That claim is misleading.
𦓠First: knees donāt ālose collagen and get fixed by eggshellsā
Your knees are joints made of cartilage, bone, ligaments, and fluid. With age or wear (like osteoarthritis), cartilage can thin, but:
- You cannot ārestore knee cartilageā by eating eggshells
- There is no medical evidence that eggshell recipes repair joints
š„ What eggshells actually contain
Eggshells are mostly:
- Calcium carbonate (similar to chalk)
They do not contain collagen in usable form for joints.
ā ļø Why eggshell ārecipesā are risky
- Can cause stomach irritation or constipation
- Risk of bacterial contamination (like Salmonella) if not properly processed
- Too much calcium can lead to kidney stones or mineral imbalance
š§ What actually helps knees and joint pain
If someone has knee pain or early joint wear (like osteoarthritis):
𦓠Evidence-based options:
- Regular low-impact exercise (walking, cycling, swimming)
- Weight management (reduces pressure on knees)
- Physiotherapy / strengthening muscles around the knee
- Doctor-approved supplements like:
- Vitamin D
- Calcium (if deficient)
- Sometimes glucosamine (mixed evidence)
ā About collagen supplements
Even collagen supplements:
- are broken down into amino acids in digestion
- do not directly ārebuild knee cartilageā in a simple way
š§ Bottom line
- ā Eggshell recipes do NOT repair knees
- ā No food ārestores collagen in joints overnightā
- ā Real improvement comes from movement, strength, and medical care
If you want, I can explain real ways to reduce knee pain naturally that actually have medical support (and are safe for older adults too).
