What are people's opinions on bottled "lithium water" which is now sold on Amazon? Apparently there's a bunch of studies that show trace levels of lithium that naturally occur in spring water is neuroprotective and leads to fewer suicides. A friend of mine on Facebook asked if this is a good idea for someone who's depressed, I reflexively said no, because lithium is potentially toxic and shouldn't be taken in any form willy-nilly. However, a colleague of mine who's a paediatrician jumped in, and insists the data is very convincing, and that commercially available lithium water doesn't contain enough lithium to become toxic, unless you drank like a hundred bottles of it at once. However, my gut still doesn't feel like this is a great idea. Anyone care to convince me either way? Thanks.
