Calcium inserts fit into the mineral port of certain ionizers and are useful for increasing pH where water is soft, lacking minerals or has a low pH. Calcium Inserts also may be useful in cases of severe calcium deficiency. This product does not give a substantial amount of dietary calcium, but the calcium that goes through a water ionizer does get ionized and becomes more bio-available. These inserts are usually not needed as typically there is plenty of calcium in most US water supplies.
These calcium inserts are only for Jupiter Water Ionizers with mineral ports.
