Stiff Knees? Take Some Gelatin, Study Suggests


In the study reported in Dallas, men and women with symptoms of mild osteoarthritis of the knee were first evaluated for knee pain, stiffness, mobility, flexibility, and joint strength. They were then assigned at random to receive either a placebo or gelatin with calcium and vitamin C. The evaluations were repeated at eight and 14 weeks into the study.

The researchers found that there was a significant improvement in all pain, stiffness, and mobility measures across testing sessions for all subjects in both groups. People who ate gelatin, however, showed significant improvement compared to others for certain strength and work performance tests, "particularly those tests which challenged the joint structure the most," the researchers noted.

McAlindon tells WebMD that just taking 60 mg of vitamin C per day -- in addition to the amount already in the diet -- significantly reduces the risk for osteoarthritis progression. He notes that in his study of diet and osteoarthritis, people who ate the most vitamin C daily had a several-fold reduction in their risk for osteoarthritis progression, and the difference between the lowest third and middle third was just 60 mg. "So it wasn't a big increase; it was like taking an extra orange a day," he says.

As of this writing, there have been no reports about whether the same treatment effect could be seen with orange-flavored Jell-O. Stay tuned to this channel.
