Rosita Ratfish Liver Oil

The Vikings' secret "gold of the ocean"

Rosita's wild-caught, handcrafted Ratfish Liver Oil is an ancient whole food derived from the liver of Chimaera monstrosa, also known as the ratfish. The Norwegian vikings and Scandinavian fishermen regarded ratfish liver oil as a precious gift from the sea, ranking it above all other fish liver oils.* Its rarity and exceptional properties were a major reason they called it the "Gold of the ocean."

Shipping Info

Rosita Ratfish Liver Oil is shipped without cold packs or dry ice. Please note it is perfectly fine if your bottle arrives warm or hot because the oil naturally contains more than 33% alkylglycerol content, which is a natural antioxidant. No additional antioxidants are added into the oil, as the ratfish produces and stores its own vitamin E, which also helps preserve the freshness.



Store Rosita Ratfish Liver Oil in the refrigerator or freezer.

Frequently asked questions

Ratfish liver oil is derived from the liver of a little known group of shark relatives known as the Chimaeras (Chimaera monstrosa Linnaeus; Common name: Ratfish, Rabbitfish or Ghost shark). Chimaera takes its name from the Greek chimaera, a mythical monster with the head of a lion, body of a goat, and the tail of a dragon. It is the offspring of Echinda and Typhon.

The Chimaeras are a very primitive group of fish, with skeletons composed of cartilage instead of bone, dating back for more than 300 million years. They are true survivors from before the dinosaurs, and have changed very little since. They may actually be the oldest and most enigmatic groups of fishes alive today. Truly an ancient living fossil!

The ratfish is an extraordinary fish found in all the world's oceans, close to the bottom, at depths of 300–500 meters, with a reported maximum depth of 1,663 meters. These fish are almost half shark and half ray, with smooth skin, big sparkling green eyes designed to see in the dark depths, a rabbit-like face, and a small mouth surrounded by large lips. The nose of the ratfish is studded with electric sensors able to detect the faint electrical signals given off whenever bottom dwelling prey – including crabs, snails, starfish, marine worms, urchins, clams, shrimp, and small fish – use their muscles, and sensitive enough to detect their heartbeats. Their bodies taper to an exceptionally long threadlike tail, and together with their rodent-like teeth designed for crushing the shells of their prey, has earned them the common name "ratfish."

There is very limited fishing for this species of fish, which are not a popular food source, although they are edible and their white meat is tasteful. However, following the removal of the liver, head, and all the innards, there is actually less than 10% left for use as a food source. A major reason for this is the size of the liver, which makes up a large proportion of the total mass of the fish.

The liver of the ratfish is very large, constituting approximately 60% of its total body weight, and contains an exceedingly high proportion of oil. The oil content is around 60%, but can in some instances be as high as 80% of the wet liver weight. The large oily liver plays an important role in the maintenance of neutral buoyancy.

Ratfish liver oil is one of the finest antioxidant lubricants known, having been used for guns and fine delicate instruments. Some of the old time fishermen used to save ratfish and use the liver oil as a lubricant and rust preventer. It is extremely stable compared to most fish oils and fish liver oils, and has characteristics in common with Sperm whale oil, which was used as a lubricant for the finest pocket watches. NASA even considered ratfish liver oil as a good substitute for Sperm whale oil, which was used as a lubricant in their space program.

The oils from the ratfish were also used topically, and consumed orally, by the Norwegian Vikings and Scandinavian fishermen for centuries, who regarded this oil as a rare and very special gift from the ocean, ranking it above all other fish liver oils.

Rosita Ratfish Liver Oil™ contains safe levels of the active form of vitamin A (also called retinol or preformed vitamin A). Rosita Ratfish Liver Oil™ also contains natural vitamin D3 (cholecalciferol), rather than vitamin D(ergocalciferol or pre-vitamin D).

The body also manufactures vitamin Dfrom cholesterol, through a process triggered by the action of sunlight on the skin. Very few foods naturally contain vitamin D3. Good sources include fish liver oil and fatty fish such as salmon. Other fish species including other species of cod do not contain measurable amounts of natural vitamin D3.

