Brief Summary:
The purpose of this study is to determine whether the amino acid taurine has effects on mood stability in bipolar disorder.

Condition or disease Intervention/treatment Phase
Bipolar Disorder Mania Bipolar Depression Drug: taurine Phase 2

Detailed Description:
Taurine is an amino acid that has some actions similar to mood stabilizers. Taurine is widely sold as a component of over-the-counter mood enhancing agents. However, controlled studies examining the mood effects of taurine are limited. An initial study in this laboratory looked at taurine's mood effects in individuals with bipolar disorder. This follow-up study is designed to further examine taurine's effects on manic symptoms. Subjects in the current follow-up study will add taurine or placebo to their current treatment regimen. Both depressive and manic symptoms will be tracked for three months to determine whether the addition of taurine affects mood symptoms.
