What is the most approved way to correct a zinc deficiency and with which compound?

The most approved way to correct a zinc deficiency is through supplementation with zinc gluconate or zinc sulfate. For mild deficiencies, a dose of 10-20 mg of zinc per day is often recommended, while more severe deficiencies may require higher doses up to 30-50 mg per day. The duration of supplementation depends on the severity of the deficiency and the individual's response to treatment but typically ranges from a few weeks to several months. In cases where oral supplementation is not tolerated or effective, intravenous zinc may be considered. Second-line interventions may include dietary changes to increase zinc intake from food sources, such as oysters, beef, chicken, and fortified cereals. It's essential to consult with a healthcare provider to determine the best course of treatment, as excessive zinc intake can cause adverse effects. Additionally, addressing the underlying cause of the deficiency, such as malabsorption or increased loss, is crucial for effective management.
