Taking zinc supplements can promote growth, but they have limited effect. Zinc is an essential trace element. For patients who are in their growth period, zinc supplementation can promote height growth. This is because zinc is involved in the synthesis of growth hormone. Growth hormone is an important hormone that promotes the growth of the human body. A deficiency of this hormone can lead to dwarfism. However, patients should not overly fetishize this effect. In most cases, the patient’s height is closely related to his or her genetic factors. Although the patient’s height can be promoted to a certain extent through some acquired efforts, such as strengthening nutrition, physical exercise and supplementing with appropriate trace elements, the specific promotion effect is not particularly significant. Therefore, zinc supplementation can only promote the synthesis of growth hormone, and then indirectly promote the growth of height, and this aspect of the factor is not a determining factor. In addition, patients must be aware that if excessive zinc supplementation, it will also cause some harm. For example, patients may experience zinc toxicity, which can lead to slow growth, anemia, and so on. Therefore, it is recommended that patients who want to grow taller can take zinc supplements in moderation under the guidance of a doctor.
