How can I tell if a product has an effective level (High-DH) of hydrolysis?
The best test is to find out the percent of di and tripeptides. A high-DH will have over 30% to 40% di & tripeptides. Proto Whey, by far the best in the market, has 50% or more di and tripeptides, which produces an AMW of less than 1,000-1,200 daltons. Just as important, a top quality high-DH, biologically-efficient protein product like Proto Whey contains low concentrations of amino acids; levels under 3-5% free form aminos. Some products attempt to deceive the consumer by reducing their average molecular weight tests by adding large amounts of free form aminos. This is not what a true high-DH hydrolysate protein is. Adding amino acids to a true high-DH product is a waste and undesirable as it could easily cause osmotic diarrhea and gas. Also, check the ingredient listing to see if free form aminos are added, and for the inclusion of whey protein hydrolysates in the number one spot (although this will not tell you the DH of the hydrolysate).
