Additional Information

Ultramyosyn Whey Isolate contains protein that is processed using microfiltration to ensure an isolated whey that contains a minimum of 90% protein with minimal lactose and fat. These isolation processes separate the valuable protein from non-protein materials yielding a highly-purified whey isolate.

>>Enhanced with additional free-form amino acids to work synergistically with Whey Isolate's high concentration of aminos to support recovery. >>State-of-the-art manufacturing processes are used to retain the active Whey Protein Peptides and Microfractions including Beta-lactoglobulin, Alpha-lactalbumin, Lactoferrin and more - some other whey isolate processing methods remove Glycomacropeptides, which are an important protein component. ~Delivers a high quality Whey Isolate protein with a higher amino acid profile gram for gram than ordinary Whey Concentrate.
