The world’s only patent for heat-free and chemical-free filtering

Rosita is the only company to hold a patent for a truly gentle chemical-free and heat-free method to purify your cod liver oil, developed with support from the University of Stockholm. 

This extremely unique method uses a natural substance from the ocean that binds to contaminants in the oil, followed by filtering — like decanting a fine wine. It is highly effective at reducing contaminants but does not alter or damage the oil’s nutrients in any way. (Here’s more information about the nutrients inside your Rosita Extra Virgin Cod Liver Oil.)

No other company has this patent, which means that every other cod liver oil
producer has to use heat to cleanse their oils.
