Dear doctor, I am 16 now, how can I increase my height growth?

Naturally raise HGH. Most men stop growing around age 18- but occasionally some will grow until age 21 or so. Most 16 year olds won't grow more than another inch or so but some have a late growth spurt. Have a healthy diet and take a good multivitamin- low zinc can limit growth. Try going to sleep by 10 pm. Taking measures to increase your production of growth hormone can also help. See http://bit.Ly/1cyctlq.
