The amino acid L-Proline, while famous for its power to heal all connective tissue injuries, also strengthens the heart, in addition to the joints, tendons, and cartilage. Because it’s an essential component of collagen, L-Proline is critical for maintaining youthful skin, as well as for helping repair muscle, connective tissue, and all forms of skin damage – thus minimizing the effects of aging. Without an adequate supply of L-Proline, joints and tendons will not function properly, nor will the heart muscles be as strong as they can be. Taking Proline along with Dr. Dane’s Super C Complex is a great way to promote healthy connective tissue.
