If you’re referring to the viral claim “Boil eggshells and say goodbye to…”, it’s usually promoting eggshell water as a source of calcium. There is a kernel of truth—eggshells are mostly calcium carbonate—but boiling eggshells and drinking the water isn’t a proven treatment for a particular disease or condition.
What eggshells actually contain
Eggshells are predominantly calcium carbonate, so finely powdered, properly processed eggshell can provide calcium. However, casually boiling shells doesn’t reliably produce a measured dose of calcium, and improperly prepared shells can carry Salmonella or other contamination.
If you’re looking for more calcium
Safer, predictable sources include:
-
Milk and yogurt
-
Cheese
-
Calcium-fortified plant milks
-
Calcium-set tofu
-
Canned fish with edible bones
-
Some leafy green vegetables
For most adults, the goal is roughly 1,000–1,200 mg of calcium per day, depending on age and sex.
If you tell me what the viral claim says eggshells will help you “say goodbye to” (for example, joint pain, osteoporosis, or calcium deficiency), I can explain whether there’s evidence for that specific claim.
