That claim is not medically valid.
🧠Why this is misleading
“Knee loses collagen, so eggshells fix it” is a social-media myth. The knee joint doesn’t “repair itself” by eating eggshells.
Your knee cartilage issues (like in osteoarthritis) involve complex changes in joint tissue, inflammation, and wear—not something that can be reversed by a single food.
🥚 What about eggshells?
Eggshells are mostly:
- Calcium carbonate
Some supplements use processed eggshell membrane extracts, but:
- They are not a proven treatment to rebuild knee cartilage
- At best, they may provide small support for bone health, not cartilage regeneration
- Eating raw or ground eggshells at home is not recommended (contamination risk)
🦴 Real science on knee and cartilage health
Cartilage is supported by:
- Regular low-impact exercise (walking, cycling)
- Weight management (reduces joint load)
- Physiotherapy (strengthens muscles around knee)
- Anti-inflammatory diet patterns
Some studied supplements include:
- Collagen peptides
- Glucosamine
- Chondroitin sulfate
But even these:
- may help symptoms slightly in some people
- do not regenerate cartilage overnight or dramatically
🚨 Bottom line
- Eggs or eggshells do not “restore knee cartilage”
- No food works as a “lifesaver” for joint degeneration
- Knee health improves through long-term movement, strength, and medical care
