What Does "Hydrolyzed" Collagen Mean, and Why It Matters
July 26, 2026 · 3 min read
Hydrolysis is a process that breaks large proteins down into smaller fragments called peptides, using water and (usually) enzymes. Applied to collagen, it turns a tough, fibrous structural protein into something that dissolves in liquid and can be taken as a daily supplement.
Why it matters practically
Un-hydrolyzed collagen—gelatin, essentially—needs heat to dissolve and sets into a gel as it cools. Hydrolyzed collagen peptides stay dissolved in hot or cold liquid, which is the entire reason a stir-into-your-coffee ritual is possible at all.
What "enzymatically hydrolyzed" adds
Some brands specify enzymatic hydrolysis specifically, as opposed to purely heat- or acid-based processing. Enzymatic methods are generally considered a gentler, more controlled way to break the protein down into consistent peptide sizes—part of why the resulting powder mixes as easily as it does. Unmade's peptides are enzymatically hydrolyzed down to roughly 3,000 daltons—a low molecular weight that is a large part of why a single scoop dissolves cleanly into hot or cold liquid instead of clumping.
The takeaway for reading labels
If a collagen product does not specify hydrolyzed (or "collagen peptides," which means the same thing), it may not dissolve the way you expect. It is one of the few label details worth actually checking before you buy.
