Calcium supplements come in two main types calcium carbonate and calcium citrate Calcium carbonate tends to be more affordable and more commonly produced but has to be taken with food for the body to absorb it Calcium citrate can be taken with or without food but is more frequently given to people with gastrointestinal issues
Calcium carbonate is more commonly available It must be taken with food because it needs stomach acids for the body to absorb it It contains 40% elemental calcium the highest amount in supplement form for maximum absorption Most of the time it is taken more than once daily It is usually affordable and found in some over the counter
Space filling model of part of the crystal structure of calcium carbonate CaCO₃ [Wikimedia] CaCO₃ is a widespread compound found in chalk lime marble and more This substance is a crucial pillar of human life it is used in construction to manufacture paper and plastic and in many other spheres
6 Le carbonate de calcium est très faiblement soluble dans l eau pure de l ordre de 15 20 mg L −1 25 °C mais soluble dans l eau charge de dioxyde de la solubilit des gaz dans l eau augmente avec la pression donc avec la hauteur de la colonne d eau et contrairement celle de la plupart des solides diminue lorsque la temprature augmente
Calcium carbonate is cheapest and therefore often a good first choice Other forms of calcium in supplements include gluconate and lactate In addition some calcium supplements are combined with vitamins and other minerals For instance some calcium supplements may also contain vitamin D or magnesium Check the ingredient list to see which
