Collagen is a huge molecule — far too big to absorb whole. Whether a supplement has been hydrolysed is the single biggest factor in how much actually reaches your skin, hair, nails and joints. Here’s the difference, and what the studies say.
Native, non-hydrolysed collagen is an enormous triple-helix protein. Your gut can’t absorb a molecule that size intact — it has to be broken down first. Non-hydrolysed sources (like gelatin) also dissolve poorly, especially in cold liquids, and give your digestive system a lot more work to do before any of it becomes usable.
Hydrolysis uses enzymes to pre-cut that giant protein into short chains called collagen peptides — typically just a few amino acids long. This does two useful things: the powder becomes highly soluble (it mixes into water without clumping), and the small peptides are absorbed far more efficiently. Researchers have even detected specific collagen-derived peptides such as prolyl-hydroxyproline (Pro-Hyp) in the bloodstream after people take hydrolysed collagen — direct evidence that the fragments survive digestion and circulate.
The clinical work that shows benefits for skin elasticity and hydration, and for joint comfort, has overwhelmingly used hydrolysed collagen peptides — not raw gelatin. Randomised, placebo-controlled trials have reported improvements in skin elasticity and hydration over 8–12 weeks of daily collagen peptides. That’s the form with the evidence behind it.
One important distinction for the truly curious: a separate ingredient called undenatured type II collagen (UC-II) is used at very small doses for joints and works through an entirely different, immune-based mechanism. It’s not the same thing as the type I & III peptides used for skin, hair and nails — so don’t compare their milligrams directly.
For skin, hair and nails, the relevant building blocks are type I and type III collagen. Our formula uses hydrolysed bovine collagen peptides (type I & III) so you get the soluble, absorbable form that the research actually supports — not a big number of something your body can’t use.
“Hydrolysed” isn’t marketing — it’s the processing step that makes collagen soluble and absorbable, and it’s the form used in the trials that show results. Look for hydrolysed type I & III peptides for skin, hair and nails.
For absorption, yes. Hydrolysis breaks collagen into small peptides that dissolve easily and are absorbed efficiently. The clinical studies showing skin and joint benefits have used hydrolysed collagen peptides.
Type I and type III collagen. Our formula uses hydrolysed bovine collagen peptides providing type I and III.
Yes. Studies have detected collagen-derived peptides such as prolyl-hydroxyproline (Pro-Hyp) in the blood after intake, showing the fragments survive digestion and circulate.
