Eggshells for Knee Collagen? Here’s the Truth You Need to Know

 These are compounds linked to joint health.

 The Problem With the Viral Claim

Here’s the important part:

 Eggshells themselves are NOT a direct cure for joint collagen loss
 Grinding and eating eggshells is not a proven medical treatment
 The body doesn’t simply turn eggshell powder into knee cartilage

While calcium is good for bones, it doesn’t directly rebuild joint cartilage.
