Zinc is one of the indispensable mineral elements in the human body, which is important for human growth and development, and maintenance of normal functioning of the body. When zinc is deficient, slow growth or even dwarfism, taste disorders, gastrointestinal disorders and other conditions may occur. 1. Zinc supplements: When zinc deficiency is serious, you can prioritize taking zinc supplements such as lysine glucosamine zinc granules, zinc gluconate oral solution, licorice zinc granules, etc. under the guidance of your doctor, so as to rapidly improve the state of zinc deficiency. 2. Food: When zinc deficiency is not serious, it is best to use dietary supplements, consume more shellfish, red meat, animal offal and other zinc-rich foods. It is important to note that zinc supplementation should be done in moderation, as too much supplementation may cause nausea, vomiting and other adverse reactions.
