Experience the purity of the Norwegian fjords in every drop. Rosita Ratfish Liver Oil is carefully extracted from wild ratfish, preserving its natural blend of nutrients and freshness.

Handcrafted in small batches, this extra-virgin oil is a rich source of omega-3 fatty acids, including EPA and DHA, which contribute to the normal function of the heart.

With naturally occurring vitamins A and D, plus unique alkylglycerols and active lipids, Rosita Ratfish Liver Oil offers gentle support for your everyday wellbeing.

Born in a home kitchen in Hertfordshire, Rollagranola was founded by Robin Longhurst as a response to ultra-processed breakfast cereals dominating store shelves. With a mission to prioritise whole food ingredients and functional nutrition, he developed recipes packed with nuts, seeds, and superfoods—no added sugar or empty carbs. Rollagranola now offers a range of baked granolas designed to energise, satiate, and nourish—whether used as breakfast, snack, or topper. Every blend balances flavour and fuel, turning the morning ritual into a moment of mindful nourishment.
