What is the percent elemental calcium in Calcium citrate?

The correct answer is: 21%

Calcium citrate contains approximately 21% elemental calcium. This percentage is important for healthcare professionals to calculate the appropriate dosing when recommending calcium supplementation for patients. It is crucial to remember the specific elemental calcium percentage in different calcium salts to ensure patients are receiving the intended amount of elemental calcium for their needs. Option A, which states 40% elemental calcium, is incorrect as that percentage is too high for calcium citrate. Option C, 30% elemental calcium, and Option D, 15% elemental calcium, are also incorrect as they do not represent the accurate percentage of elemental calcium in calcium citrate.
