I was hesitant but curious about this water. It is literally black. The contents are nothing more than purified water and fulvic trace minerals that are naturally found in the earth. It provides electrolytes and has zero calories. And....it tastes like water. Would I buy it again? Probably not. I bought it out of curiosity. If I want trace minerals, I'll take a proper supplement dosage of them. Otherwise, I like to know that the water I'm drinking is clean.
