For many people over 60, maintaining strong bones, healthy joints, and good mobility becomes increasingly important. Everyday activities such as climbing stairs, standing from a chair, walking around the neighborhood, or exercising can become more difficult when muscle strength declines or joint problems develop.
This has led to growing interest in eggshells as a natural source of calcium. Eggshells are largely made of calcium carbonate, which means they contain a substantial amount of calcium. However, that does not mean eating eggshell powder can suddenly transform someone who struggles to walk into a daily runner.
The good news is that calcium really is important for normal bone health and muscle function. The key is getting it safely and combining it with the other nutrients and lifestyle habits that support healthy aging.
If you want to experiment with eggshell powder as a food ingredient, preparation and hygiene are extremely important. Raw eggshells can carry harmful bacteria, so simply collecting shells, crushing them, and eating them is not a good idea.
Start by saving clean eggshells from properly handled eggs. Rinse them thoroughly to remove remaining egg residue. Place the shells in a clean pan or on a baking sheet and heat them thoroughly to reduce the risk of bacterial contamination. Allow them to cool completely before grinding.
Once completely dry, the shells can be ground into a very fine powder using a clean spice grinder or another suitable kitchen appliance. The powder should be extremely fine because larger pieces can be unpleasant to consume and may irritate the mouth or throat.
However, homemade eggshell powder has an important limitation: the exact amount of calcium in each homemade serving is difficult to determine. This makes it difficult to know precisely how much calcium you are consuming.
For that reason, eggshell powder should not automatically be treated as a replacement for a properly formulated calcium supplement or a balanced diet. Taking excessive calcium can also cause problems, particularly for people with certain medical conditions or those taking particular medications.
A safer strategy for most older adults is to obtain calcium primarily through foods. Dairy products such as milk, yogurt, and cheese can provide significant amounts of calcium. Calcium-fortified plant milks, tofu made with calcium, certain fish eaten with their bones, and some leafy green vegetables can also contribute to calcium intake.
