Which of all types of collagens is specific for joint health?

Joint health has become a public concern due to the high incidence of joint discomfort and mobility restrictions in the oldest populations. Joints are complex structures mainly made up of cartilage, which predominant component is type II collagen. Therefore, research efforts were focused on finding a solution to improve joint mobility and discomfort, positioning native type II collagen as a leading ingredient. Several clinical studies carried out showed its efficacy and safety compared to placebo and even to the standard clinical treatment of chondroitin sulphate and glucosamine chloride. And to top it all off, it can be included in functional foods to make its consumption more accessible to everyone.
