A friend who takes the pill form, takes it regularly to keep in her system for consistent results.

I did not see much effect from taking the pill form and my doc recommended the tea, GABA Oolong instead. I have found it not only help my anxiety and some of my PTSD symptoms more effectively but the effects seemed to last longer as well. The problem can be dosing though, depending on whom you get the tea from and if they are reputable and consistent in their process. In that regard the pills can be better.

Either way with both, it is a water soluble molecule that metabolizes quickly and has to taken more frequently for consistent results, if anxiety is a constant problem.
