Hello! I had gone through your query and understand your concern. Height of an individual is determined by genetics,nutritional factors and hormonal factors such as growth hormone. An individual stops growing in height after the fusion of the epiphyses of the long bones, which occurs by the age of 16-18 years in females. Considering the fact that you are 23 years old your bones had already fused and neither food supplements or specific exercises can have an obvious effect in increasing your height. So be careful with supplements and drugs proclaimed to increase the height after 18 years old because this is impossible. Hope it answered your query. Take care Dr.Rovena Murati
