Here's another interesting article about using lithium orotate to treat bipolar. It discusses an old controversy from a study in 1979 that it sounds like is used to say how dangerous lithium orotate is. There are links to a bunch of other article on lithium orotate at the bottom of the page along with a lot of comments.

This is the brand I use. I buy it on Amazon, and noticed that's down to $15.50 for a bottle of 200.
