I take it and makes me feel better. I heard of many other people that report an increase in energy and wellbeing.
Professor Boyd tested it and said it did not attach to the mercury in vitro. The product also has aluminium in it, but in a form that appears to be harmless. The FDA says it is a safe substance - whatever that means. I read some research about zeolites that show decreased toxin damage in rats that were fed zeolites. What I don't like about the company is that they claim NCD can chelate but fail to publish an study that clearly shows increased Hg excretion. I believe that many healthcare professionals recommend it because people feel better when they take it, not because they found that it is an effective chelator.

When I look at the facts i would say it can't chelate.
From my personal unscientific experience i would say it is possible that it helps with mercury excretion.
