What Makes Our Fish Oil So Special?

At Rosita Real Foods we are dedicated to providing quality handcrafted products that have been produced in harmony with nature. Our oils are a sustainable and natural source of pure fatty nutrients that boost your health and consciousness.

Rosita Extra-Virgin Ratfish Liver Oil (RFLO) contains a rare source of “Alkylglycerols”, a naturally occuring ether-lipid. Alkylglycerols have remarkable anti-inflammatory properties and help to stimulate the immune system.

An exclusive cold-process artisan method extracts the oil and preserves the delicate nutrients that are naturally present in wild ratfish livers. The resultant oil is as pure and authentic as it was for our Nordic ancestors hundreds of years ago.

Rosita Real Foods provides pure, natural and premium Extra-Virgin oils. We do not use any heat, pressure or metal containers or treatment in the Rosita Method, and this is very important. These oils are very delicate and must not be heated, extracted through pressure or exposed to air or metal in the process. The fish and extraction process receive special treatment, with each liver inspected and only the best chosen and placed in a dark, oxygen-free environment. Great care is taken to monitor this process to ensure the oils retain their freshness and purity.

Rosita Premium Extra-Virgin Ratfish Liver oil has been revered above all other fish oils by Norwegian Vikings and Scandinavian fishermen for centuries. This very rare and uniquely handcrafted oil contains a wide spectrum of naturally occurring fatty acids, fat soluble nutrients and antioxidants.

Product Highlights

Frequently Asked Questions

WHAT DOES RFLO TASTE LIKE? Our Ratfish Liver Oil has a mild, rather buttery taste. In comparison to our EVCLO, it has been described as having a less ‘fishy’ taste to it. RFLO does absorb rapidly, so any taste should disappear quite quickly. RFLO is best taken with food, which can help minimise the taste of the RFLO. Additionally, after taking RFLO, you can drink some water or another drink of your choice to help wash down any taste. Always remember to gently shake the bottle before you use it. As Rosita’s RFLO is a full-spectrum fish liver oil, it is comprised of various fatty acids. These acids may congeal and separate when the oil has been refrigerated. All the stearin, waxes and triglycerides may look separated, either partly or fully. Please note that this is perfectly natural for fresh, wild and raw fish liver oil. You may take the oils out of the fridge 3-5 minutes before use to allow them to evenly mix and to permit the efficient use of the dropper. This is particularly important for the 10ml dropper.
HOW IS THE OIL EXTRACTED FROM THE RATFISH LIVER? We prefer to keep our fish oils as natural and pure as possible. We hold ourselves to a high standard to ensure that our customers get premium extra-virgin oils. So, we do not use any heat, pressure or metal containers or treatment when collecting and processing our oils. This helps to keep the delicate oils pure. Once the livers have been carefully removed from the fish, each liver is inspected for quality. The best livers are then stored within a dark, oxygen-free environment. Within temperatures slightly higher than the ocean, the livers naturally release the oil. We meticulously regulate this step to ensure that the oil is pure and retains its nutrients. Any contaminants are removed using a patented method with the help of natural materials. Once again, no chemicals or heat are used in this removal process. Finally, the oil is stored within a cold, dark environment without oxygen. This keeps the oil fresh and it can be tested for purity prior to being bottled.
IS ROSITA RFLO SAFE TO USE? Not only are our fish oils pure and natural, we also get them independently tested by third-party laboratories. This helps to ensure that our oils are free from contaminants such as mercury, lead, cadmium, dioxins and PCBs. Our fish oils are therefore safe to use.
CAN I TAKE RFLO WHILE BREASTFEEDING? RFLO is safe to take while breastfeeding. Breastfeeding mums may consume RFLO directly (2 - 5 drops daily with food) and allow the rich nutrients to pass through the milk to baby. However, you should always check with a healthcare practitioner first. Infants older than 3 months can have 1 - 2 drops of RFLO daily or as needed mixed with breastmilk, baby formula, or food. Again, it’s important to check with a healthcare practitioner first.
WHAT ARE THE INGREDIENTS OF RFLO? Wild, handcrafted extra-virgin Ratfish (Chimaera Monstrosa) liver oil. Less than 0.3% acidity. No synthetic vitamins are added to our oils. Ratfish liver oil has naturally occurring vitamins, omega fatty acids and alkylglycerols. It contains vitamins A, D and E, as well as omega-3, -4, -6, -7, -9 and -11 fatty acids. RFLO also contains natural antioxidants that can help to protect your body against free radicals on a cellular level.
DOES RFLO CONTAIN MERCURY OR ANY OTHER CONTAMINANTS? Independent testing completed by a third-party has shown that Rosita Real Foods fish oils do not contain mercury and other contaminants such as lead, cadmium, dioxins and PCBs.
IS ROSITA RFLO FROM A SUSTAINABLE SOURCE? Rosita Real Foods’ fishermen utilise authentic, traditional methods to catch the ratfish. Small fishing boats are used so that less damage is done to the environment than larger, commercial fishing vessels. The fish are caught using the long-line fishing technique, which is beneficial as it limits bycatch, and is sea-bird friendly, minimising the impact on our ecosystem. Additionally, long-line fishing allows us to release any juvenile fish that are caught. Along with our sustainable techniques, we adhere to fishing quotas set by the Norwegian government. These quotas help to ensure that overfishing does not occur, and the survival of the fish is safeguarded. Read our blog about sustainable fishing practices for a deeper delve into our practices.
WHAT ARE THE BENEFITS OF RFLO? Studies have suggested that RFLO has anti-inflammatory properties and can support the immune system. The oil is naturally rich with alkylglycerols with a concentration of up to 33%. Alkylglycerols are fatty nutrients that are antioxidants and known for supporting the immune system. RFLO also contains essential fatty acids, vitamins and natural antioxidants. It contains omega-3, -4, -6, -7, -9 and -11 fatty acids, and vitamin A, D and E. The natural antioxidants, such as squalene, can help to protect your body against free radicals on a cellular level. In comparison with synthetic versions of these nutrients, natural forms are thought to be more bioavailable and easier for the body to absorb and utilise.
IS ROSITA RATFISH OIL THE SAME AS SKATE LIVER OIL? There is a mix of misinformation online based around skate liver oil and ratfish liver oil. It is a misconception that skate liver oil is the same as Rosita Ratfish Liver Oil. Ratfish and skate fish are from two different biological families, meaning that their liver oil nutrient profiles are rather different. Some sellers may attempt to sell skate liver oil and claim that it is the same as Rosita RFLO, however this is not true. In conclusion, the two liver oils are not the same, despite certain claims online.
