My naturopath has recommended MetalloClear to clear heavy metals. The description of the product is:

# Up-regulates the genetic expression of metallothionein, an important protein that binds to metals in cells and facilitates their elimination.
# Supports the metabolism of specific heavy metals, but does not facilitate the excretion of certain healthful minerals such as calcium, magnesium, selenium, and zinc.
# Has no reported serious adverse effects, unlike some other approaches.

It seems to be a safe because no serious side effect is reported.
Has anyone tried this product? What was your experience?
