Risk of Heavy Metals in Biosea

Seaweeds are really good at sucking up chemicals in the water. Where we grow seaweed we test the water and the seaweed and we do not have detectable levels of lead, cadmium or mercury. We do not ship any product that has more than detectable levels. Why eat to be healthy but then ingest levels of toxic chemicals.

But in some areas and for some species they do concentrate and are used in water remediation. There is seaweed grown in the mouth of the Rhine River to extract out nitrogen, lead, cadmium to reduce the levels going into the North Sea.

Other seaweed is not harvested but washes up on the shore after storms.  In contrast our seaweed is grown in the clean sea (monitored), harvested, dried and put into product.

All with the latest state of the art gate to plate tracking process and formally organically certified.

So be careful of seaweed products is grown in river mouths, or is not carefully monitored.

NB.  Back in 2012,researchers found seaweed (K. alvarezii extract) exhibits potent anti-genotoxicity effects in a fish model; and thus seaweed extracts may be recommended as a supplement in fish meal and may benefit humans ingesting Hg-contaminated fish.
