2018 Review: Blue Ice Fermented Cod Liver Oil and Butter Oil Capsules

By Lace / April 5, 2018

Product: Green Pasture Blue Ice Fermented Cod Liver Oil and Butter Oil Blend Capsules

Cheapest place to buy: Amazon

Size: 120 capsules = 60 servings @ 2 daily

Price: Around £34/ $40

Customer Rating: 4.5 out of 5 stars



“Blue Ice Royal blend capsules contain two-thirds fermented cod liver oil and one third X-Factor Gold Concentrated Butter oil. Fermented cod liver oil is made in small batches with extraordinary care. We ferment livers from fish that have been exclusively wild caught in the Bering Sea and Aleutian Island regions of Alaska.”

Although, interestingly, the bottle says the cod liver in the product comes from a fishery which has been independently certified to MSC standards for well managed and sustainable fisheries. A fishery isn’t exclusively wild caught… Conflicting information but clearly stated on the label nevertheless.

This product is described as a raw, unadulterated, whole food with no additives. Green pastures boast frequent 3rd party testing on the product to ensure purity.


Fermented cod liver oil, raw butter oil concentrated through centrifusion, unbleached beeswax (as thickener) plant cellulose (capsules). Contains cod (Gadus macroephalus Pacific cod), Milk.

Suggested serving is x2 capsule daily.

Nothing suspect about that ingredients list and the serving suggestion equals about half a teaspoon daily. Admittedly, I  take 6 a day because I’m actively working on remineralising my teeth and pass the nutrients to my son who’s currently breastfeeding.

What do customers say? 


Overall, customers are rather pleased with this product with an average customer rating of 4.5 out of 5 stars on Amazon. Let’s take a look at what buyers liked about this Blue Ice product and what they weren’t so keen on.

The Yays

79% of reviews on Amazon UK are 5 stars with customers reporting marked improvements in various areas of their health. Buyers report taking the supplement significantly reduced their tooth sensitivity and joint pain. Other positive benefits experienced by customers include improved sight, brighter eyes, clearer complexion, healthier gums, reversal of tooth decay and improved immune function. These capsules are regarded as easy to swallow with no aftertaste and many customers highly recommend them to others.

The Nays

The price. It’s rather expensive and it hasn’t gone unnoticed by customers. Taking more than 2 capsules a day makes this product even more pricey, I know,  I’m feeling it as I take 6 daily…eek! Some users, myself included, find the capsules smelly with others, also like me, find their kids hate the taste. A number of customers noted no remarkable difference in their health or well-being from taking the supplement, it’s unclear if they had specific ailments they hoped to see a difference in. If you’ve researched FCLO already you may be aware of the current debate around Green Pasture fermented cod liver oil) more on that shortly). This debate is cited as a reason for leaving a bad review without discussion regarding personal experience of the product.

The good, the bad and the smelly

So, what’s this debate all about? Well,  it centres on whether Green Pastures fermented cod liver oil is “rancid” and the species of fish used to make it. Claims have been made about GPs cod not actually being cod. Oh. My. Cod! Can you believe it?! Sorry, couldn’t help it.  Anyway, It’s he said, she said sort of game and from what I understand, those making the claims have financial ties with a competing company who produce Rosita Extra Virgin Cod Liver Oil (EVCLO). So, all may not be as it seems, dear Watson. Rather, interesting stuff eh? I mention this because it played a part in my decision to buy the product in the first place. To date, I have found no real answers so I applied innocent until proven guilty and based my decision on other factors instead; customer reviews and testimonials for the most part.

Why I chose to give this product a go

My teeth need remineralising and my plan was to kill two birds with one stone with a combined cod liver oil and high vitamin butter oil capsule. I’m reading ‘Cure Tooth Decay’ by Ramiel Nagel and discovered green pastures blue is recommended in the book. My research on the product turned up positive customer reviews, especially where teeth were concerned with many putting their reversal of tooth destruction down to Green Pastures Blue Ice. There doesn’t appear to be any other company offering a similar combined product so I thought I’d give it a whirl based on the positive feedback. Fermented cod liver oil has a pretty bad rep for taste so I opted for capsules to avoid the taste as far as possible. I hoped I’d be able to mask the taste if I opened the capsule to give to my children. I can tell you now that idea was an epic flop. But first things, first.

