Problem analysis: Hello, as you said, zinc gluconate can promote growth and improve taste. When zinc is deficient, there will be poor taste, poor sense of smell, anorexia, and lower growth and intellectual development than normal people. Because it is a weak acid and weak base salt, the absorption and utilization rate of zinc is about 14%. After taking it, it can still combine with gastric acid in the body to produce zinc chloride, so it has certain side effects, mainly gastrointestinal reactions, such as nausea, vomiting, loss of appetite and so on.

Suggestion: It is recommended to take it after meals to reduce the irritation to the gastrointestinal tract. High zinc content may antagonize the absorption of other trace elements such as calcium and iron. Long-term use will lead to calcium deficiency, anemia and other symptoms. After taking it for a period of time, it is necessary to test whether there is still zinc deficiency in the body. If there is no shortage, you should stop taking medicine.
