One of the best things I have spent my money on was something to help the oxygen in my body. In all honesty I am not sure I understand it all. As close as I can get the solution binds with free radicals in my body to make oxygen. That $35.00 was the best money.
I have never gotten to the number of drops recommended on the bottle. What I can say is I can feel it when I skip putting a couple drops in a bottle of water.
I got it at my local vitamin and supplement store.
