What is the testing for Rosita Ratfish Liver Oil?

Each and every batch of Rosita Extra Virgin Ratfish Liver Oil is third-party tested in a microbiological laboratory and certified to meet strict European regulations for potency and purity. View the results here

Isn’t ratfish a bottom-feeding fish that would absorb more contaminants (e.g. dioxins, lead, mercury, etc.) than most fish?

Ratfish are bottom feeders residing at depths of up to 2,000 meters. Crude ratfish liver oil (directly from the liver) does test above the European limits for contaminants, and it is not advisable to consume it, even for those in Norway who are able to obtain fresh ratfish livers.

Rosita uses an exclusive, patented heat-free and chemical-free natural method to purify the oil so it’s safe for consumption. This method makes use of a naturally occurring substance in the ocean that has the ability to attract and bind to contaminants like a magnet. This substance, together with its bound contaminants, can then be gently removed from the oil in a similar way that sediments are removed from a fine wine. 

Unlike most fish liver oil producers, who use molecular distillation (high heat) to remove/reduce contaminants, a process that destroys precious vitamins A and D, the Rosita process does not damage the vitamins. It keeps them intact just as they are in the fish’s liver. Once the ratfish oil has passed through the contaminant filter, its tests below the strict European guidelines.

It’s important to keep in mind that no fish you eat (nor, for that matter, any beef, chicken or pork) is completely free of dioxins and contaminants unless it is highly processed, which destroys the nutrients.
