is calcium water soluble or fat soluble in the body?
Confidence votes 41. Calcium is water soluble, but not fat soluble. It is the fifth most dissolved ion in seawater. On the other hand, fat is soluble into calcium in the body. The calcium will extract the fat from food in the digestive system, and they combine to form a foamy substance which is not absorbed by the body, and so the fat will be flushed out.
