The Absolute BEST Cod Liver Oils

What is the BEST cod liver oil? This is a question I get asked often. There are so many cod liver oils on the market, but many of these brands only use about half cod liver oil- the other half is made up with synthetic A and D! Yuck-that defeats the purpose of using cod liver oil if half of the nutrients are man-made. So let’s talk about why cod liver oil can be so amazing, and which brands are actually great.


Cod Liver Oil has REAL Vitamin A

Autoimmune disorders, leaky gut, inflammation, ATP energy production, food intolerances, and more are connected with vitamin A. Retonic acid impacts about 500 different genes!! This article is probably one of the best I have ever come across. Vitamin A is so important for our healing process, but we do need to go slow with it and support our livers!

Vitamin A is a crucial nutrient needed to heal from copper dysregulation. It is a prime part of creating ceruloplasmin. (Source-PubMed) Most A is stored in the liver so blood tests can’t be very effective in telling us our A stores.  Low ceruloplasmin in the blood and low potassium on the HTMA are good indicators of an A deficiency.

Vitamin A also is key in fixing circadian rhythm. So many people deal with insomnia, daytime fatigue, and they have more energy in the evening. This happens a lot with adrenal issues, and it is a big sign that circadian rhythm is off.

One of the BIGGEST lies we have been told is that beta carotene is the same as vitamin A. While beta carotene is an important nutrient, it has to go through a process to be converted into retinol. In order to make this conversion we need a healthy gut, healthy liver and gallbladder (bile flow is the KEY), and certain enzymes and nutrients (like zinc). From this study, “β-Carotene is absorbed from the intestine and is converted into vitamin A only in the presence of bile acids.”  Using something like Cod liver oil that has retinol helps you get the REAL vitamin A that you need, because we cannot depend on the beta carotene converting.


Cod Liver Oil has REAL Vitamin D

There is a lot of hype about vitamin D. So many people push high doses of it without understanding that we are we are meant to get D from the sun and in small amounts from food. Period. You CANNOT bottle sunshine and I find it preposterous that this supplementing fad has continued for so long. Cod liver oil is one of the oldest and most effective ways to supplement vitamin D. We need a lot more vitamin A than vitamin D, and cod liver oil provides this balance.

We also need healthy livers to utilize both A and D. This is why liver support is so crucial for healing! We need these fat soluble vitamins, but we cannot use them properly with sluggish livers.

Vitamin D is still a truly crucial hormone. Vitamin D deficiency signs include chronic infections (including susceptibility for getting the flu), muscle weakness, diabetes, kidney disease, asthma, tooth decay, cancer, depression, and anxiety. This is why Cod liver oil can be great for those that need vitamin D, but don’t want to risk using high dose supplements (which I don’t recommend anyway- you can read why here!)


My Favorite Cod Liver Oils


dropi cod liver oil at perfect







Recently (4/2023), it’s been hard to get NutraPro, so I’ve been looking at the other CLOs that Perfect offers. Dropi is a great brand that I’ve heard good things about for the last few years. So while NutraPro is unavailable (not sure if or when it’ll be back in stock), I’ve been recommending Dropi more.

There are quite a few options on Perfect for Dropi- capsules, plain liquid, or flavored liquids. You can see all the options here.

Dropi is truly of amazing quality, and to be honest we’re enjoying the taste more than we did the Nutrapro (we got the Mandarin flavor!).

  • No heat, no fermentation, no solvents
  • Pure
  • Raw
  • Cold-pressed fresh with each day’s catch
  • Available in liquid and capsules

  • Fished sustainably and responsibly
  • Gluten-free and Non-GMO
  • For the liquid, one bottle will give you 34 servings of 1 teaspoon.

  • Made from wild Norwegian Arctic cod from the purest sea water.
  • Processed within 24 hours in effective and gentle manner.
  • Separated from fresh cod fish livers using cold pressed purifying technologies without the use of chemicals.

