Icelandic cod liver oil – or lýsi – came out last in a Danish research project on the freshness of various fish liver oils purported to be high in Omega-3.
One of Iceland’s most famed products is lýsi, a cod liver oil that has been drunk or taken in pill form for decades now, and is touted as having many health benefits. While the benefits of Omega-3 fatty acids are numerous, Icelandic cod liver oil does not appear to hold up well to the freshness test.
DV reports that the Danish radio show Kontant conducted a research project of various fish liver oils available on the market. In terms of freshness, they measured the different oils for their TOTOX levels, to test their rancidity.
In the final results, lýsi came out as having the highest TOTOX level of any other fish liver oil on the market.
Jón Ögmundsson, the quality manager of the company Lýsi, told Icelandic state broadcasting that the matter was pure speculation. Furthermore, he added, lýsi has been measured with even higher TOTOX levels than the Kontant research found without it doing harm to anyone.
