FORTIGEL hydrolyzed collagen food supplement for improving joint mobility . When Fortigel hydrolyzed collagen reaches the stomach, bioactive collagen peptides (BCPs) are absorbed and pass into the articular cartilage, where they help stimulate collagen synthesis. In addition, BCPs stimulate the anabolic phase of cartilage production and, over time, improve joint health. Thus, Fortigel hydrolyzed collagen has the potential to act at the molecular level in the cartilage metabolism process and stimulate its regeneration. It is recommended for people who lift weights, participate in repetitive or physical activities that stress the joints, are overweight, sedentary and athletes.
