Source Naturals Brand L-Theanine may have a slight edge in terms of effectiveness when compared to other brands of L-Theanine. Most likely I'll try this brand again.

This supplement has proved itself. I no longer have to take blood pressure tablets. I have been on this supplement for many months and continue to have great blood pressure readings.
