Amazentis proprietary urolithin A, also known as Mitopure, can significantly improve the mitochondrial health of healthy human knee joints and osteoarthritis knee joint chondrocytes. A mouse model of surgically induced osteoarthritis was used to test Urolithin A's ability to prevent cartilage breakdown, block inflammation, and reduce pain. After surgery, the knee develops cartilage erosion in the femur and tibia, including loss of the articular cartilage lining (superficial area). The mice were given control diet or a diet supplemented with 50 or 250 mg/kg urolixin A for 8 weeks after surgery. After 8 weeks of treatment, urolixin A significantly reduced the OARSI score (lesion severity and percentage of affected area of the entire knee joint) and circulating levels of metalloproteinase 3 (MMP3).Urolithin A prevents cartilage breakdown in a model of surgically induced osteoarthritis. Urolithin A treatment for 8 weeks after surgery induced osteoarthritis showed a protective effect on chondrocytes, reducing cartilage damage and promoting joint cell survival. Urolixin A also helps relieve the pain of osteoarthritis
UA (500 or 1000 mg/day for 4 months) significantly increased muscle strength expressed as average peak torque in the hamstring muscle and the maximum torque during knee flexion when compared to placebo. We observe clinically meaningful improvements with Urolithin A on aerobic endurance (peak oxygen oxygen consumption [VO2]) and physical performance (6 min walk test) . Levels of plasma acylcarnitines and C-reactive proteins are significantly lower with Urolithin A, indicating higher mitochondrial efficiency and reduced inflammation. This study highlights the benefit of Urolithin A to improve muscle performance.
