What is Shell?

A shell is the hard, protective outer covering of an egg, primarily made of calcium carbonate. It is formed naturally as the egg develops in the hen and serves as a barrier to protect the egg's contents from physical damage and bacterial contamination.

While not typically consumed, eggshells can be used in culinary applications for nutrient supplements, like a calcium supplement when ground into a fine powder. Health evidence generally focuses on food safety, with risks primarily associated with bacterial contamination from improper handling or consumption of raw egg shells.

For consumers, seeing 'shell' on a label typically refers to the intact, inedible portion of an egg, playing no direct nutritional role if not specifically processed for consumption.

Commonly found in: eggs, dietary supplements, garden soil amendment

What to watch

  • Improper handling of egg shells can lead to bacterial contamination such as Salmonella.

Benefits

  • Eggshells contain a high concentration of calcium, which can be beneficial when processed for dietary supplements.
FDA

The FDA regulates eggshells as part of food safety standards, ensuring they are clean and without cracks when sold.

Research

Research shows that eggshell powder can effectively increase calcium intake, but applications must ensure safety from contaminants.

Vegan

Eggshells are animal-derived, so they are not suitable for vegans who avoid all animal products.
