Although LYSI's operations have been ongoing for several decades, the new processing plant, inaugurated in 2005 and expanded in 2012, elevated LYSI's status to one of the most advanced processors of its kind in the world.

The plant is uniquely equipped with highly specialised production units for complete fish oil processing.

The process includes neutralisation, bleaching, winterisation, distillation and deodorisation. The equipment has been specifically designed to minimise oxidation of the oil and to remove taste and smell in the final product by natural means.

Flexible production of specialty oils

As requests for new types of fish oils have increased, LYSI has escalated the import of crude fish oil from other parts of the world for processing in Iceland. The company has achieved optimal utilisation of equipment and know-how, and offers its customers an extended range of natural health products.


LYSI's main processing plants for fish oils are in Reykjavik. The company also runs a fish liver rendering plant, as well as a drying unit for fish heads, in Thorlakshofn.
