I saw this too.

I am just wondering about two things. the first, is dosage...the smallest dose you can get prescribed is 150 mg's of lithium carbonate - that's still a lot. there is lithium orotate (as a supplement), but do we really know how safe it is?
Secondly, doesn't lithium lower seizure threshhold?...and aren't those who've suffered multiple concussions or a TBI more at risk for seizures than the average person? (I thought I read this...).

Anyway, I too would like to know more.
