The pubertal growth spurt usually goes on till 18 years,and sometimes till 21 years.
All you can do is take a good healthy balanced diet and ensure good physical activity.
If you or your parents think your height is grossly less than normal,consult your paediatrician or an endocrinologist.
No medicine or supplement can increase the height beyond what is genetically programmed!
