Many people eat eggs but discard the shells, unaware of their benefits. Eggshells are “one of the cheapest and most effective natural sources of calcium,” made of about 95% calcium carbonate, plus magnesium, potassium, zinc, and iron. They also contain protective membranes rich in keratin that guard against bacteria.
Eggshells can help people with limited diets meet their calcium needs, and you don’t need store-bought powders because making your own at home is easy. While eggshells don’t directly cure or prevent diseases, they can “play an indirect role in supporting good health if used correctly.”
Bone and Teeth Health: Powdered eggshells are a natural way to “support strong, healthy bones.” Research shows they may even be absorbed more efficiently than synthetic supplements. Maintaining calcium levels can help reduce osteoporosis risk, and eggshell powder also strengthens enamel, supporting “healthy teeth” and reducing sensitivity.
Collagen Production: Eggshell membranes are rich in collagen, the protein that keeps skin firm and joints flexible. Studies indicate that eggshell extracts can “boost the body’s collagen levels,” helping counter natural age-related declines.
Safety Tips: Avoid swallowing large pieces to prevent throat injury and always boil shells to kill bacteria like Salmonella. Although trace heavy metals may exist, eggshells usually have lower levels than other natural calcium sources, making them safer if handled properly.
