The best time to take zinc supplements for children varies from person to person, depending on their condition and whether they have a zinc deficiency. The best time of day for zinc supplementation is about one hour after dinner, which is conducive to its full absorption. Zinc promotes the growth and development of children, helps brain and intellectual development, improves immunity, and improves appetite. Zinc deficiency in children can cause low immunity, poor intellectual development, stunted growth and short stature, and even dwarfism. If children have short stature, yellowish hair, backward intellectual development, loss of appetite or frequent colds and mouth ulcers during their growth and development, they should take zinc supplements in time. If there are no signs of zinc deficiency, supplementation is generally not necessary. Zinc supplementation should be done about 1 hour after dinner, when the digestion of food is beneficial to zinc absorption and the utilization of zinc can be improved after sleep. Do not blindly take too much zinc as it may cause nausea and vomiting. You should eat a coarse and fine diet, eat more zinc-rich foods and avoid long-term consumption of refined foods. Try to avoid zinc supplementation and calcium supplementation at the same time, and go to the hospital regularly for body trace element checkups and timely supplementation.
