In Denmark, we have limit values for the content of three heavy metals in fish products. The MRLs concern cadmium, mercury and lead. If a product remains within the limit values, the heavy metal content does not pose a safety risk. We have chosen cod as the source of our product, as it is not a major predator, in which heavy metals typically accumulate. Alt Vild Nord collagen is analysed through third parties, so we always have a guarantee that the product does not exceed the limit values.
