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

You’ve probably seen claims like this:

👉 “When your knees lose collagen, eggshells are the solution.”

It sounds simple. Natural. Even logical.

But is it actually true?

Let’s break it down—clearly and honestly.

🧠 What Happens When Knees “Lose Collagen”?
Your knee joints rely on cartilage, a smooth tissue that allows bones to glide without pain.

Collagen is a key part of that cartilage.

As you age:

Collagen production slows down
Cartilage becomes thinner
Joints may feel stiff, painful, or inflamed
This is often linked to conditions like osteoarthritis.

🥚 Why Eggshells Are Being Talked About
Eggshells are mostly made of:

Calcium carbonate (about 95%)
Small amounts of proteins and minerals
There is also a thin membrane inside the shell (called the eggshell membrane) that contains:

Collagen
Glucosamine
Chondroitin
👉 These are compounds linked to joint health.
