All supplements contain metals. This "warning" label is merely a ploy by the pharmaceutical
companies to steer people away from supplements. If any supplement contains trace amounts of lead it automatically gets this warning label. Which is ridiculous because every person, animal and plant has trace amounts of lead because of decades use of leaded gasoline and paints.
Additionally, a binder like Peactasol C may have trace amounts of lead but it cannot get into your body because it is bound up in the binder.
Econeugenics has 3 major studies, one done at Harvard University, that show this product dramatically reduces cancers, most notably prostate cancer.
