At 25 years of age, all of the growth plates should have closed, so it is unlikely that one will grow more in height. None of the methods that have been tried, such as stretching, vitamins, and so on, have actually helped make people taller. You can certainly try simple things such as putting thicker insoles in your shoes, but as far as actually getting taller, it most likely won't happen.
