  • 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?
