Taking calcium tablets does not affect height growth, and some adolescents who do not have adequate calcium intake in their bodies can also take calcium tablets to promote height growth. Human height growth is influenced by many factors, and calcium intake is only one of the many influencing factors. Parents’ hereditary genes, intake of multivitamins, minerals and proteins, sufficient sleep, proper sunlight exposure, reasonable exercise, actual age of body bones, mental state and emotional influence, as well as the influence of life, work and social environment, etc., all have a greater impact on height. Healthy adolescents who have a basically normal diet and exercise generally do not need calcium supplementation. Calcium supplements may only be needed if symptoms are associated, such as cramps in the limbs, physical weakness, insomnia and irritability, lack of concentration, and excessive sweating.
