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.*

    Pricey but priceless

    Rosita Ratfish Liver Oil is vital for my health

    I’ve taken it for years. So I’ve gone for periods of time (weeks) without taking it to see if there is a difference in my overall well being.

    I’m 62 years into this sojourn and I work outside in S Florida full time in the hardscape and landscape business so I test myself daily.

    So the best way to explain ONE of the benefits is that when I take 15 RLO drops daily my joints are tired after a long day HOWEVER when I stopped using the oil daily what happened was my joints/back/spine gradually got to the point of feeling pain.

    I have my 88 year old mother in law in the UK taking it from the UK. She started about 3 years ago.

    We both know RLO is priceless.

    Sincerely Jeff E

    Do yourself a favor and take Ratfish Liver Oil!

    I could not talk highly enough of the Ratfish Liver Oil. I immediately felt more focused and relaxed the first day taking it. I will continue to order this. It is worth the price for the quality product you get (which is hard to find these days). Thank you, Rosita!
