UC-II (undenatured type II collagen) is a bioactive collagen derived from chicken sternum cartilage that maintains its native triple-helix structure. It works through oral tolerance mechanisms in gut-associated lymphoid tissue to reduce joint inflammation and preserve cartilage integrity.
Reported Benefits (Provisional)
Origin & History
UC-II Collagen is derived from chicken sternum cartilage and is processed to preserve its undenatured form, which is believed to be more effective for joint health.
Research Narrative (Provisional)
Clinical trials have shown that UC-II Collagen can significantly improve joint comfort and flexibility compared to placebo and glucosamine-chondroitin combinations.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
UC-II Collagen (Undenatured Type II) is a highly specialized bioactive ingredient derived primarily from chicken sternum cartilage, standardized to deliver specific functional compounds rather than broad macronutrient content. A typical efficacious dose is 40mg per serving. Protein content: UC-II is protein-based, with undenatured type II collagen comprising approximately 25-30% of the 40mg dose (~10-12mg active collagen). Key bioactive compounds include chondroitin sulfate (approximately 5-10mg per 40mg serving), hyaluronic acid (trace amounts, approximately 1-2mg), and glucosamine (minor amounts inherent to the cartilage matrix). The critical distinction of UC-II is its undenatured (native) triple-helix structure, which is preserved through low-temperature, low-pressure processing — this structural integrity is essential for its oral tolerance mechanism via Peyer's patches in the gut-associated lymphoid tissue (GALT). Bioavailability note: Unlike hydrolyzed collagen (which requires gram-level dosing of 5-10g), UC-II exerts its effects at 40mg due to immunomodulatory activity rather than direct substrate provision; it does not meaningfully contribute to daily protein, carbohydrate, fat, caloric intake, or micronutrient status. No significant vitamins or dietary minerals are present at functional concentrations in a standard 40mg dose. Fat content is negligible (<1mg), carbohydrates are negligible, and caloric contribution is essentially zero (<1 kcal per serving).
Reported Mechanism (Provisional)
UC-II collagen activates oral tolerance pathways when processed by Peyer's patches in the small intestine, generating regulatory T-cells that specifically target type II collagen. These Tregs migrate to synovial joints and suppress inflammatory cytokines like TNF-α and IL-1β while promoting anti-inflammatory IL-10 production. This targeted immune modulation reduces cartilage degradation by inhibiting matrix metalloproteinases (MMPs) that break down collagen.
Clinical Narrative (Provisional)
A 120-day randomized controlled trial with 52 participants showed UC-II (40mg daily) reduced joint discomfort by 33% compared to placebo. Another study comparing UC-II to glucosamine plus chondroitin found superior improvements in joint flexibility and daily activities. Most trials are relatively small (50-200 participants) with short durations, though results consistently favor UC-II over placebo. Evidence quality is moderate, with more large-scale, long-term studies needed.
