Bests & Worsts Reviews from Amazon

I did a hair analysis and it showed I had high levels of lead, arsenic, and nickel. I couldn't figure out where I was getting lead from. I tested all the water I was drinking and various herbs, but could not find any lead. Then I tested ConcenTrace trace mineral drops and found it had high levels of lead in it. I am very disappointed that this is even allowed to be sold in the US. I tested it 3 times. It has been giving me brain fog and I am throwing it out and will never use it again. I recommend you do the same.