  1. Completely confused about supplementing Vitamin D. Cod liver oil – many people say has too much Vit A in it. And is the Vitamin D added to it, or naturally occurring? Then there are Vitamin D supplements with K2 or 3 added? I am constantly low in Vitamin D from Oct to Apr and need to supplement. It seems like people promoting and explaining using Vitamins sound like they are persuaded they are giving correct info, but people do contradict each other. Someone has to be wrong so how do you decide who?

  2. I go with what nutritional science tells us. We don’t consume large amounts of vitamin D naturally, ever. we need vitamin A to utilize D correctly and we need a healthy gut and liver and healthy kidneys to utilize vitamin D correctly. I do have a vitamin D article too that explains the best way to approach a deficiency, and you need to be looking at 2 levels to truly determine what’s going on-

  3. Hi Kristin! I’m so glad you are back on FB – I just found this out the other day – I was one of your first followers when you started years ago. My son is in college now and has been taking Vit D pills but ran out and is asking for more. I am not sure what to order. He’s in a dorm room without a kitchen, so I don’t think liquid is going to be a good option for him right now, and he’s super picky, so he’ll probably not take it b/c of the taste. I’m sure he won’t do the cream, only b/c it smells like fish – and well, he’s in college, the last thing he wants is to smell like fish. Is there good Cod Liver in a pill/capsule form? I was looking on Amazon and saw Fish Egg supplements from Ancestral Supplements and other than the cost, they look like they could be winner – any experience with them or this company? Thanks a million!

  4. Hey Christy! It’s so good to see your name, I’m glad you found me again 🙂

    So I believe Dropi is the best option for capsules- Rosita’s has them but they are so much more expensive than other brands. Capsules just don’t have AS much of the nutrients per serving as the straight liquid dose. I have seen the Ancestral brand, and originally was going to start recommending them but the price is a huge deterrent (plus, one of our group members contacted them recently and they were lied to when asked if some of their items have synthetics- some do, and they say they don’t).

  5. Hi, I’ve recently implemented clo and vit d/a cream. Each time I get diarrhea and dizzy spells. It seems like my electrolytes go out of balance. I’m not sure how to mitigate this or why it does it. Maybe lower and slower doses?

  6. If the vitamin D/a cream is synthetic at all it can be lowering your potassium levels, which can cause those symptoms you mentioned.

  7. Hi Kristen, thank you for your fast response. I’m using the ‘now solutions’ for vit d/a and nordic naturals for clo. Both appear to be doing the same. I held off for a few days with both products and used a pea sized drop of the cream. The following day the same symptoms appeared. Much less aggressive but there and not much fun.

  8. Hey Jayne! I’ve not heard of that Now one- it sounds like it could have been a bit too much at once. We need a healthy liver to be able to utilize vitamins A and D, so some do need to really work on that first before adding things like CLO in.

  9. Okay, thank you so much Kristen. I must need to do more work on my liver. I’m using castor oil packs, digestive bitters, dandelion coffee and nettle infusions. Adding in the clo and cream was probably too much too soon for my body. I appreciate you getting back to me.

  10. Thank you! 🙂

    Yes, you might just need some more time to truly heal your liver before adding them in then. I hope you find the best balance for you!

  11. Hi Kristin, what about PUFA’s? I worry about the PUFA’s when it comes to fish oils. Also, what about eating cod liver from the can, I enjoy this very much. If one goes for the can instead, how often should we have the can? What are your thoughts on this? Thank you so much.

  12. (I got your other comment and edited your name!)

    I know Ray Peat is one that has info on the PUFAs and I’ve seen people bring up the concerns. I think he’s a bit out there with some ideas, and I personally haven’t seen issues with CLO long term. I don’t recommend other fish oils though. If you’re in the Sassy Holistics Mineral Mavens FB group, you can search for “PUFA” and we have a good thread on this from last month. I’m sure eating them from the can would be good though!

  13. Thank you so much Kristin!!! I will check it out!!! Appreciate your feedback!! BTW, thank you for the edit. :o)
