Tag: Boiling eggshells

Did you know that eggshells are primarily composed of calcium carbonate, making them a highly bioavailable and natural source of calcium for human consumption? Properly sterilizing these shells is a critical safety step to eliminate bacteria, particularly Salmonella, before turning them into a homemade calcium supplement.

Eggshells are approximately 95% calcium carbonate, making them a very potent and inexpensive source of calcium. This has led many to explore their use as a dietary supplement, but doing so requires careful preparation to eliminate health risks. Boiling is a key step in this process, ensuring the shells are sterilized before consumption.
