Can Eggshell Membrane Reduce Joint Pain?
BaCkGRound While many conventional treatments have been used to remedy chronic joint pain, interest continues to grow in the area of alternative, natural treatments. Eggshell membrane (EM) supplementation is a novel treatment for joint health, and has recently been shown to rapidly and continually improve joint pain in patients with osteoarthritis and joint and connective tissue disorders. The current study aimed to observe the effects of one particular eggshell membrane product (fast joint care+; FJC+) supplementation on chronic joint pain in physically active adults. METhodS Sixty adults (40.2 ± 10.2 y; 78.6 ± 10.2 kg) experiencing chronic joint pain supplemented daily with either 500mg FJC+ or placebo, over the course of 4 weeks. Participants also completed a weekly exercise protocol designed to challenge their irritated joint. Participants then rated their joint pain immediately, and one day after, this exercise challenge. RESulTS Participants in the FJC+ group reported significantly less joint pain post-exercise following FJC+ supplementation (-16.13 ± 3.60) when compared to those in the placebo group (–4.30 ± 2.84; p=0.00171). In addition, during the 4 week study, both groups experienced decreases in next day joint pain (p=0.0015), although there were no significant differences between the two groups (p>0.05). ConCluSionS In the current study, daily FJC+ supplementation appeared to decrease post-exercise joint pain vs. placebo, although this effect did not persist 24 hours post-exercise. Because eggshell membrane research is in its infancy, further research may be needed to clarify its utility in managing joint pain.

Why Study Eggshell Membrane?
in the united States, over 20% of adults have reported doctor-diagnosed joint and connective tissue (JCT) disorders; this number has been projected to increase by 40% over the next 25 years [1, 2]. numerous forms of intervention have been used as treatments to improve joint pain. Conventionally, nonsteroidal antiinflammatory drugs (nSaids) and analgesics have been used to address joint pain associated with JCT disorders; however, their long term use has been associated with diverse and severe side effects including cardiac and gastrointestinal complications [3, 4]. Alternative therapies used to treat joint pain include dietary supplements; the most popular of these supplements being glucosamine, chondroitin and methylsulfonylmethane (MSM). While many turn to these complementary treatments to avoid the side effects associated with NSAIDs and analgesics, there is little evidence to support their effectiveness, and the evidence that does exist is equivocal . Several large-scale human...
