Arctic Blue does not use plastic bottles for the liquid fish oil, only glass bottles. So we are sure that no hormone-disrupting substances can migrate from the plastic into the fish oil.

Pure Arctic MSC Fish Oil is produced according to GMP. Good Manufacturing Practice is the strictest quality assurance system for dietary supplements in existence. It mandatorily records how and under what conditions a product is made. Raw materials are checked and a preparation protocol is kept. This way, everything can always be traced afterwards, in case of a theoretical deviation.

Pure Arctic MSC Fish Oil shows no detectable cadmium in tests up to 50 ppb (parts per billion) and no detectable mercury in tests up to 10 ppb. This is as much as 10 times below the Norwegian medical standard and European Pharmacopoeia (handbook), which we as manufacturers must legally comply with.

Pure Arctic MSC Fish Oil is also regularly tested to 0.5 ppt with no dioxins or furans detected. Norwegian medical standard and European Pharmacopoeia limits for this are 2 ppt (parts per trillion). Of course, these analyses are done in reputable international laboratories using the same toxicity-equivalent testing methodology as established by the World Health Organization (WHO).

Pure Arctic MSC Fish Oil shows no detectable PCBs during tests down to 0.5 ppt. The Norwegian standard medical limit for PCBs is 3 ppt.

These figures are easier to understand when you know that a large fish like tuna is legally allowed to contain up to 1 mg of mercury per kilogram of fish.

1 mg/kg = 1000 ppb. Pure Arctic MSC Fish Oil contains no detectable mercury during tests down to 10 ppb and is therefore at least 100x purer than tuna in terms of this heavy metal.
