Collagen supplement makes worn joints less stiff and painful

Study

Mexican researchers from the Universidad Autonoma de Nuevo Leon traced 5 previously published trials in the scientific literature in which subjects with worn joints were given collagen supplements. The trials mainly focused on wear in the knee joint.

In 3 of the 5 trials, subjects were given hydrolyzed collagen, usually in a dose of 10 grams per day. In the remaining trials, subjects were given collagen in the form of peptides or undenatured type II collagen.

The trials lasted 10 to 48 weeks.

More details about the trials are given in the table below. Click on it for a larger version.

Results
In the trials, researchers determined the severity of complaints using the standardized WOMAC questionnaire. The higher the score, the more complaints. Collagen supplementation reduced the total score, according to the figure below. Click on it for a larger version.

The WOMAC questionnaire looks at multiple aspects. Collagen supplementation significantly improved joint stiffness scores. You can see this above.

Another part of the questionnaire involves subjects having to indicate on a 10-centimeter line how much pain they have in the worn joint [VAS]. You can see below that supplementation reduced that pain by about 2 centimeters.
