SCP-II® is the next generation of joint and skin health supplementation. SCP-II® is a complex of both undenatured type II collagen and undenatured proteoglycan, the two components that make up our joint cartilage. SCP-II® is a research-based ingredient that has shown in human studies to be effective in relieving joint pain and improving mobility. It has shown in a human study to be even more effective at relieving knee pain than glucosamine, and at a much smaller dose. Proteoglycan has also shown in a human study to improve skin condition.
