Hi there, I haven't personally tried Rhodiola although I plan to in the near future. One thing you have to remember is that no matter how many people tell you how good or bad a suppelent has made them feel, in the only way to know for sure if it will work for you is to try it. Twenty people might respond to your message saying that rhodiola is wonderful and then you might try it and it won't do anything for you. Or the opposite might happen where many people might say that it didn't work for them and for you, it will work wonders. Every one has a different biochemistry...for some, ginseng makes them nervous and edgy and for others it calms them down. You have to try it to know.
