About this supplement

Hydrolyzed whey protein is a predigested form of whey protein where the long protein chains (peptides) have been broken down into shorter chains and individual amino acids through enzymatic hydrolysis or acid hydrolysis. This process enhances its digestibility, absorption rate, and reduces its allergenic potential compared to intact whey protein. It is derived from whey, a by-product of cheese production, and is rich in branched-chain amino acids (BCAAs) like leucine, isoleucine, and valine. It is commonly used in sports nutrition for muscle protein synthesis, recovery, and as a general protein supplement. In topical beauty products, it can function as a humectant, film-forming agent, and may provide conditioning benefits to skin and hair.

Physical properties

Typically a fine, off-white to cream-colored powder. Hygroscopic (absorbs moisture). Soluble in water, forming clear to slightly opaque solutions. The degree of hydrolysis affects molecular weight, taste (often bitter), and solubility.

How it’s made

Produced by subjecting whey protein concentrate or isolate to enzymatic digestion (using proteases like trypsin or pepsin) or acid hydrolysis under controlled conditions of temperature and pH. This breaks peptide bonds, creating smaller peptides and free amino acids. The hydrolysate is then filtered, purified, and spray-dried into powder.
