Greater nutrition and health benefits than whey isolates, soy, casein or protein blends? No question! Greater nutrition and health benefits than other whey hydrolysates? Absolutely! Only Proto Whey offers a High-DH whey protein hydrolysate with higher levels of di and tri-peptides. Beware of other hydrolyzed whey products that add whole proteins or amino acids and don’t list di and tripeptide levels.
