Collagen is a protein that is important for our body. It ensures the cohesion and elasticity of connective tissues such as tendons, connective tissue and bones. The production of collagen decreases drastically after your thirties, making you vulnerable to injuries and other issues. You can improve the tendon with hydrolysed collagen, a very easily soluble and absorbable protein. By using collagen supplements, your tendons will recover faster after intensive exercise.
