for maintaining normal bones, muscle contraction, and many other functions.
But the knee is much more complicated than a bone surrounded by calcium.
A healthy knee includes bone, cartilage, ligaments, tendons, muscles, synovial fluid, and other tissues working together. Eating additional calcium cannot simply direct the body to send that calcium into damaged cartilage.
This is why it is useful to separate bone nutrition from cartilage repair.
Eggshell vs. Eggshell Membrane: They Are Not the Same Thing
This is perhaps the most important point.
The hard outer eggshell is predominantly a calcium source.
The very thin membrane found immediately inside the shell is different. Eggshell membrane naturally contains proteins and structural components, including forms of collagen and compounds associated with connective tissue.
Commercially processed eggshell-membrane supplements have therefore been investigated in small studies involving joint comfort and stiffness.
Some findings have been encouraging, but the evidence remains limited. Thesestudies do
