I am 18yrs and i'm not satisfied with my height.please suggest some advice to gain height.i'm dying to grow taller and patient enough for the result.

Growth very unlikely: An 18 yr old is not growing taller if her growth plates have fused. If not fused, she will grow a little bit (pediatrician's growth chart for her can tell if growth has stopped). To look taller, one can choose properly designed clothing & shoes, and have good posture. Vitamins, supplements, "special" foods, exercise, etc... will not make a person living in the U.S. taller (height here is genetic).
