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.*

    Miracle in a bottle

    This product has changed my life. I cant rave enough about the benefits. Sharper, quicker mind, hitting 25% -30 % Rem sleep nightly, went from 225 readers to 175 with 1 large bottle, less hungry, better skin, nails and hair. I ended up starting with 5 drops, had a bit of a headache for about 2 weeks and some ear fluid in my canals. Just delt with it cause I knew something was happening. I broke my Temporal done about 10 years ago mountain biking, then I jumped to a vile a 2x a day. The results started to go at a faster pace. Finished my bottle within 3 1/2 months. On the a new bottle now. i cut back to 1/2 a vile daily and the REM sleep is still at about 28% nightly. The biggest change for me is my brain. I think so much more clearly with speed. My dreams and human sense is back to what it used to be in my 20's, the intuition is what I mean. Just knowing.

    This stuff is a wow. Will be taking it for life

    ⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️⭐️ its a 10 star product!

    Felt effects first dose!

    I have been taking the cod liver oil for about a year and a half , which I enjoy very much. I wanted to try the other products so I ordered ratfish oil and bee bread. I took both today around 1pm and WOW, I felt great - I ended up staying at work an hour longer because I had so much focus.. I quit drinking caffeine 7 days go and I have been feeling a little bit off from the withdrawal but this combo really woke my brain back up and it was only my first day.. excited to have my husband try it out and see the continued benefits!
