In 2020 a cell culture lab-study performed by a group of Icelandic scientists led by Dr. Einar Stefánsson, Professor of Medicine at the University of Iceland, showed that free fatty acids found in fish liver oil can quickly destroy viruses, including SARS-CoV-2, the virus causing COVID-19. The study was conducted in collaboration with U.S. partners. Laboratory results showed fish liver oil with 1% and 2% free fatty agents destroyed 99.9% of SARS-CoV-2 within 10 minutes.
According to an article in Viðskiptablaðið in November 2020, the research, in collaboration with fish liver oil producer Lýsi hf. had been approved by the Scientific Ethics Committee and the first phase of the study was being planned with the participation of 30 infected individuals. Icelandic daily Fréttin recently contacted Professor Stefánsson for news of the project, but he said the research project had to be discontinued due to lack of funds.link
