Studies show that while eggshells are a rich source of calcium, they may carry bacteria like *Salmonella enteritidis*, posing a food poisoning risk if not properly prepared. Therefore, understanding the significant risks of eating eggshells, even for their nutritional value, is critical.

Eggshells are approximately 40% calcium by weight, making them a readily available and inexpensive source for this essential mineral. To safely prepare them for consumption, proper sanitization and drying are crucial steps, with baking being the most effective method for both purposes.

Eggshells, long discarded as waste, are primarily composed of calcium carbonate, the same mineral that builds bones and teeth. In fact, approximately one eggshell can provide a full day's calcium requirement for an adult. Beyond being an eco-friendly source of nutrients, research suggests they may offer unique health advantages over standard supplements.

An eggshell is composed of up to 98% calcium carbonate, but its surface can harbor harmful bacteria like Salmonella. While it offers a low-cost, effective source of calcium, proper safety measures are essential to make eggshell powder safe to consume and avoid health risks.

Consisting of approximately 95% calcium carbonate, an eggshell is a potent and inexpensive source of calcium. Finding the best way to extract calcium from eggshells depends on its intended use, whether for a human supplement or a plant fertilizer.

According to research, just half of an eggshell can provide enough calcium to meet the daily requirements for many adults. This makes properly prepared ground egg shells a surprisingly potent and economical source of this essential mineral for humans, provided safety precautions are meticulously followed.

According to a 2022 study in the *Czech Journal of Food Sciences*, eggshell powder contains a crude protein content of approximately 2.11% to 3.92%. While this is not a significant amount, the overall nutritional profile varies depending on whether the shell's membrane is included.

Eggshells are primarily composed of calcium carbonate, a common form of calcium found in supplements. Each gram of a chicken eggshell contains a significant amount of calcium, making it a potentially rich, natural source of this vital mineral. While using crushed and sterilized eggshells as a dietary supplement has been discussed, understanding how much calcium they contain and other factors is crucial.

Chicken eggshells are roughly 40% calcium by mass, with each gram providing around 381–401 mg of this essential mineral. This makes eggshell powder a surprisingly potent and bioavailable alternative for boosting your calcium intake, provided it is prepared correctly.

Studies suggest eggshell powder's calcium may be more bioavailable and effective for bone density than purified calcium carbonate, especially for postmenopausal women. However, it comes with important preparation and safety considerations not present with commercial supplements.
