At 17 years of age, many people are still growing, but the rate of height increase can be slow and depends mainly on genetics and hormones. In boys, growth may continue until around 18 to 21 years, while in girls it often slows earlier. It is important to focus on healthy habits rather than quick fixes, as there is no safe medicine or supplement that can suddenly increase height. Eating a balanced diet with enough protein from foods like eggs, milk, pulses and nuts helps bone growth. Calcium and vitamin D are also important, so include dairy products and get safe sunlight exposure. Regular physical activity, such as stretching, running, swimming or playing sports, can support good posture and overall growth. Getting at least 8 to 10 hours of sleep every night is very important because growth hormones are released during sleep. Avoid smoking, alcohol and junk food. If you feel your growth is very slow compared to others, it is best to consult a doctor to check for hormonal or medical issues.
