Overview

Dymatize ISO100 is a hydrolyzed 100% whey protein isolate — meaning the protein is pre-digested (hydrolyzed) for the fastest possible absorption and is isolated to remove virtually all fat, lactose, and carbs. Each serving provides 25g of protein with less than 1g of sugar and 120 calories. ISO100 has won numerous taste awards, with Gourmet Chocolate and Birthday Cake being perennial favorites. The hydrolyzed isolate process makes it one of the most easily digestible protein powders available, ideal for those with lactose sensitivity. Dymatize has been a trusted sports nutrition brand since 1994.
