Innerzone: That said, one of my biggest skeptic points are testimonials from a site selling something. Surely they will only put good things on their site, right?

I just wanted to clarify, the testimonial was posted at a bipolar support forum. The poster didn't provide a link to the site that sells the supplements, they only mentioned it by name. I'm the one who ran that through a search engine, located the company's website and linked it in the post above.

It's always possible that the individual who provided the testimony was an agent of the supplement site but it's also possible that they are someone who genuinely suffered with bipolar disorder and found an effective means of managing it without the use of traditional medications. I frequently recommend the work of Jungian, John Weir Perry, to those who have experienced psychosis/a schizophrenic episode because I found it to be helpful but I'm certainly not getting any kickbacks from the publisher if someone buys his books or goes to see a Jungian analyst in their home town. It's also apparent to me that not everyone benefits from a Jungian approach.

At any rate, people can explore the links above and make their own decisions. Ideally, they should make those decisions in conjunction with their support teams (Professionals; Family and Friends; Peers, and; Mentors). Family, friends and peers in particular are often well-placed to provide valuable feedback in regard to daily functioning. In all cases, I would emphasize that the goal of any treatment is to improve or restore function -- if that's not happening, that particular treatment cannot be said to be effective for that individual even if it works well for someone else.
