Eggshell Powder Calcium Benefits: Eggs are considered very beneficial for our health, which is why people eat them in large quantities and then discard the shells. However, eggshells are considered the cheapest and most effective natural source of calcium. While most people throw them in the trash, when used correctly, they can prove to be very beneficial for bone health. Ready-made eggshell powder is available in the market, but it can also be prepared at home. Let us tell you about it.
What is an egg shell after all?
The eggshell is the hard outer layer of the egg, composed mostly of calcium carbonate. It also contains small amounts of protein and other minerals. Calcium is the mineral considered most essential for strong bones and teeth. Research suggests that a chicken eggshell is composed of approximately 40% calcium, meaning just one gram of eggshell provides a significant amount of calcium.
How effective is it as a calcium supplement?
According to research published in PubMed-indexed studies, the calcium carbonate in eggshells is the same form used in most calcium supplements. Studies have found that eggshell powder is absorbed as well by the body as standard calcium supplements. Some research even suggests that calcium from eggshells may be more beneficial to the body than pure calcium carbonate supplements, likely due to certain natural proteins and compounds present in the shells. In addition to calcium, eggshells also contain minerals such as magnesium, phosphorus, strontium, and selenium, which play a role in supporting bone strength.
It can also reduce the risk of osteoporosis
According to healthline, it may reduce the risk of osteoporosis. Osteoporosis is a disease in which bones weaken and the risk of fractures increases. Aging is one of the biggest causes, but long-term calcium deficiency can also contribute to it. Some studies have found that taking eggshell calcium, along with vitamin D and magnesium, improved bone mineral density in postmenopausal women. In some cases, it was even more effective than standard calcium supplements.
Is caution necessary?
Eggshells are considered safe when prepared properly. However, swallowing large pieces can be dangerous, so they should always be ground into a fine powder. Furthermore, eggshells can harbor bacteria, such as salmonella. Therefore, it's important to boil the eggs thoroughly before using them.
