Should I be concerned about the iodine content in fucoidan?

We are the first and only to provide both an Official Independent Radiation Test Report and an Official Seaweed Origin Declaration upon request with every order. These reports make it clear that we do not use any seaweed of Pacific origin in the making of our fucoidan products, and that they have no detectable levels of Cesium-137, Cesium-134, or Iodine-131 radiation contamination. 

The recommended daily value for iodine is 150 mcg, though the U.S. National Academy of Sciences lists the maximum tolerable level of iodine intake as 1.1 mg (1100 mcg) of iodine per day. Iodine is necessary for the human body to function properly. Fucoidan Force and Fucoidan Phoenix provide a small dose of iodine on a daily basis.

How safe is fucoidan?

Fucoidan may be taken indefinitely to help promote good health, cell-to-cell communication, and tissue maintenance, with no side effects. Clinical testing confirms that high purity, certified organic fucoidan extracts are safe for human consumption. 

To be sure you are getting the full benefits of fucoidan there are several things you need to know:

Strength – The percentage & amount of fucoidan found in the brown seaweed extract in each bottle.
Species – Type of seaweed used Mozuku, etc.
Origin – Ocean from which the seaweed is harvested.
Extraction Method – Hot or cold, water or solvents.
Support Ingredients – Types, amounts & purity.
Independent Third-Party Testing – This is critical because without it you cannot be certain about the actual amount of fucoidan you’re getting, or if the fucoidan is contaminated with radiation.
