Collagen gives our skin elasticity and makes our joints flexible. As we age, our bodies don't produce enough of this protein; therefore, we end up with arthritis, osteoporosis, and baggy skin. Collagen is the main component of ligaments, bone, teeth, and cartilage. It strengthens our blood vessels and promotes tissue development.

Degenerative joint diseases are have various causes, such as wear and tear of cartilage, which is a normal part of aging. Being overweight causes excessive stress to these ligaments and tissues.

In studying the affects of aging and other joint-related ailments, some professionals believe a balanced diet that contains protein, minerals, calcium, and vitamins C and D, contributes to joint, cartilage and tissue health.
 
There are many nutritional supplements on the market. One of the most promising is collagen hydrolysate, which is derived from animals. It appears to be most like human tissue. Research on patients with degenerative diseases has found that collagen hydrolysate has a good absorption rate and accumulates in the body.  The conclusion is that collagen hydrolysate does reach the tissue for long-lasting affect.

Studies compared collage hydrolysate to the collagen in our cells. Collagen hydrolysate stimulated the joint tissue to reproduce. This implies that collagen hydrolysate might reduce degenerative changes in joint tissue. These findings are significant because collagen hydrolysate not only reached the joint tissue, but also might also cause a positive change in the joint.
