You asked if there was any reliable studies done on Heavy Metal detox.
My wife and I can across a site, and came across the following information about a clinically proven detox for heavy metals which is 100% natural. It is the result of 3-year long clinical trials with 350 people that cost over $1 million. The products name is called HMD for Heavey metal detox and has a patent pending.
My wife and I live in Southern Spain and we both took the product and both have felt more energetic and after we saw all the testimonials on the website, and having taking it ourselfs, we highly recommend it. I believe there are several websites that offer this HMD product but one which you can try is detox-heavymetal.com Well best of luck and God bless Tom
