We are always looking to bring D-Cal to the next level. We addressed the issue of joint mobility, but the concern of inflamed joints also arose. Adding Curcumin C3 Reduct™, a standardized extract obtained from the turmeric plant, to our D-Cal formula is our solution to those concerns. By adding C3 Reduct ™, a more bioavailable form of curcumin, this curcumin tablet is then able to support a healthy inflammatory response and joint function. Now you can stay active for longer, while increasing your bone strength too!
