Eggshells for Knee Collagen? Here's What Science Really Says

Why Eating Raw Eggshells Isn't Recommended

Grinding eggshells at home and eating the powder is not the same as taking a standardized eggshell membrane supplement.

Possible concerns include:

  • Bacterial contamination
  • Sharp particles
  • Digestive irritation
  • Difficulty measuring safe calcium intake

Homemade eggshell powder has not been proven to restore knee collagen.

Other Nutrients That Support Joint Health

Instead of focusing on one ingredient, experts generally recommend a balanced diet containing nutrients such as:

Protein

Protein provides amino acids that help the body build and maintain tissues.

Vitamin C

Vitamin C plays an important role in normal collagen production.

Good sources include:

  • Citrus fruits
  • Strawberries
  • Bell peppers
  • Kiwi

Omega-3 Fatty Acids

Omega-3s may support overall joint health as part of a balanced diet.

Sources include:

  • Salmon
  • Sardines
  • Walnuts
  • Flaxseed

Calcium and Vitamin D

These nutrients support healthy bones, which are important for overall joint function.
