Do the pills sold over the Internet really work and how much would they make a 16-year-old girl grow who is 5' and desperate to grow taller?
First, let's look at reasonable expectations. You can use your
mother's height as a gauge of your eventual full height. At 16, you
still have about 3 years to attain full stature. There are no pills
available by prescription or OTC that can accelerate of increase
your growth rate. While a balanced diet will help prevent any
deficiency states, further alteration of diet (as more protein)
will not affect your growth.
