Natural Eggshell Membrane May Help Comfort Joints
Previous research suggests that natural eggshell membrane may be a source of collagen, glucosamine, chondroitin, hyaluronic acid, and calcium, and may help improve joint health. A recent study suggests that natural eggshell membrane may help reduce pain and stiffness in people with knee discomfort.
For their study, the researchers recruited 160 participants who had experienced grade 2 or 3 knee arthritis for 1 to 5 years. The participants took 500 mg of natural eggshell membrane or a placebo daily for 30 days. After day 30, all the participants took 500 mg of natural eggshell membrane for 60 days.
Arthritis symptoms were assessed at baseline and on days 7, 30, and 90 days using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and by measuring joint range of motion.
Participants in the eggshell group saw an average 24% improvement in the WOMAC-stiffness score by day 7, which was significantly higher than the average improvement in the placebo group. The eggshell group also saw an average 22% improvement in the WOMAC-pain score. At day 30, the WOMAC-stiffness score in the eggshell group had improved by 35% and the WOMAC-stiffness score had improved by 33%.
When the researchers compared results for participants who took the natural eggshell membrane for 90 days to those who took it for 60 days, they found that 71% in the 90 day group had at least a 15% decrease in pain, compared to 53% in the 60 day group.
The study was conducted by researchers from Istanbul University. It was published online ahead of print on November 22, 2019 in the Journal of Arthritis.
