Hydroxyapatite (MCHC) and Iron can interact. In single-meal studies 300-600 mg calcium reduced iron absorption by 50-60%. Long-term studies of raised calcium intake show no change in iron status, so the effect matters most for people treating iron deficiency. Separate by 2+ hours. Take iron away from hydroxyapatite and other calcium products, ideally with vitamin C.
