If you’ve spent any time on social media, you’ve probably seen claims like:
“When your knees lose collagen, eggshells are the solution!”
While eggshells are not a miracle cure for joint pain or collagen loss, they do contain important minerals that may support bone health when used safely and appropriately. Let’s separate fact from fiction and explore how eggshells can be used as part of a healthy lifestyle.
What Are Eggshells Made Of?
Eggshells are composed primarily of calcium carbonate, the same form of calcium found in many supplements. They also contain small amounts of:
- Magnesium
- Phosphorus
- Potassium
- Trace minerals
Some research suggests that the thin membrane lining the inside of eggshells contains naturally occurring compounds such as collagen, glucosamine, and chondroitin, which are often associated with joint health.
However, eating eggshells will not instantly restore collagen in the knees or reverse arthritis.
Potential Benefits of Eggshell Powder

Calcium is essential for maintaining strong bones, especially as we age.
2. May Support Joint Comfort
The eggshell membrane contains proteins and compounds that may help support joint function in some people.
3. Affordable Source of Minerals
Instead of throwing eggshells away, some people use them as a natural calcium source.
