Unlikely to happen: The growth centers of your bones determine how tall you can grow.Most growth centers will close at 16-19 years of age in males. After that happens, you can not grow taller. At 21 you are done growing. If your growth centers were open, a balanced diet/rest ; healthy physical activity would support good growth.There are no special diets, meds or exercises that make you taller.
