Traditional supplement with a rich history
Fermented cod liver oil, also known as Cod Liver Oil (CLO), has been a standard dietary supplement within traditional European culture for centuries. The use of this oil dates back generations and was recognized early on for its unique composition full of natural vitamins and fatty acids. In this regard, the combination of fermented cod liver oil with concentrated butter oil – known as fermented cod liver oil and butter oil blend – provides additional benefits for overall wellness.
Fermentation according to traditional recipe
Green Pasture has developed its own fermentation method based on an ancient method of preparation. This special lacto-fermentation does not use heat or carbon filters. As a result, all naturally occurring nutrients are retained. Both the sensitive unsaturated fatty acids (such as DHA and EPA) and the natural vitamins A and D remain intact. This method of processing produces an oil with a distinctive light brown color, a natural result of the fermentation process.
X-Factor butter oil from grass-fed milk = concentrated butter oil blend
The X-Factor butter oil used in this blend comes from high-quality dairy. This dairy comes from cows that graze on the fertile, irrigated grasslands of the Northern Great Plains. Due to the unique climate, the grass grows fast and rich in nutrients, resulting in milk with optimal levels of Activator X – a fat-soluble substance essential for mineral absorption and strengthening the immune system.
Synergy between cod liver oil and butter oil
The power of the fermented cod liver oil and butter oil blend is in the combination. Fermented cod liver oil provides omega-3 fatty acids and vitamins, while butter oil ensures the presence of cofactors such as Activator X. Together, they form a powerful duo that naturally supports the body and mind. This synergistic action makes the supplement particularly effective and widely applicable for daily use.
New name, familiar quality
The original name Blue Ice® Royal Blend Fermented Cod Liver Oil & Concentrated Butter Oil Blend has recently been simplified to Fermented Cod Liver Oil & Concentrated Butter Oil Blend. This change increases ease of use without compromising the composition or quality of the product.
