Hi im 17 and want to increase my height im 5,10 and should i take l arginine so yes how much per day and is it must to do workout after taking it?

Waste of money: You are most likely to reach your tallest potential height by following a healthy diet, getting appropriate sleep & and remaining physiclly active.Nothing you eat or drink will add inches.No exercise will make you taller.You can stunt your growth by the opposite, poor diet/sleep/inactivity can all take a toll.At 17 you are likely near the end of your growth phase.
