As the oceans become increasingly polluted, this also affects the fish in the world’s oceans. The further down the food chain the fish are, the higher the levels of PCBs and heavy metals. For example, sardines have lower levels than cod.
The NORSAN fish oil, which we use for our Omega-3 Total, is carefully purified from PCBs and heavy metals in Norway. Thus, the oil also shows best values in this respect: Less than one fifth of the EU maximum limit and comparatively only 2% of the amounts contained in a serving (100g) of cod. If one tablespoon of total omega-3 oil is consumed daily, this represents only about 10% of the average daily intake of PCBs from other foods.
