Calcium and zinc can be supplemented at the same time, e.g. by taking calcium and zinc supplements, but if they are taken as single supplements, it is recommended that they be taken separately. Calcium and zinc are both metal ions, and when both are supplemented in the form of a single dose, such as calcium gluconate and zinc gluconate, it is recommended that there be an empty space of about two hours between the two, so as not to interfere with absorption by having them compete for the same carriers. If you are taking calcium and zinc gluconate supplements, you can take them at the same time. It is also important to pay attention to a balanced intake of various foods in daily life. For example, foods such as lean pork and lean beef are rich in zinc, while foods such as milk and sesame paste are rich in calcium. When choosing calcium and zinc medication, you should consult a relevant professional doctor and follow the doctor’s instructions.
