About this supplement
Hydrolyzed Whey Protein Isolate is a predigested form of whey protein isolate where the protein chains have been broken down into smaller peptides and amino acids through enzymatic hydrolysis. This process enhances digestibility, absorption rate, and reduces allergenicity compared to intact whey protein. It is derived from milk whey, which is the liquid byproduct of cheese production, and undergoes extensive filtration to remove most lactose, fat, and carbohydrates, resulting in a product that is typically >90% protein by weight. The hydrolysis creates a mixture of di-, tri-, and oligopeptides along with free amino acids, making it rapidly bioavailable and often less likely to cause gastrointestinal discomfort.

Physical properties
Typically a fine, off-white to cream-colored powder. Hygroscopic (absorbs moisture). Soluble in water, forming a clear or slightly opaque solution. May have a slightly bitter taste due to hydrolysis. Molecular weight distribution varies based on degree of hydrolysis.
How it’s made
Produced by first isolating protein from whey via microfiltration, ultrafiltration, or ion exchange to remove lactose, fat, and minerals. The resulting whey protein isolate is then subjected to enzymatic hydrolysis using proteases (e.g., trypsin, chymotrypsin, or bacterial/fungal enzymes) under controlled temperature and pH conditions to break peptide bonds. The process is halted by heat inactivation, followed by filtration to remove large particles and sometimes debittering steps. The final product is spray-dried into powder.
