Which form of calcium supplementation is not acid dependent?

  1. Calcium carbonate

  2. Calcium citrate

  3. Calcium sulfate

  4. Calcium phosphate

The correct answer is: Calcium citrate

Calcium citrate is the only option that is not acid dependent, meaning it does not require the presence of acid in the stomach in order for it to be absorbed by the body. The other options, calcium carbonate, calcium sulfate, and calcium phosphate, all require some level of acid in the stomach for proper absorption. This is important to note because individuals with lower levels of stomach acid, such as older adults or those with certain health conditions, may have difficulty absorbing calcium from these forms. Calcium citrate is a more suitable option for these individuals as it can be absorbed easily in the stomach even with lower levels of acid.
