Hi, Cindy.

This is natural (mineral) lithium. Not the man-made, chemical stuff.

Lithium actually used to occur in all sorts of things naturally, including mineral water. It was very easy to obtain also as "salts." Then in the 60's (or so), the FDA decided it was "dangerous." The so-called coincidental thing was at the same time, mental professionals were just realizing its benefits to calming the mind, and ta-da, now we have pharmaceutical companies making it and you can only get it through a prescription.

What you get in the prescription is many, many times more potent than the mineral itself.

I just got mine yesterday, both my husband and I are trying for SAD. Will let you know if anything good or bad comes from it.
