History of Lysi: Tryggvi Olafsson

Operating since 1938

LYSI's story began in 1938 with two ambitious brothers, Tryggvi and Thordur Olafsson, who had a vision to create Iceland's largest cod liver oil producer – a title the company still holds today.

In the beginning, LYSI only exported products in bulk, then in the 1950‘s the company started producing cod liver oil in consumer packaging. Since 2005 LYSI has produced its fish oils in a brand new and uniquely equipped processing plant in Reykjavik with 13,000 tons capacity.

Today LYSI is known all over the world for its expertise on fish oils, high quality products and outstanding services, skills which have been accumulated for over 85 years.
