Product Information

Dr. Weston A. Price D.D.S. discovered that cod liver oil combined with butter oil was more beneficial than either one on its own. Based on this, we have created this blended product inspired by him. It is a combination of our Fermented Cod Liver Oil and our Concentrated Butter Oil. This blended product is nutrient-rich and full of healthy fats to boost your oral and overall health.

Learn more about the Fermented Cod Liver Oil and the Concentrated Butter Oil in this product on their product pages.

The fermentation process used to extract the oil is such a gentle method that it shields the natural antioxidants. View the scientific discussion about the natural antioxidants Polyphenols.

Frequently Asked Questions

Why does the Blue Ice Royal product line blend concentrated butter oil and fermented cod liver oil?

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 the Blue Ice Royal product line to recreate this magical synergy and honor Dr. Price’s discovery. The Blue Ice Royal line combines our concentrated butter oil with our fermented cod liver oil in one convenient and easy-to-take product.

    I take Green Pasture’s FCLO/Butter Oil blend. Interestingly enough, I just found out I actually like the taste of the unflavored gel compared to the cinnamon flavor! Maybe it’s my Norwegian blood.

  3. Bryce R.

    My favorite Green Pastures product is the fermented cod liver oil/ High vitamin butter oil because of that X-Factor related by Price.

  4. Judith G.

    My family has been taking your Blue Ice Royal Butter Oil/Fermented Cod Liver Oil Blend for years and have enjoyed good health and energy

  5. Tara K.

    My son has loved the chocolate butter oil/FCLO blend since he was 1! That, along with a diet that includes grass-fed butter, raw milk, and pastured eggs has kept him healthy and cavity free up to this point. He’s now 6. We’ll keep buying this great product!

  6. Sue R.

    My favorite Green Pastures product is the Blue Ice Royal Fermented CLO concentrated butter oil blend capsules. They are a great tasting and convenient way to get CLO into my diet. I have been using this for years and am very happy with the product.

  7. Victoria R.

    I have 2 grown up kids, 28 and 19 years old. They’ve been taken cod liver oil/butter oil capsules for at least 10 years now, since I first discovered the great value of this product. They’re full of energy, succeeding in school and work, and I’m really grateful to the company for this awesome gift of life and health. By the way, me and my husband also taking it religiously.

  8. Jenny S.

    My favorite product is fermented cod liver oil concentrated butter oil blend capsules! Every time I have ever tested this with my holistic practitioners it comes up positive for me on the Asyra scan and muscle testing.

  9. Susan D.

    My favorite Green Pasture products are the straight up unflavored FCLO and the FCLO/HVBO capsules (for those family members that don’t enjoy the liquid). I have seen definite improvements in skin problems soon after starting Green Pasture products – hooray!

    Best brand that is worth your money! The best benefits to my health and my teeth!

  11. Marina (verified owner)

    We all really like the CLO! My children have it every day!

    I love the Fermented cod liver oil and butter oil blend. It is a very good source of vitamins and nutritions for me and my kids.

  13. CDavito

    This is my first time ever purchasing. I learned about this product from Ramel Nagel’s book, “Cure tooth Decay”. Personally I have never had a cavity but a recent checkup at the dentist for my 3 1/2 yr old daughter showed three near cavities. I was discouraged and would prefer to avoid the special flouride treatment they are pushing to MAYBE prevent further decay (80% effective). The book was recommended by my sister to see about reversing the decay. I am encouraged by all of the positive reviews!

  14. Jenny

    The best cod liver oil supplement on the market. I’ve seen an improvement in my skin (specifically keratosis pilaris) when taking this product regularly. I take it followed by water and a small slice of lemon (rind and all) and there is little to no fishy aftertaste.

  15. Amy N

    The fermented cod liver oil/butter oil is a great product I’ve been using for years. I feel it is a really important part of my health routine. My favorite flavor by far is the chocolate cream. I don’t even have to use a chaser anymore!

  16. Dan

    First let me say how much I love Green Pasture and the friendly, professional staff! I have a wellness center in Michigan with a small retail outlet for natural supplements and healthy lifestyle choices. My clients love the Royal Blend Gel. One client remarks that she has not needed to use skin lotions or moisturizers since including the Royal Blend in her diet. The taste is well received, too. I recommend the Green Pasture FCLO as a dietary supplement period, but it is especially good in our northern climates where we receive less sunshine for the vitamin D. Thank you Green Pasture.

    This gel is so delicious to me I could eat it all up at once, but I really shouldn’t do that. I keep it in the fridge and it turns solid, like chocolate ice cream… yum! I look forward to taking every day! I also love the cod liver oil with orange flavor. It’s not unpleasant at all and I actually like the taste!
