High Vitamin Butter Oil has been a staple in the supplement market since the Wetzel family launched Green Pasture in 2000. Moreover, the Vitamin K-rich superfood has been hailed by Dr. Weston A. Price and his followers as a complement to cod liver oil since 1930. It is no wonder that Green Pasture Butter Oil, along with Green Pasture Fermented Cod Liver Oil has been one of our most popular products for many years. And when Rosita Real Foods Extra Virgin Cod Liver Oil hit the market, we quickly added it to our product line as an alternative to the Green Pasture line. And in 2021 we brought in Dropi extra virgin processed cod liver oil from Iceland, another high quality cod liver oil that is processed without heat or chemicals to retain all the valuable nutrients.

In 2023, Is High Vitamin Butter Oil Still the Best Source of Vitamin K2?

In November of 2015, Sally Morrell of the Weston A. Price Foundation sent samples of several known sources of Vitamin K2 to be tested by VitaK, an independent laboratory. The results surprised the entire industry–High Vitamin Butter Oil was not the best source of Vitamin K2…not by a long shot.

And the Winner is…Emu Oil!

When Walkabout Health Products debuted their flagship product in 2013, we knew there was something special about their unprocessed, untreated, unpasteurized Emu Oil. Once our customers started using it as a capsule supplement and a topical oil, the rave reviews poured in. That’s why we were thrilled to see our trusted Walkabout Emu Oil listed as the richest source of Vitamin K2 M-4–with more than 5 times the Vitamin K2 as Green Pastures Butter Oil!

Does That Mean that Green Pasture Butter Oil is Unnecessary?

Of course not! The results of the VitaK study revealed that Walkabout Emu Oil was a better source of Vitamin K2 than High Vitamin Butter Oil. However, Green Pasture’s Butter Oil has an array of health-boosting benefits that make it a great fit for certain situations.
