Adaml,
Actually lithium is really a metal in a host rock like gold, silver, then it is processed. I think I read that it is then combined or something like that to a sodium so that it can be safely absorbed by the body helping to "dilute" it so you will not get toxic levels of the metal which is the same reason you need to maintain a balance of sodium in your body by not taking diuretics, and be sure to drink plenty of fluids to keep the kidneys functioning properly. Oh I am sorry, I am rambling.
Any way I am happy to hear "lithos" has been good for you, I hope over time I will be happy that I made this choice, cause depakote sucked.

Stay in touch

CamW , am I right about this? Perhaps you could explain this correctly?
