I'm sure it is good. Just use decernment with this Dr. He did a video, a couple years ago with a Dentist friend, stating how beneficial and harmless fluoride is.

I use this daily in my morning coffee. It has balanced my moods, given energy without anxiety, I sleep better, etc.. Now when you first try this, you have a burst of energy that can last for days, sleeping in "Cat naps" The benefit list goes on and on. I put this in the products I am developing. A small amount goes a long way!
