Let’s talk about the eggshell

The inside of an eggshell is covered with a thin layer that you might have seen stuck to your boiled egg on sunday mornings. There are two membranes located between the shell and the egg white that protect the egg from bacterial invasions.

These membranes are composed of proteins, one of them being collagen. They also contain glucosamine, chondroitin, and hyaluronic acid. All of these compounds are great in treating pain related to joint and connective tissue disorders.
