So, can eggshells cure knee collagen loss?

The honest answer is:

No.

While eggshell membrane supplements may offer mild joint-support benefits for some people, raw eggshells themselves are not a proven cure for damaged cartilage or collagen loss.

The viral claim is exaggerated and oversimplified.

The most effective approach to healthy knees still includes:

• Good nutrition
• Regular movement
• Weight management
• Proper medical care when needed

Bottom Line

Natural remedies can sometimes support wellness—but they should be approached with realistic expectations and basic safety in mind.

When it comes to your joints, long-term care will always matter more than quick internet fixes.
