Which is better, calcium UC-Ⅱ bone collagen tablet or Tomson Bianjian R collagen chondroitin calcium tablet? Which one should I buy for joint pain?

Both products have the function of repairing joints, but the calcium UC-ⅱ collagen tablet is composed of UC-ⅱ patent, calcium and vitamin D, which can remove damaged and exfoliated chondrocytes, repair articular cartilage injury, relieve inflammation and enhance the toughness of bones. Tomson Bejian R collagen chondroitin calcium tablet is a combination of calcium, chondroitin sulfate and protein, which can increase bone density and repair joints. If the joint hurts, I think Calch UC-ⅱ is more suitable ~
