While it’s true that eggshells are mostly calcium carbonate (the same form found in many supplements), there are serious concerns:
🚫 Risk of contamination: Eggshells can carry Salmonella bacteria—even after boiling. Home preparation doesn’t guarantee sterilization.
🦷 Poor absorption: The body absorbs calcium from food (like dairy, leafy greens, fortified plant milks) far more effectively than from powdered shells.
⚠️ Physical irritation: Coarse or improperly ground shell particles can scratch the throat or digestive tract.
đź’Š No quality control: Unlike regulated supplements, homemade eggshell powder has unpredictable dosage and purity.
Major health organizations—including the NIH, Mayo Clinic, and Academy of Nutrition and Dietetics—do not recommend consuming eggshells as a calcium source.

If you’re looking for natural ways to boost calcium and overall wellness, try these evidence-backed alternatives:
Dairy or fortified plant milks – 1 cup = 300–450 mg calcium
Canned sardines or salmon (with bones) – Rich in calcium + vitamin D + omega-3s
Collard greens, kale, bok choy – Highly absorbable plant-based calcium
Almonds and tahini – Good sources of calcium and healthy fats
Weight-bearing exercise – Walking, lifting weights—critical for bone density
💡 Fun fact: Vitamin D (from sunlight or food) helps your body absorb calcium—so pair them!
