Height of an individual is determined by Genetics, Environmental & Nutritional factors and Hormonal
factors (e.g. growth hormone
An individual stops growing in height after the fusion of epiphyses (growth plates) of long bones which occur by the age of 19-21 yrs in male.
So...if you are below the above mentioned age group, then you have a good chance of achieving your dream height.
Make sure that you are taking a healthy & balanced diet, exercise regularly & avoid stress
Also avoid consuming any over the counter medication
that claim to increase height....it may be harmful.
Wishing you a good health.
Thanks & take care.
