Modified amino acid found almost exclusively in collagen
We rank Hydroxyproline by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
Hydroxyproline is a modified amino acid, which is a building block used by the body to create proteins. It is found almost exclusively in collagen, the main structural protein that provides strength to skin, bones, and connective tissues.
While it is a key part of collagen, standalone supplements of this ingredient are not commonly used for general joint or skin health in humans. It is more frequently used in specific research settings or as a marker to measure how much collagen is breaking down in the body.
To create the supplement, manufacturers typically extract it from natural collagen sources, such as animal hides or connective tissues. The raw material undergoes a process called hydrolysis, where it is broken down using water and heat or enzymes to isolate the specific amino acid. The resulting liquid is then purified and dried into a stable powder for use in capsules.
This ingredient is generally mid-range in price. This is because the extraction process from collagen sources is more involved than the production of basic amino acids, but there is enough available supply to prevent it from becoming a luxury-priced item.
