Rated 4.5 out of 5 by 4 reviewers.
Rated 5 out of 5 by Great Product I have been ordering Swanson vitamins for many years; Suntheanine L-Theanine Stress Relax Tabs are a green tea extract that tastes great and takes the edge off when you take them on a continual basis. I Love them! July 6, 2013
Rated 3 out of 5 by Too Much Too much sugars and too high of a dose for me. Caused adverse reactions. October 8, 2012
Rated 5 out of 5 by Easy to use I can carry these chewable tablets in my purse to have with me at all times. Also I think the chewable form allows them to get into my sytem faster for quicker results. And I trust this brand. August 12, 2012
Rated 5 out of 5 by easy to take My son takes this for behavioral issues and it appears to help plus it is in a chewable format! His doctor was impressed that Swanson's carries a chewable version of this. It makes getting those morning meds down so much easier! July 23, 2009
