UC-Flex Tablet is a nutritional supplement used to maintain bone and joint health. It contains chicken cartilage powder (UC-II), vitamin C, and vitamin D. UC-II (undenatured type II collagen) helps maintain healthy joint cartilage and may support smoother joint movement over time. Vitamin C supports collagen production, which is important for maintaining strong connective tissues in the joints, while vitamin D helps maintain bone strength and proper calcium balance. It is generally used as supportive therapy and not as a prescribed treatment for specific joint diseases.
