No, you can’t ferment cod liver oil or skate liver oil, but you can ferment cod/skate livers, and that is exactly what we do. In naming the product Fermented Cod Liver Oil and Fermented Skate Liver Oil, we are simply paying homage to the extraction method.

We have not found any research yet that can answer this question. Considering the fact that most antioxidants have color, it would suggest that there at least is a correlation between color and health benefits.

Yes, there are low levels of natural trans fats in cod liver oil. They are an important part of the cod’s natural composition. You can read more about this in Fermented Cod Liver Oil: What Do The Scientists Say?

Different types of planktons are the source of most vitamin D in the sea. Read this article, Fat-Soluble Vitamins, Especially Vitamin D Variation in Marine Fish to find out how this important vitamin ends up in bigger fish.

The exact amount of fatty acids will vary from batch to batch. Below you will find a conversion to calculate an estimated amount.

5ml = 5g = 5,000mg = 1 tsp.

X = the amount of Fermented Cod Liver Oil product you take
Y = The approximate % of the fatty acid found within the product, which is 10%.
X mg x 10% [Y] = mg of intake

So , how many mg of DHA am I getting if I take 1 tsp of Fermented Cod Liver Oil each day?

5,000mg x 10% = 500mg of DHA per tsp.

Some people are more sensitive to new things and react with adverse effects. If you are experiencing digestive issues, we suggest that you stop taking Fermented Cod Liver Oil and check with your health practitioner.

Dr. Weston A. Price identified numerous benefits of concentrated butter oil, which he referred to as “high vitamin butter oil” and described in his 1939 book, Nutrition and Physical Degeneration. Even more significantly, Dr. Price came to realize that the special concentrated butter oil worked best in synergy with cod liver oil. “One without the other did not do his patients justice, but the two together worked like magic.”

Green Pasture Products established this blended product line to recreate this magical synergy and honor Dr. Price’s discovery. The line combines our concentrated butter oil with our fermented cod liver oil in one convenient and easy-to-take product.

Roughly 2/3 Fermented Cod Liver Oil and 1/3 Concentrated Butter Oil in the blended products. 

In 1939 Dr. Weston A. Price published his book, Nutrition and Physical Degeneration. In this landmark book he introduced the benefits of concentrated butter oil. He discovered what he referred to as fat-soluble “activators”, which seemed to improved absorption of nutrients in nutrient deficient individuals.

We at Green Pasture Products have revived Dr. Price’s discovery. We have replicated his careful farming and production methods so that we can share with you this wonderful nutrient-rich oil.

We are very selective in sourcing our butter oil. Please visit Our Partners page to learn more.

Dr. Weston A. Price first described the nutritional value of butter oil in his 1939 book, Nutrition and Physical Degeneration. Based on his pioneering work, we started over 15 years ago making this nutrient-rich product. Our blog, Celebrating 15 Years of Making Butter Oil tells this story.

We get our skate livers from fish that have been exclusively wild-caught in the Bering Sea/Aleutian Islands region of Alaska. View Our Partners page to learn more about the specific company we partner for our fish liver sourcing.

Skate is a cartilage fish that cannot grow bone. It is very closely related to sharks but is flatter in shape. The skate livers are sourced from the same region as our cod livers. We use the fermentation method to extract oil from both cod and skate livers. Our skate liver oil and cod liver oil both contain naturally occurring vitamins and omega fatty acids.

We recommend that energetic or biofeedback testing be employed to help answer this question. We have found that some simply do better with skate oil than with cod liver oil. Generally speaking, taking a little bit of both is best.

Skate is a cartilage fish, it cannot grow bone. Our understanding of how vitamin D and calcium are involved with cartilage formation is not yet fully completed. Our perspective is that each person is unique, and no two people can make any one conclusion without first investigating.
