I take both Cymbalta and Lexapro and have taken a variety of supplements with them (including
lean xtreme). I have never noticed any adverse reactions, except perhaps, norepinephrine induced hyper-vigilience when taking stims and such. Of course, I've been taking some form of anti-depressant for most of my life and I have developed an awareness to how I am responding to the supplements that I am taking.
With that being said, it's probably not the best idea to combine supplements with presciption medication as you do not know the possible drug interactions. However, if you have been psychologically stable for a long while you could always do an "experiment" and see how you respond. The most important thing here is making sure that you pay attention to your body and how the supps make you feel. If you get an adverse reaction; promptly discontinue usage. If you want to air on the cautious side (and I recommend that you do), you could start off with lower dosages than the product recommends. If you see no ill results, gradually increase the dosage to the recommended values.
The choice is ultimately yours. It is dependent upon whether you feel the risk of temporarily jeopardizing your well-being is worth the possible gains you could make by taking it. I know this might sound harsh but I feel that I needed to include it in order to give both sides of the argument. Good luck and keep us posted.