Tried and Tested: Was it any good?


green pasture blue ice capsulesFirst impressions: The bottle is dark to protect the liver oil from light, secure and robust with clear labelling containing fairly large smooth capsules. I find the capsules easy me to swallow with water but they do leave a funky taste in my throat. Taking them with food significantly reduces the aftertaste and I’m thankful for that! My children don’t find the gel inside the capsule palatable but they tolerate it better if it’s covered in cinnamon. However, I can assure you FCLO time isn’t their favourite time of the day. I don’t blame them either it’s not particularly nice at all.

I feel my dental health is improving and I am seeing positive improvements in our teeth since we started taking this product. We are implementing the protocol as the book outlines so this may well be the result of all of these things combined.

Weighing it all up

  • Pricey
  • It smells
  • The ongoing Green Pastures FCLO debate may be off-putting
  • Some buyers noted little to no noticeable benefit from taking it
  • The aftertaste and fish burps if you’re unlucky like me!
  • Easy to take
  • People swear by GP blue ice combo for positive results with remineralising teeth
  • Natural source of vitamin A, D and Activator X (ya’ll gotta read the book, it’ll all make sense then)
  • Buyers report numerous benefits from taking Blue Ice from brighter eyes, healthier teeth and gums and reduced joint pain
  • Combined with high vitamin butter oil it’s essentially two products in one
  • Recommended in Cure Tooth Decay by Ramiel Nagel (it’s  brilliant!)
  • Lots of positive customer feedback

The bottom line

The idea of Green Pastures Blue Ice is a great one, essentially being two products in one and represents good value. As the FCLO debate goes I don’t know the answers, fermentation of food has been around forever, so I don’t think fermentation in itself is a bad thing. After all, many nutrient-dense foods are fermented like sauerkraut, kimchi and kefir. There’s a lot of information out there and I’ve read plenty from both sides, the truth is I don’t know and there appears to be much more to all this than what meets the eye.

For me, I chose to try Green Pastures Blue Ice because it’s been a hit for hundreds of customers with consistently positive reviews. Buyers report great results from taking Blue Ice FCLO, surely they can’t all be wrong?

Green pastures capsules are great for reducing the full-on FCLO taste but do beware of possible funky aftertastes! I do feel I’ve benefited from taking this product and I would buy again despite the current debate, although I’ll be watching for updates and new independent information could change my opinion. Overall, I appreciate this product and I think it represents good value for money if you’re looking for a combination blend of FCLO and butter oil. I do hope you’ve enjoyed reading and have gained something useful from it.

Yours in fermented fishiness,

  • Lee Ann says:

    Thank you for this information.
    I am glad I came across this. My daughter has had issues with her teeth being very sensitive since having to have her jaw wired shut (she had to have her impacted wisdom teeth removed and her jaw was broken during the process), for 2 months, so I am not sure if this was the cause, but I really want to find a product that actually DOES what it says.
    I can not wait for her to try this, and I really hope it works for her and gives her some relieve.
    Thank you

    • Lace says:

      Hi Lee Ann, I’m so sorry to hear what your daughter had been through, sounds really tough. It’s certainly not too late to improve her dental health and starting her of fermented cod liver oil would be an excellent move. If she has any pain I’d like to recommend adding lugols 5%,iodine either applied directly to the tooth/teeth in question or brushing/swishing with a few drops. It’s fantastic for dental pain and killing infection. All the best to you both. 


  • I couldn’t live without my fermented cod liver oil! Thanks for the review! I take it as part of my daily regime. I will certainly be trying out this brand next time I need to replenish my supply.

    • Lace says:

      Ah, another fan of cod liver oil, fab! Which brand are you currently taking Steven? When you restock if you do decide to try Green Pasture I’d love some feedback. Hope to catch up with you soon.


  • AJ says:

    Cod liver. Very interesting. The smell itself I’m sure is weird, but for the benefits I believe its worth it hands down. Even though they are a bit pricy, I think thats typical but also normal, and from what your saying, super worth it. Great post.

