What weight loss supplements can people with Bipolar condition take?

I would like to know specifically what supplements to help aid weight loss for Bipolar people on weight gaining Bipolar medication (which slows the metabolism and increases appetitite)

I already know of Green Tea to speed up metabolism and suppress appetite and Acai Berry DOES help you look a bit thinner in the face and relieves minimal bloat if taken moderately.

What other supplements are safe?
