The claim “When your knee loses collagen, eggshells are a lifesaver” is not supported by strong medical evidence.A few points to know:
- Eggshells are mostly calcium carbonate, not collagen.
- Some supplements use eggshell membrane, which contains small amounts of collagen, glucosamine, and other compounds. Some studies suggest it may help joint discomfort, but the evidence is limited and it’s not considered a proven treatment for knee problems.
- Knee pain can have many causes, including Osteoarthritis, tendon injuries, ligament injuries, or inflammation. Simply consuming eggshells is unlikely to restore lost cartilage or collagen.
If you’re considering using eggshells:
- Raw eggshells can carry bacteria if not properly sterilized.
- Large or sharp pieces can be a choking hazard or irritate the digestive tract.
- Excess calcium intake can be harmful for some people.
For maintaining joint health, evidence generally supports:
- Regular strength and mobility exercises
- Maintaining a healthy weight
- Adequate protein intake
- Getting enough vitamin D and calcium
- Following medical advice for underlying joint conditions
If you’d like, I can also explain what is known about eggshell membrane supplements and the research behind them.