Vitamin D3 health benefits

Exciting research has shown that many of the body's organs and tissues have 'vitamin D receptors.' These are sites within our bodies where vitamin D is able to attach itself, and exert its positive health effects. It is little wonder therefore that research has recognized the benefit of this vitamin in promoting health effects on our hearts, immune systems and brains. A growing body of evidence indicates that vitamin D may help to:

  • Improve muscle strength.
  • Improve bone health and reduce the risk of fractures and osteoporosis.
  • Support normal blood pressure levels and prevent artery damage.
  • Reduce the risk of heart attack, heart failure, sudden cardiac death, stroke, overall cardiovascular disease, and cardiovascular death.
  • Reduce the risk of colon and other cancers.
  • Support the immune system, and as a result, reduce the risk of autoimmune diseases including type 1 diabetes, multiple sclerosis, and others; and boost the body's defenses to fight infectious diseases, such as tuberculosis and seasonal flu.

Low ratio of vitamin A to vitamin D

Rosita Ratfish Liver Oil™ has a naturally low ratio of vitamin A to vitamin D. This low ratio is truly unique among fish liver oils.

Research suggests that a low ratio may allow vitamin D to exert its full protective physiological effects within the body.

Vitamin E

Rosita Ratfish Liver Oil™ contains alpha-tocopherol, the biologically and chemically most active form of vitamin E, and by far the most abundant lipid-soluble antioxidant in humans.

The primary function of alpha-tocopherol in humans appears to be that of an antioxidant, neutralizing free radicals. Free radicals are nasty chemicals capable of damaging cells and genetic material. Free radicals are generated primarily when the body turns food into energy, and also by sunlight's action on the skin and eyes. Others are in the food you eat and the air you breathe.

Alpha-tocopherol is an important and potent cell membrane antioxidant. Long-chain polyunsaturated fatty acids are an integral part of all cell membranes, and vital for normal cell function. Free radicals are capable of reacting with these fatty acids and causing lipid peroxidation, membrane injury, and cell death. Alpha-tocopherol helps to prevent lipid peroxidation by neutralizing free radicals, preventing the propagation of free radical damage in membranes. It therefore helps to maintain the integrity of cell membranes. It also helps to protect the fats in circulating low-density lipoprotein (LDL, sometimes called bad cholesterol) molecules from oxidation. Oxidized LDL is more likely to get trapped in an artery wall and is now regarded as a prime inducer of cardiovascular disease.

Additionally, alpha-tocopherol has been shown to help maintain immune cell function, enhance aspects of the immune response that appear to decline in old age, enhance vasodilatation (relaxation of blood vessels so blood flows easily), and help prevent the formation of blood clots that could lead to a heart attack or stroke.

Yes, 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 EU 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 a proprietary process that attracts contaminants like a magnet using materials from the ocean.  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 but keeps them intact just as they are in the ratfish's liver.  Once the ratfish oil has passed through the contaminant filter, it tests below the strict EU guidelines.  It is 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.

Rosita Ratfish Liver Oil is a full spectrum fish liver oil. Unlike refined fish oils, Rosita contains many different fatty acids that thicken and separate when refrigerated. When chilled, the stearins, waxes and triglycerides may appear as particles, as a film, cloudy, or thick like gelatin. This is normal for a fresh, wild and raw fish liver oil. You may take the oils out of the fridge three to five minutes before use to allow them to evenly mix and to permit the efficient use of the dropper.

Excellent brain detoxification!

I started with 6 drops twice daily and got brain fog, which told me that it was working to detoxify my brain. I cut back to 4 drops to avoid the symptoms, and that works for me. My partner still takes 6 drops, and he is already noticing better “vision" in meditation. We will continue to take this product, along with your cod liver oil capsules, which do not taste rancid (I tested), like many apparently are.


