Claim: “Boiled eggshell water cures disease”
Reality: There is no scientific evidence that eggshell water treats or prevents any disease. While calcium is essential for bone health, drinking boiled shell water delivers an unmeasured, inconsistent dose—and cannot replace medical treatment.
⚠️ Claim: “Eggshell powder strengthens bones”
Reality: Eggshells are a source of calcium carbonate. Some small studies suggest calcium from eggshells may support bone density when properly processed and dosed—but:
- The calcium must be finely ground to be absorbable
- Bioavailability depends on stomach acid and vitamin D status
- Unprocessed shells pose risks (see below)
📊 Research note: A 2003 study in the International Journal of Clinical Pharmacology Research found that eggshell calcium plus vitamin D improved bone markers in postmenopausal women—but this used pharmaceutical-grade, sterilized powder, not homemade preparations.
