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.

    This is a great product. It keeps me feeling strong in the cold months. I really like the gel consistency.

  2. Duncan O. (verified owner)

    My toddler loves the cinnamon flavor. Has it as his treat with his breakfast.

  3. Kaylee M. (verified owner)

    I love how it keeps me feeling healthy, bright, and strong especially in these covid times! I have had the cinnamon, and I’ve been enjoying it so far. I don’t taste any fishiness. Tastes like big red gum. My skin is so soft and smooth when I keep up with this too! I don’t need any external/topical products at all; my beauty regimen is entirely from the inside out! 😀

  4. Nicole L. (verified owner)

    Chocolate is good but I prefer cinnamon which is excellent. I ordered chocolate by accident.

  5. Natalie H. (verified owner)

    came across as recommended by the WAPF. we love taking it as part of our daily routine, and give it to our toddlers also. helpful for teeth, reducing allergy symptoms, and maintaining health during cold michigan winters!

  6. Natalie H. (verified owner)

    love it! great for remineralizing teeth postpartum, reducing allergy symptoms for my husband, and for both my toddlers.

  7. Karen S. (verified owner)

    Can I give this 10 stars because the fermented cod liver oil and concentrated butter oil is a winner. We like the cinnamon and take it every morning. It provides energy throughout the day. The product quality is excellent and Green Pasture is a great company to order from. Thank you!

  8. Candice C. (verified owner)

    I have been taking the ferment cod liver oil and butter gel for quite some time now. I can definitely tell a difference with the health of my teeth. I prefer the cinnamon flavor gel while my daughter prefers the capsules.

  9. Anthony V. (verified owner)

    Helps to keep m my family healthy with omega 3s, vitamin A, and D

  10. Jocelyn B. (verified owner)

    I found out about this product through a book on holistic dentistry and Weston Price`s research. I have been using it for over a year now and I love it. The unflavoured gel is great, and I find that my teeth are getting stronger and my gums are looking healthier. Definitely recommend!!

  11. Kaylee M. (verified owner)

    Love the effects! My skin is ridiculously smooth, soft, and hydrated; I don’t need to use topical products because my skin care routine is from the inside out with this magical blend. Teeth sensitivity goes away when I keep up with this. Tried the cinnamon flavor, no fishy taste. But I don’t think I’m much of a cinnamon fan so I’m excited to try out the other options. Will definitely be resubscribing one flavor or the other! So grateful this product exists and I can buy it!!

  12. Alberto H. (verified owner)

    I bought the unflavored gel and I really liked it. I took very little each day; it’s nutritionally concentrated so I did not need to take much each day. I am grateful that Green Pasture is passionate about providing clean and delicious nutritionally dense food. Thank you, Green Pasture family 🙂

  13. Tracy B. (verified owner)

    We love this product. It has made our teeth stronger and an important part of our cavity elimination protocol.

  14. Margaret G. (verified owner)

    Love this Cod Liver Oil. It makes me feel energetic and great!

  15. Emily A. (verified owner)

    I just started taking this cod liver oil & butter blend. I’m about done with my first jar & have been pleasantly surprised how easy it is to take. The taste isn’t pungent & no upset stomach. I can’t wait to see my long term benefits

  16. Elizabeth O. (verified owner)

    I love this cod liver oil+butter blend! It does have a slightly fishy taste/aftertaste, but seriously, for what it is, it is pretty darn mild. I decided I’d be willing to accept that for the benefits, and I was pleasantly surprised by the mildness. When I have heavy cream on hand, I just have a spoon of that afterward, and it wipes out any fishy-ness. (Guessing the fat in the cream binds well with the fat in the butter oil. Anyway it’s effective!) Or I eat chocolate right after and that handles it. 😉 All good! Thanks, Green Pasture! I’m actually looking forward to my next dental checkup—never thought I’d say that!

  17. Joseph A. (verified owner)

    I have been using the FCLO Blend for years and it is hands down the best product of its kind on the market in my opinion. It is like WD40 for the joints 🙂 Thanks for making such a great product!

  18. Heather S. (verified owner)

    I have been taking the Blue Ice Fermented Skate Liver Oil and the Cod Liver Oil and Concentrated Butter Oil – Cinnamon. Wonderful to take. Looking forward to seeing how I feel over the next few months.

  19. Ava F. (verified owner)

    I’ve been taking the Fermented Cod Liver Oil With Concentrated Butter Oil for years. I particularly like the cinnamon flavor. When people ask why I look so young for my age, I tell them I owe my good health to Green Pasture. That stuff is pure magic.

  20. Kim G. (verified owner)

    My husband and I have been using GP’s fish oils for about 10 years now, after meeting some of the family at our local WAPF chapter meeting. Their demonstration was very educational, and if you ever get a chance to see them give it, it’s well worth it.

    So we started on the plain fish oil for about 9 years- but now we love the convenience of their fish/butter oil blend. My husband and I used to take the plain fish oil with butter, but we decided to try out the blend for a family member before ordering it for her. (We wanted to make sure we thought she’d find it tolerable. It worked.) It was so much simpler to take the blend! I even tried making my own blend and I couldn’t mix it well enough to keep from being separated. We finally realized it was worth the extra cost to just get their fish/butter blend. Then we never forget to take the butter with it, we are more easily consistent with taking it, it’s less messy, and it tastes nice, too.

  21. Rebecca M. (verified owner)

    This stuff is amazing. I like the fact that I am getting vitamin D through a whole food.

