How do i grow taller with or without supplements? i am currently 5" and would like to increase my height to 5"5 :'?

I doubt it will ever be possible. At a listed age of 18, the growth centers in your bones are most likely closed and no increased height is possible. A single x-ray of your wrist/hand can be studied for growth centers. If open, adequate sleep, good nutrition and exercise support growth. If closed, you are done. There are no diet/supplements/exercises that increase height after growth centers close

Embrace yourself. At your age not much more growth can be expected.
