Connective Tissue

Most bone protein is collagen, making glycine important not only for soft connective tissue but also for bone structural integrity. Arteries are almost entirely collagen-based, making glycine quality critical to arterial health. Cartilage loss and joint degeneration may have glycine shortage as a deeper contributing cause, beyond mechanical wear and tear alone. The article describes a mismatch between rapid strength gains and slower connective tissue reinforcement as a cause of tears and acute injuries. The article says connective tissue may not adapt fast enough to sudden large increases in muscle recruitment force. Reported consequences include torn hamstrings and acute lower-back muscle tears. Rapid muscle gain is cited as an example of connective tissue being outpaced by muscular growth. Limited glycine supply may increase tendon susceptibility to injury, particularly under stress. Bone broth and collagen are useful for healing leaky gut because they supply collagen-related building blocks needed by the gut lining.
