Happy Water, your thoughts?

So I recently came across a new product on the shelves of our convenient stores here in Canada called Happy Water, https://livehappywater.ca.

Being curious I decided to look into it thinking it would be some cool new healthy water product. However, after looking into it, I noticed that it has one of the highest Floride, https://en.m.wikipedia.org/wiki/Fluoride, contents of any commercial water at 1.4ppm. Also noticed that the happy part come from the lithium, https://en.m.wikipedia.org/wiki/Lithium, they add to the water. Lithium is used to treat depression and is toxic in fairly low dosage. Another strange thing is they claim neurogenesis, https://en.m.wikipedia.org/wiki/Adult_neurogenesis, in the name which is the creation of new neurons in the brain.

What are your thoughts on this product?
