There are heavy metals in almost everything including Trace Minerals. There are heavy metals in the foods you eat and if it’s commercially grown, then there are more from pesticide residues. Arsenic, lead and other heavy metals are in pesticides, fungicides and herbicides. The question is, are naturally occurring heavy metals that are bound with plant proteins toxic? Evidence suggests they are not; however, we are not aware of any studies on this, so we can’t say with certainty.
