Ever heard of the ratfish? Many people are surprised to learn this beautiful, blue-eyed, spotted fish predates dinosaurs — and that Norwegian Vikings regarded its liver oil as the gold of the ocean!

  • A concentration alkylglycerols (biologically active lipids) of up to 33%.
  • Only naturally occurring vitamin A and vitamin D. 
  • A full spectrum of omega-3 fatty acids, including EPA and DHA. 
  • Pure oil with unique lipid profile and naturally occurring antioxidants help maintain freshness.
  • So stable that nitrogen flushing is not needed.
  • Handcrafted in small batches. 
  • A mild, buttery taste.

What is Ratfish Liver Oil?

We’re the only company on the market making authentic fresh, wild-caught and raw ratfish liver oil. 

If you’re unfamiliar with this supplement, it’s the real oil contained in the cells of fresh liver from the ratfish (Chimaera monstrosa). An ancient, whole food that is straw-colored and gentle in flavor and scent. 

Rosita Extra Virgin Ratfish Oil is created using a rare, generations-old technique that naturally releases the oil from the hand-picked livers (using a gentle temperature shift). This can only be accomplished with healthy livers from freshly caught ratfish.

No heat, chemicals, steam, metals or mechanical pressure are ever used in the creation of your oil. You can read more about Rosita’s heat-free and chemical-free patent to purify its oils and preserve their inherent nutrients, here

This all means your ratfish oil maintains the same form and nutritional composition that nature gave it, without being altered in any way. 

Who should consider adding ratfish liver oil to their supplement routine?

Rosita Ratfish Liver Oil appeals to a wide variety of health interests:

  • Real foodies searching for a rare and unique nutrient profile. 
  • Those looking for a completely natural supplement that’s high in alkylglycerols.*
  • Families with children on the spectrum (especially those with taste sensitivity to fish).*
  • Spiritual people who want mental clarity and to decalcify the pineal gland (third eye), which supports meditation, relaxation and rest.*
  • Anyone striving to improve and support their overall health, including the brain, and immune and circulatory systems.*

    Dropper

    Loved the oil. But the dropper is cheap and doesn’t work well. I’ll probably have to buy a separate dropper. I had this problem 2-3 years ago. The 10ml bottle is fine but would rather get the 50ml. Except for the bottle dropper.
