What should I do if my zinc levels are still low?

Given the persistence of low zinc levels, it is recommended to initiate zinc supplementation with zinc gluconate or zinc citrate at a dose of 15-20 mg per day. This should be taken orally, preferably with food to minimize gastrointestinal side effects, and continued for at least 3 months to allow for replenishment of zinc stores. It is also advisable to review the patient's current medications and supplements to identify any potential interactions that could be contributing to the zinc deficiency, such as high doses of copper or iron. If the patient is taking copper supplements, it may be necessary to adjust the dose or timing of these supplements to minimize interference with zinc absorption. In cases where zinc deficiency is severe or persistent, second-line interventions may include increasing the dose of zinc supplementation or adding other nutrients that support immune function, such as vitamin C. Regular monitoring of zinc levels and adjustment of the treatment regimen as needed are crucial to ensure effective management of the deficiency and prevention of associated morbidity.
