Hybrid Ratio Isolate - Ion-Filtration Technology

IsoNatural employs a unique protein extraction technology called HRI. A hybrid of two isolate purification technologies incorporated at a specific ratio to produce a truly superior ultra-pure Whey Protein Isolate. Cutting-Edge Hybrid-Ratio Ion-Filtration (HRI) Technology allows IsoNatural to retain an exceptionally high protein yield while maintaining bioactive whey fractions. IsoNatural contains absolutely no whey concentrate. Concentrates have higher levels of fat and sugars with a lower percentage of protein and lower bioavailability than Isolates.

Pure, Natural & Intact Whey Protein Isolate Fractions
57.0% Beta-Lactoglobulin
21.0% Alpha-Lactalbumin
15.0% Glycomacropeptide
4.8% Bi-Peptides & Tri-Peptides
