The choice of the best purification process for cod liver oil used in supplements depends on various factors, including the specific contaminants present in the raw oil, the desired quality and purity standards, and cost considerations.

The cod liver oil we use goes through a process of winterisation, deodorisation and filtration to ensure impurities are removed from the oil and remove odour and taste compounds. This ensures a high-quality cod liver oil that is safe from impurities and does not have an overly fish smell or aftertaste.
