The carbohydrates making up the algae cell walls are called alginate. Alginate has the unique and important ability of permanently binding heavy metals, radioactive substances and other toxins to its own molecules. The alginate cannot be broken down by the bile or saliva and cannot be absorbed by the body. It is eliminated from the body together with the heavy metals and radioactive substances.
Alginate binds to all heavy metals including Lead, Mercury, Cadmium, Cobalt, Radium and others. The binding process takes place whether the metals are radioactive or not. Alginate does not bind Aluminum which is considered a light metal but still toxic in excess amounts.
