Bests & Worsts Reviews from Amazon

I had a Dr. tell me to start using this because I found out I have mold toxicity and some heavy metals. Zeolite is a natural substance so it does contain trace lead and aluminum as they all do, however I contacted the manufacturer to find out exactly how much this tests for. They didn't give me any kind of documentation or tests, but did say trace amounts. They said not to believe things on the internet and that zeolite doesn't allow the lead into the body. They said the amount of lead in it is within values that are aloud according to federal guidelines. The so called 3rd party tests they have posted on their site are not only outdated, but they weren't even used on humans and it was a very short study. How can they claim its pure or exactly how much lead and aluminum is in it if they don't do random tests and studies? I had a heavy metal test prior to using this. I had 0 amounts of lead in my system. Zero. I did have small amounts of aluminum. I also had some others such as thallium and barium. On my follow up test, not only did my levels not drop at all, my lead actually went up. No amount of lead in your body is good. It's actually very bad. So this product not only does not pull heavy metals from you, it can actually give you lead. I only drink filtered water and my shower has a filter on it. Don't trust anything this company tells you. I wrote to the company trying to get an explanation or any kind of information and they never wrote back. Funny how they'll write back when you have a question and they'll toss out bold claims, but if you have negative results they ignore you because they'll never admit to anything. If you do some research you'll see the FDA actually put out a big warning about zeolite products and lead. You think you're helping by taking something like this that makes big claims, but actually end up making things worse. I question how many of the reviews are actually real and how many who claim it works as actually had pre and post testing done. Anyone can claim they feel better when taking it, but the tests don't lie. If you decide to take any zeolite make sure you are getting pre and occasional post testing done.
