Whey protein hydrolysate is a concentrate  powder produced from whey agglomerated with sunflower lecithin in which some of the amino bonds have been broken by exposure of the proteins to heat, acids or enzymes. This pre-digestion makes hydrolysed proteins more rapidly absorbed in the gut than either whey concentrates or isolates.

• Whey protein hydrolysate appears to enhance the effects of carbohydrate ingestion on post-exercise muscle glycogen resynthesis.
