About this supplement

Whey protein hydrolysate is a pre-digested form of whey protein where the protein chains have been broken down into smaller peptides and amino acids through enzymatic hydrolysis or acid hydrolysis. This process mimics natural digestion, resulting in faster absorption, reduced allergenicity, and improved bioavailability compared to intact whey protein concentrates or isolates. It is commonly used in sports nutrition for rapid muscle recovery, in medical nutrition for patients with impaired digestion, and in cosmetic formulations for skin hydration and barrier function. The degree of hydrolysis (DH) determines the peptide size distribution and functional properties.

Physical properties

Typically a fine, off-white to cream-colored powder. Hygroscopic. Soluble in water, forming clear to slightly hazy solutions. May have a characteristic bitter taste due to hydrolysis. Molecular weight distribution varies with degree of hydrolysis.

How it’s made

Produced by subjecting whey protein concentrate or isolate to enzymatic digestion (using proteases like trypsin, chymotrypsin, or bacterial enzymes) or acid hydrolysis under controlled conditions (temperature, pH, time). The process is then stopped, and the hydrolysate is filtered, purified, and spray-dried into powder. The degree of hydrolysis is controlled to achieve desired peptide profiles.
