UC-II (Undenatured Type II Collagen)

UC-II (Undenatured Type II Collagen)

UC-II is undenatured type II collagen that keeps its triple helix. About 40 mg orally is used to induce oral tolerance for knee discomfort. Dose and mechanism both differ from gram-level hydrolyzed collagen peptides.

Low-dose oral tolerance

After contact with gut-associated lymphoid tissue, undenatured type II collagen can induce immune tolerance to cartilage type II collagen and reduce over-attack on joint cartilage. Trials often use about 40 mg daily—not collagen as amino-acid feedstock. Knee discomfort is the main setting; endpoints are usually joint-function scales, not skin elasticity.

Keep it distinct from hydrolyzed collagen peptides

Hydrolyzed collagen peptides supply hydroxyproline oligopeptides in gram amounts, as matrix feedstock and fibroblast signals. UC-II doses are two orders of magnitude lower; the triple helix must stay intact, and heat denaturation loses this tolerance path. Buy by undenatured type II labeling; ordinary collagen powder cannot replace it.
