🦴 What actually happens in the knee
- Joint cartilage breaks down over time (age, injury, inflammation, weight, genetics)
- The body does use collagen (collagen) as part of connective tissue
- But digestion does not send “knee collagen” directly to the knee
🥚 What about eggshells?
Eggshells contain mostly calcium carbonate, which is sometimes used in supplements. However:
- They are not a source of collagen
- There is no strong clinical evidence that eating eggshell powder rebuilds knee cartilage
- Poorly prepared eggshells can carry contamination risk
So the claim “eggshell is the solution” is not medically supported.
🧪 What actually helps joint health
1. Nutrients that may support joints
- Protein (supports tissue repair)
- Vitamin C (needed for collagen synthesis)
- Omega-3 fatty acids (anti-inflammatory support)
- Adequate calcium and vitamin D (bone health)
2. Evidence-based options for knee issues
- Strength training / physiotherapy (very important for Osteoarthritis)
- Weight management (reduces joint stress)
- Pain relief or anti-inflammatory medication if prescribed
- In some cases: injections or surgery
3. Collagen supplements
Some studies suggest collagen peptides may modestly help symptoms in some people, but results vary and they don’t “regrow cartilage overnight.”
🧠Bottom line
- Knees don’t “run out of collagen” in a simple way
- Eggshell is not a solution for joint repair
- Real improvement comes from mechanical support (muscle), nutrition, and medical care when needed
