Yes. This is particularly important if you have ever had silver amalgam dental fillings or live near or downwind from an industrialized region or power plant.

Unfortunately there are no remaining pristine places left on our planet. Even the top of Mt. Everest is polluted with heavy metals and radioactive isotopes from above ground nuclear testing. Coal burning which releases high levels of mercury and other toxins is rapidly increasing as human demand for electricity escalates.
Alginate Can Remove Heavy Metals absorbed from previous Exposures. Alginate can also remove isotopes that have previously been absorbed by the human body from air, water, or food pollution. In the event that radioactive strontium is released into the body, the substance will be circulated by the blood until it is deposited into the bone structure. Even small amounts of radioactive pollution will expose surrounding cells with radioactive emission. Hence radioactivity should be removed from the body.
A percentage of strontium molecules stored in the bone structure is constantly released and is traveling with the bloodstream. As the blood feeds the saliva, gallbladder and bile, part of the released strontium ends up in the large intestine. Most of the liquid in the large intestine is reabsorbed by the body, including the radioactive isotopes, which are redeposited into the bone structure. Alginate can break this cycle, as strontium isotopes are bound to the alginate molecules and eliminated from the body.

The best prevention against heavy metal and radioactive absorption is to consume alginate before meals. This will ensure a heavy metal and radioactive absorption of almost 100 percent, as the alginate comes in contact with all molecules.
Heavy metals and radioactivity that have previously been absorbed by the body are leaching and approximately one percent finds its way to the digestive system, where heavy metal removal is a longer process. Alginate should be consumed over at least a 4-month period in order to remove heavy metals and radioactive absorption caused by previous exposure.
