Dogodlvr,
i am relieved to know you do have doc's indications with regard to dosages. do be cautious however, especially at first, and buy a good brand...
I am not sure if this has now changed, but last i knew the FDA did not require/enforce standardization of content for supplements which means each pill and certainly each "lot" could contain slightly varying amounts of lithium orotate to what is declared on the label.