    • Lace says:

      Fermented cod liver oil is what the Vikings swore by for good health! I’d agree with you that the benefits of taking it, despite the slight pong,it’s definitely worth the price.

      Thanks for stopping by AJ.

  • Jackie says:

    Hi Lace!!! Just went through your website, loved the name FRUGAL BY NATURE. When you are taking those Cod Liver Oil capsules, have you noticed any reactions on you or your children, like heartburns or smelly burps? Some years back, I tried a similar product and my body didnt adjust to it well, I even developed a very disturbing throat swelling after a couple of weeks of taking the capsules. Where can I find more info about these ones? Thank you!!!!

    • Lace says:

      Hi Jackie! Thank you! I’m sorry to hear you had a bad experience with cod liver oil in the past. What brand did you take previously? Fishy burps are an issue for me with Blue Ice but many others seem not to have that problem. As mentioned in the post, this problem is overcome if I don’t take on an empty stomach. For more information on Blue Ice head over to Amazon or Green Pastures website. If there’s anything else I can help with just shout 🙂 

  • Tammy says:

    Thank you for this Blue Ice Royal blend capsules review. I’ve tried many fish-type supplements and always have the dreaded fish burps, but I could use these for possible better eyesight? I have readers all over the house and would love a natural way to improve my closeup vision. I miss the 20/20 days! Better immune function is also a plus, thank you!

    • Lace says:

      Hey Tammy, you’re welcome. What brands of fish oil have you tried? Fish burps were a downside to Blue Ice for me but the benefit of the oils outweigh that I think. If you want to support your eyesight this product is a great option. Better immune systems are definitely a bonus too.

      Thanks for your comments, I love hearing from my lovely readers 🙂

  • Darren says:

    These capsules sound fairly expensive, but then that’s pretty common in health and wellness products.

    I’m looking for something for joint pain, such as my back and an arthritic knee from an old injury that’s been playing up a lot of late.

    These capsules sounds really good actually. If they help, then they’ll be well worth the price tag. I’ll give them a try and see how I go.

    • Lace says:

      Hey Darren, sorry to hear you’re suffering pain at the moment. Indeed fermented cod liver oil is great for joint health and arthritic pain. If you haven’t already look into emu oil and osteopathy too as I do believe they may be able to help you also.

       Like most things that are good for us, these are a little costly but if we are healthy then life becomes cheaper because we’re not slaves to big pharma and toxic fake food. I’d love to hear how you get on with the blue ice fermented cod liver oil when you’ve tried it. 

      I hope you are pain free soon,


  • Amazon LaShaun says:

    This was a good review. As expected, the price found it’s way under the negatives. It seems like that happens with just about everything that is healthy these days, but I can’t ignore that 79% user approval rating. It just might be worth it. We only get one body, after all. Keep up the great work.

    • Lace says:

      Thank you for your comments LaShaun. With so many toxic products being subsidised by government it certainly makes healthy options seem extra expensive. The customer reviews certainly speak for themselves and you’re absolutely right. Our body is our home, if we look after it and it’ll look after us 🙂 

  • I am always looking for new natural supplements to help with health issues. I have not heard of this product, until now. It looks very interesting, especially for teeth help. I am sure we should all look at it for teeth re-mineralization. I will definitely be checking it out.
    Thanks for the great review.

    • Lace says:

      Hey Curtis, I’m glad you found the review useful. Fermented cod liver oil has great feedback when it comes to remineralising teeth and improving health. I hope you enjoy the benefits of using this product. Thank you for your stopping by!

  • Penelope says:

    This might sound a little gross, but do fermented cod oil supplements leave you with really nasty burps? I was trying to think what the negatives would be for this supplement and that’s honestly the first thing that came to mind. The benefits sound pretty undeniable, though – I know people who swear by this stuff.

    • Lace says:

      Yes, Penelope, the fermented cod liver oil does give a case of of the dreaded fish burps. Take them with food and you’ll be reaping the benefits with the fishy aftertaste! It’s really great stuff. Are you currently taking a fish oil supplement?
