UC-II – Forschung
Überwiegend Mechanismus / Beobachtung
15 begutachtete Studien
Was die Evidenz sagt
Überwiegend Mechanismus / Beobachtung
Die meisten Studien zu UC-II sind mechanistisch oder beobachtend statt RCTs, die einen klinischen Effekt messen — betrachte die Ergebnisse als vorläufig.
Die meiste Evidenz stammt aus hochwertigen Meta-Analysen und randomisierten Studien, veröffentlicht 2009–2026 mit einer typischen Studiengröße von 106 Teilnehmenden.
Basierend auf 15 Studien · 1 Meta-Analyse · 9 RCTs · 2,933 Teilnehmende insgesamt

Einfach gesagt: Future research should include larger trials, biomarker studies, MRI imaging, and real-world data to confirm disease-modifying potential.

An evidence-based analysis showed that undenatured type II collagen (40 mg/day) improves pain, stiffness, function, and quality of life in early-to-moderate OA (Grades 1-3), with benefits observed within eight weeks, improved compliance, and non-steroidal anti-inflammatory drug-sparing effects.
Comparative evidence favors UC-II® (Lonza Greenwood LLC, USA) over other sources, highlighting the importance of product selection.
Expert consensus recommends undenatured type II collagen as a nutraceutical adjunct with physiotherapy for long-term use in responders.
Einfach gesagt: Chondroprotectors containing CS and GS combined with UC-II are actively used in clinical practice in patients with OA and LBP as part of medicine products and pharmaconutraceuticals.

UC-II inhibits cartilage destruction at any stage of the disease through the mechanism of immune tolerance, which «trains» the immune system to be tolerant to the antigens of the destroyed cartilage.
There is ample evidence of the successful use of pharmaconutraceuticals based on CS, GS, and UC-II molecules (Chondroguard TRIO) in patients with chronic LBP due to facet joint OA.
Recent studies assessed the effect of vitamins D 3 and K 2 and their combination on OA pathogenesis.

In the WOMAC pain score, the SUCRA of passion fruit peel extract was 91% (mean difference [MD]: -9.2; 95% confidence interval [CI]: [-16.0, -2.3]), followed by methylsulfonylmethane (89%), undenatured type II collagen (87%), collagen (84%), and Lanconone (82%).
The SUCRA (99%) of passion fruit peel extract (MD: -41.0; 95% CI: [-66.0, -16.0]) ranked first in terms of the WOMAC function score, followed by Lanconone (95%), collagen (86%), ParActin (84%), and Lactobacillus casei strain Shirota (83%).
The top three total rankings are passion fruit peel extract (95.0%), Lanconone (88.5%), and collagen (85.0%).
Einfach gesagt: An RCT in healthy subjects with exercise-related joint discomfort found UC-II 40mg improved knee extension and extended pain-free exercise time.

Einfach gesagt: Conclusion The results of the study confirm the good effectiveness and safety of the Artneo combination in patients with OA of the knee joints.
Materials and methods The study included 212 patients from 12 centers in the Russian Federation, of whom 50 had radiological stage III knee OA: 41 (82.0%) females and 9 (18.0%) males aged 44 to 75.
The effectiveness of therapy was assessed by the change of pain using the Visual Analog Scale, the WOMAC index, KOOS, the EQ-5D quality of life questionnaire, and the need for non-steroidal anti-inflammatory drugs.
All patients had a complete blood count, urinalysis, blood chemistry, and ultrasonic examination of the target knee joint.
Einfach gesagt: A 90-day controlled study (n=105, ages 60-80) found adding UC-II to standard osteoarthritis care improved physical quality of life, pain, and function.
