Why Knee Collagen Matters
Healthy knees rely on cartilage, a smooth tissue that cushions the ends of bones and allows joints to move comfortably.
Collagen is one of the main structural proteins found in cartilage.
As we age:
- Natural collagen production gradually decreases.
- Cartilage may become thinner.
- Joint flexibility can decline.
- Stiffness and discomfort may become more common.
These changes are especially common in people with osteoarthritis.
What’s Actually Inside an Eggshell?
Most of an eggshell consists of:
- Calcium carbonate (about 95%)
- Small amounts of magnesium
- Phosphorus
- Trace minerals
The shell itself contains very little collagen.
However, the thin membrane inside the shell is different.