  22. Kristin R. (verified owner)

    Within the first couple of days of having the fermented cod liver oil and butter oil blend cinnamon gel, my teeth stopped being sore. A few days later, my teeth felt stronger and more solid in my gums. My gums also started to look healthier. After a couple of weeks, I noticed that my mood improved on the days that I had some. I was worried that there might be a fishy flavor, but I keep mine in the fridge and have a half teaspoon everyday. I’m only sorry that I missed the sale by a day, otherwise I would have ordered more! I started out with the capsules, but went to the gel for a better bang for my buck. If I skip a few days, I notice a difference in how I feel, both mood-wise and teeth-wise.

  23. Amy Q. (verified owner)

    I bought the cinnamon flavor and it’s pretty good. I heard really good things about this product and I’m hoping it will strengthen my teeth.

  24. Anna R. (verified owner)

    I have been buying this blend for my family for about six years now, with great results! If I ever have an issue with a delivery, they always fix it right away, and then some. Highly recommend!

  25. Amna I. (verified owner)

    A must have for strong and healthy teeth. So glad to be able to get an authentic product. Thank you for your efforts.

  26. Karen S. (verified owner)

    I’ve been using the cod liver & butter oil cinnamon for several months now. I love the taste, the quality and the health benefits it provides!

  27. Vivian C. (verified owner)

    Our family have been taking fermented CLO from green pasture for over 10 years now and I think it has made a big difference for my teeth. I used to get diagnosed with a new cavity every time I go to my dentist, but I don’t think I’ve had a new cavity for many years now. None of us can tolerate the taste but fortunately we are all good at swallowing pills so we keep our CLO in the freezer and swallow a chunk of it as though it’s a pill.

  28. Jane D. (verified owner)

    Been ordering the cinnamon tingle for a long time now, it never disappoints. Keeps me very healthy and happy to support an American company.

  29. Sha Y. (verified owner)

    Great taste and super nutritious. Have been taking this blend for years and love it!

  30. Lori N. (verified owner)

    I love the taste of this one over the chocolate. Chocolate is okay, but somehow the fishiness comes through more than this one, at least to me. I barely taste anything but cinnamon. Love the product and believe it is worth the money.

  31. Jodi E. (verified owner)

    We tried these gels, both chocolate and cinnamon, because of a sale and after reading reviews about how good they were and how kids enjoyed them. So, I opened up the chocolate and gave my son a small spoonful, expecting him to ask for more… but was I wrong! It tasted like fishy fish dipped in chocolate. The cinnamon was a bit more palatable but still nothing I was wanting to taste more than once.
    We will stick to the capsules. Unflavored, easy to swallow and packed with rich nutrients.
    I gave two stars because customer service was helpful as one of our jars was broken upon arrival. But no stars for flavor and experience of having tasted them.

  32. William S. (verified owner)

    I’ve been taking FCLO/Butter oil blend for over 10 years and would not go a day without it. It has the X-factor (Vitamin K) from the butter oil that is needed to get Vitamin D into your cells. Plus, it contains Vitamin A that is vital to good health.

  33. Ivan C. (verified owner)

    Love this product. It’s very good for keeping teeth healthy

  34. Marjorie G. (verified owner)

    I have been taking the Cinnamon-flavored Fermented Cod Liver Oil Butter Oil Blend daily for years. It is my favorite cod liver oil. It has the X-factor that Weston A. Price recommended. I also enjoy the taste. I recommend it highly.

  35. Debra L. (verified owner)

    Wonderful product. Love the combo and I feel great taking it for my oral health

  36. Mihran B. (verified owner)

    This is an amazing product. As others have said, look into Weston A. Price’s research to learn more about the benefits. I personally have had greatly increased dental health in the last 10 years of taking the cod liver oil/butter oil blend and I know people who have experienced other health benefits as well like overall better sense of well-being. The taste of the unflavored variety is not bad at all if you’re used to fish oil, while the chocolate and cinnamon flavors cover it up very well if you want to avoid the fishy taste.

  37. Terri S. (verified owner)

    I like the way I feel taking the fermented cod liver oil butter oil blend. I am going to have to try capsules though. Cinnamon flavor is doable. I just finished my first jar and ordered the chocolate to try. Ugh….I am not a fan of fish, so this is a trial for me. I have to eat something after or it is unbearable. I know the product is great, not sure I can get through the bottle of chocolate though. Be aware, you may have to power through.

  38. Jeanne R. (verified owner)

    Great product. Tastes great. Entire family takes daily

  39. Daniel K. (verified owner)

    I suggest looking up Weston A Price research, yes a Dentist.. Go to a site with his research Pictures. See what a difference this combination of ingredients makes. Forget reading the studies. The pictures tell all you need to know. This stuff is miraculous, especially during formative years. Another miracle is that it exists, and you can just “Click & Ship”.What are you waiting for? I like the cinnamon flavor. My hat is off to Green Pastures. Daniel K.

  40. Lindy C. (verified owner)

    Shipping was fast and packaging was great! We are using the chocolate. One of my children finds the cod flavor very strong so I will probably buy capsules in the future.

  41. Andreas L. (verified owner)

    Awesome, convenient and tastes great! I purchased the cinnamon flavor btw.

  42. karla c. (verified owner)

    Green pasture fermented cod liver oil and concentration butter oil blend is something we will always have in our home. My children are healthy and happy. I use it for absolutely everything and it always makes us all better in any situation. So great full to have in our home!

  43. ksedeniussen (verified owner)

    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!

  44. Dan M.

    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.

  45. 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!

  46. 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.

  47. 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!

  48. petra t. (verified owner)

    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.

  49. Marina W. (verified owner)

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

  50. Chelsea B. (verified owner)

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

  51. 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!

  52. 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.

  53. 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.

  54. 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.

  55. 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!

  56. 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

  57. 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.

  58. Joelle M.

    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.
