Calcium absorption
Some research suggests that calcium from eggshells can be absorbed effectively and may be comparable to calcium from purified calcium carbonate supplements.
However, “natural” does not automatically mean “better.” Commercial calcium supplements have advantages such as standardized dosing, quality control, and clearly stated amounts of active ingredients.
Joint comfort
Eggshell membrane, not the hard eggshell itself, has been investigated in clinical trials involving people with joint discomfort and osteoarthritis.
Some studies have reported improvements in joint pain, stiffness, or mobility with standardized eggshell-membrane supplements.
