What is collagen? 
Collagen is an essential protein It is present in common areas of the body such as nails, connective tissues, including tendons, hair and skin. It is the basic pillar of the infrastructure of our body, the cement that binds and builds all these components, forming 7% of our total body mass, this includes 10% of the lungs, 4% of the liver and nothing less than 67% of cartilage.

If we have a sedentary life, the problem is that the entire area of ​​the kneecap is not well covered with collagen, so if we do not move or try to exercise, we will immediately notice pain when rubbing against the bones in a bad way.
In addition, as we get older, the body absorbs collagen from the alimentos, and this produces the effects of aging, wrinkles, loss of elasticity in the skin and pain of various kinds.
