Synopsis

Source of validity: Scientific
Rating (out of 5): 3

Eggshell, particularly in the form of eggshell membrane, has gained attention in recent years for its potential to support joint health. The eggshell membrane is a thin layer between the eggshell and the egg white, and it contains naturally occurring compounds such as collagen, hyaluronic acid, chondroitin sulfate, and glucosamine—components often found in joint-support supplements.

Several randomized, double-blind, placebo-controlled clinical trials have investigated the effects of eggshell membrane supplementation on joint pain and stiffness, primarily in individuals with osteoarthritis or exercise-induced joint discomfort. Studies such as Ruff et al. (2009, 2012) and others have reported statistically significant improvements in pain, stiffness, and range of motion after daily supplementation with eggshell membrane for 4-8 weeks, compared to placebo. The mechanism is thought to be related to anti-inflammatory effects and the promotion of cartilage health provided by the membrane's bioactive compounds.

However, while the evidence is promising, it is not as extensive or robust as for other joint-support ingredients like glucosamine sulfate or chondroitin sulfate. Most studies are relatively small, short in duration, and conducted by or in association with supplement manufacturers. Nevertheless, the available evidence does provide moderate scientific validation for using eggshell membrane to support joint health, warranting a mid-level rating of 3 out of 5 for scientific support.
