Cold-Pressed
Cold-pressed describes a manufacturing approach that avoids high temperatures during whey processing to preserve the native structure of the protein, including its bioactive peptides and undenatured immunoglobulins.
Why It Matters
Heat is the enemy of native whey protein. High-temperature pasteurization and spray drying can denature delicate peptides like lactoferrin and immunoglobulin G, which may have immune-supporting properties beyond pure amino acid delivery.
Cold-pressed whey is processed below roughly 50 degrees Celsius. Brands that market this method usually pair it with grass-fed sourcing and minimal additives. The protein costs more, but proponents argue you are getting a more complete biological product, not just amino acids in powder form.
How to Spot It on a Label
Front-label terms include cold-pressed, cold-processed, undenatured, native, and minimally processed. The ingredient deck should be short: whey protein isolate or concentrate, lecithin, natural flavors. Avoid products that claim cold-pressed but list dozens of additives.
