Yamamoto Nutrition Iso-FUJI is a dietary supplement with a whey-protein basis isolated by cross-flow ultrafiltration and microfiltration Volactive Ultra Whey XP quality. It is suitable for athletes who engage in strenuous physical activity. Proteins contribute to the growth and maintenance of muscle mass. The product is enriched with vitamin B6, which combats fatigue, and the natural digestive enzyme bromelain. The whey proteins contain branched-chain amino acids (BCAA). The isolated whey protein (WPI, Whey Protein Isolate) is the purest form of whey. Microfiltration is the most expensive process for the isolation of protein supplements with a whey-protein basis, 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 ultrafiltration is carried by an apparatus that, using a membrane filter system, proceeds with further progressive filtration, through which other unwanted particles, including minerals, lipids and lactose, are eliminated. The microfiltered proteins are 99% undenatured and retain all the important bio-active peptide fractions of undenatured whey. Iso-FUJI does NOT contain collagen with other elements that alter the quality or the biological value of the product.
