ORIGINAL BROWN SEAWEED EXTRACT Modifilan is a dietary supplement made from the richest variety of natural, wild-grown, brown seaweed. It was developed following the Chernobyl disaster to provide an organic and natural way to assist with the elimination of unwanted heavy metals, especially mercury and lead. May be of assistance to those undergoing or exposed to radiation. To make Modifilan, raw seaweed Laminaria is hand-harvested in the wild natural habitat where it grows to a size large enough to extract the inner part of the leaves. Modifilan is referred to as an extract, but basically it is the dried, concentrated juice of brown seaweed. It is a simple and absolutely natural product, a true whole food substance that is not formulated.
