Ultra Whey Original contains three significant muscle building ingredients: Ionized whey, Ion-exchanged whey isolate, glutamine and whey peptides. This unique formula promotes the best possible anabolic environment for muscle growth. Ionized whey is specially filtered and treated to produce a high concentration of whey peptides. Ion-exchanged whey isolate has the highest percentage of protein by composition of any manufactured whey protein. Glutamine and whey peptides can increase nitrogen retention, protein synthesis, muscle glycogen levels, enhance BCAA absorption, increases IGF-1 and can significantly decrease muscle breakdown.