Hi Vicki, Thanks so much for sharing your experience. How amazing that the Rosita Ratfish Liver Oil is helping to support your brain, and your husband's meditation practice. It's great that you were able to find the dose that works for your body :) And we're happy to hear you're enjoying the fresh taste of the Ratfish Oil, as well as the Rosita Extra Virgin Cod Liver Oil. Indeed, as the world's only wild caught, raw and unprocessed fish liver oils... nothing compares to their freshness! We appreciate your support, and look forward to serving you. Wishing you and your hubby the best, Vicki! Warmly. The Corganic Team

This oil is phenomenal and has lived up to all it was advertised to be. As this has been some of the worst weather in years, I am able to move around effortlessly with just a few drop.( on rye) This has become a staple in my daily regimen. I would recommend this product to literally everyone. Well worth the money. (* alert Michiganders*) own some today!!!


Hi William, Thank you so much for sharing your experience and for your kind words. We're thrilled that your Rosita Ratfish Liver Oil is helping you get through the long, cold Michigan winters.. and we totally understand as we are a Michigan-based company (brrrrr) ;) Indeed, many of our customers report that this Ratfish Oil is supportive of the joints and well being, especially when the weather is less-than-ideal. Thank you also for appreciating the value and the quality of this truly special product. We look forward to serving you, William and we wish you the very best (and some warm days ahead!) on your healthy journey. Kind regards, The Corganic Team

The product is great little more fishy than I thought, it’s great though! Ordering was easy and I got my package before Christmas


Hi Vanessa, Thanks for sharing your experience. We're happy to hear you're enjoying your Rosita Ratfish Liver Oil. It is definitely a more mild tasting oil compared to the Cod Liver Oil... but if you're sensitive to the taste of fresh fish, the Ratfish Liver Oil can still take a little adjustment. You will likely find that over time, you won't even notice the taste (or even come to enjoy it!). Some of our customers will have an orange slice after their dose, or a little sip of water, too :) We're also glad to hear you're ordering and shipping experience was optimal. We thank you for your support - and look forward to serving you. Warm regards, The Corganic Team

Pineal Decalcification Purpose

I am very happy with results as far as I can perceive; I have had, however, vertigo and headaches since Jan 5th, 2019 and do not know if it is from energy sensing or something else. My hair also has benefited from it. I am very happy.


Hi Alina, Thanks so much for sharing your experience. We're really happy to hear that you are enjoying the Ratfish Liver Oil and that your hair is feeling the love as well ; ) As to your vertigo and headaches, we recommend you check with a qualified healthcare practitioner... So sorry you are experiencing this! From our experience, vertigo is usually an inner ear infection and congestion in the head; it could be energy-related and congested energy can cause headaches as well. A little tip is to soak your feet in hot water and put ice on the back of your neck when you feel a headache coming on. We hope this info helps - and we wish you the very best. Thank you again for your support. Warmly, The Corganic Team

ratfish oil

I was trying this to decalcify my pineal gland but not sure it worked or what to expect,


Hi Thomas, You may or may not notice anything obvious or it may take some time. The Ratfish Liver Oil may offer many health benefits, decalcifying the pineal gland is just one of them. Some people may feel a little more clarity and a sense of calm or an improved focus. Others may just feel like they are sleeping better. We have gotten feedback of feeling more hormonal balance... or their skin or hair looks better. Some people may notice an improvement of their immune system overtime. The point being, there are no magic elixirs that can instantaneously 'fix' an ailment or trigger instant healing. Much depends on the diet and other supplements or medications a person may be taking. They can assist or interfere with what you experience. Keep in mind we are all unique physiologically, so each person will respond differently to any given supplement. In the meantime, know that the Rosita Ratfish Liver Oil is still delivering many important nutrients, like real vitamins A and D and a full spectrum of omega fatty acids (3, 4, 6, 7 9 and 11) plus the alkylglycerols (rare lipids). Because we are restricted from making any specific health claims, we suggest that you take a look at this article: You may find this quite interesting. Bottom line, everyone is unique and will respond differently. Even if you do not have overt obvious signs of decalcification, it doesn't mean it's not supporting your pineal gland :) Hope this is helpful. Warm regards, Karen Myers
