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 method to purify our 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).*
  • Anyone striving to improve and support their overall health, including the brain, and immune and circulatory systems.*

    Just get it!

    I wasn't sure if I would like Ratfish Liver Oil (sounds strange, hadn't heard of it before), but I knew that I liked Rosita's other products and the benefits sound good, so I bought the little one to try. Now I'm re-ordering the big one! It's great. Go for it!

    Really happy with your products

    Amazing quality oil, I can feel its benefits in a few days. I only have a request, I purchased the large sized and I wish it wasn’t a dropper ( it gets messy). Maybe you could offer a little larger size with no dropper.
