, including minerals, lipids and lactose. The microfiltered proteins are 99% undenatured and retain all the important bio-active peptide fractions of undenatured whey. Iso-FUJI 100% NATURAL contains whey proteins isolated by cross-flow ultrafiltration and microfiltration, it does NOT contain collagen with other elements that alter the quality or the biological value of the product.
