My 4-year-old son once drank Fuwa calcium zinc gluconate oral liquid for 3 months. Later, the doctor said that it was unnecessary and decided to adjust his diet and stop drinking. Can Fuwa drink for a long time? I don't know how long you mean by long term. Personally, I think it depends on the specific situation. If the child is short of calcium and zinc, he should drink it. There is no need if there is no shortage. Just drink enough milk and eat enough meat every day. What about Fuwa's brand? I think it's good. Fuwa's sour and sweet orange flavor is also liked by children, and it has no side effects and is quite safe.
