Cod Liver Oil & Butter Oil Questions And Answers
















Order your cod liver oil and high vitamin butter oil here for local pick up. And here to have it shipped to your door.

What is the storage life of cod liver oil and butter oil?

Green Pasture does not provide an official shelf life span for their cod liver oil or butter oil, but I called them and was told verbally that their products should be good for 2 plus years – even at room temperature. If you plan to stock up and store it this long, please note that at room temperature, the flavor of the cod liver oil may become stronger over time because it is fermented and will continue to ferment at room temperature. Therefore, we recommend that you keep extra bottles in the fridge or freezer.

Do cod liver oil or butter oil need to be refrigerated?

No, they can both be refrigerated or stored at room temperature, even after opening. It’s a matter of personal preference. Just keep the bottle out of direct sunlight.

If you plan to keep your cod liver oil at room temperature, please note that its flavor may become stronger over time because it is fermented and will continue to ferment at room temperature. For this reason, we recommend that you refrigerate the bottle if it will take you longer than 3 or 4 months to use up.

Some people prefer the texture of cod liver oil or butter oil when it is has been refrigerated, and others like it better at room temperature.


Can cod liver oil and butter oil be frozen?

Yes, they can both be frozen.


What is the difference between the liquid fermented cod liver oil and the butter oil/cod liver oil blend?

Dr. Weston Price found that when “[a high vitamin] butter oil is mixed in equal parts with a very high-vitamin cod liver oil, it produces a product that is more efficient than either alone.” In other words, he got better results when he used the butter oil together with the cod liver oil. People healed remarkably faster when both were used together.

Technical Differences:  The liquid fermented cod liver oil is just cod liver oil. The cod liver oil/butter oil blend is two-thirds cod liver oil and one-third high vitamin butter oil, blended together for convenience.

Taste/Texture Differences:  I’ll compare the cinnamon tingle fermented cod liver oil (FCLO)/butter oil (BO) blend and the cinnamon tingle FCLO liquid.

Cinnamon Tingle FCLO Liquid:  sweet cinnamon flavor nicely masks the fishy taste, at least as liquidy as maple syrup at room temperature, slightly thicker when refrigerated, cinnamon taste is a little stronger than in the FCLO/BO blend

Cinnamon Tingle FCLO/BO blend: sweet buttery cinnamon taste, fishy taste masked just as well as cinnamon tingle liquid, thick gel when refrigerated, semi-solid at room temperature




How many servings are in a bottle of cod liver oil? Butter oil? 

Butter Oil: 96 half teaspoon servings

Cod Liver Oil: 118 2mL servings or 96 half teaspoon servings

Cod Liver Oil/Butter Oil Blend: There are 96 half teaspoon servings. However, Dr. Weston Price recommended taking a half teaspoon each of cod liver oil and butter oil at the same time. Therefore, you may want to take a full teaspoon of the blended cod liver oil and butter oil.

Do I need to take high vitamin butter oil along with the cod liver oil?

If it is within your budget, yes. Here is an excerpt from the Weston A. Price Foundation that illustrates how much more effective cod liver oil is when taken with high vitamin butter oil.

 Dr. Price was often called to the bedsides of dying individuals, when last rites were being administered. He brought with him two things—a bottle of cod liver oil and a bottle of high vitamin butter oil from cows eating growing grass. He put drops of both under the tongue of the patient—and more often than not the patient revived. He was puzzled by the fact that cod liver oil alone and butter oil alone seldom revived the dying patient—but the two together worked like magic. (source)


Why high vitamin butter oil? Can I use regular butter instead?

It depends. Is your butter from grass fed animals?

The high vitamin butter oil from Green Pasture (and also the ghee we offer from Pure Indian Foods) is made from the milk of cows grazing on the rapidly growing green grass during spring and fall only. This “butter that has the grassy flavor and the deep yellow to orange color… is usually several times as high in fat-soluble activators including vitamins A and D as butter produced from stall fed cattle or cattle on poorer pasturage.” (Nutrition and Physical Degeneration, Weston A. Price) It is also several times higher in vitam K2, whereas butter produced from cows eating grains and confined in stalls may have a little K2, but not much.

So if you can get your hands on a good quality, grass-fed butter, you don’t need the high vitamin butter oil.

Another thing that can substitute for high vitamin butter oil is raw, grass-fed cheese.

Incidentally, vitamin K2 is also associated with a reduced risk of coronary heart disease and the prevention of arterial calcification.



Will capsules give me the same benefit as the liquid? Or does the liquid need to come into contact with my teeth?

Capsules will give you the exact same benefit as the liquid, and no, the liquid doesn’t need to come in contact with your teeth. It nourishes from within the body.



How Many Capsules Should I Take?

10 capsules equal 1 teaspoon of liquid cod liver oil (see the section below on how much to take based on age)



I experience fishy burps when I take cod liver oil capsules.

Try storing your capsules in the freezer. The cod liver oil will stay frozen for a little while after you swallow and thaw once it has safely arrived in your stomach. Problem solved!



How much cod liver oil should you take?

There are two basic kinds of cod liver oil; high vitamin cod liver oil and regular cod liver oil. These recommended doses are for the high vitamin cod liver oil, which is the kind we offer. (Twice as much regular cod liver oil is needed to equal the benefits of high vitamin cod liver oil.)

Children age 3 months to 12 years: 1/2 teaspoon or 2.5 mL (5 capsules)

Children over 12 years and adults: 1 teaspoon or 5 mL (10 capsules)

Pregnant and nursing women: 2 teaspoons or 20 capsules


Please note that the fermented cod liver oil contains many co-factors that may enhance the body’s uptake and usage of vitamins A and D, and many people use half the recommended amounts and report results that are the same as if they had used the full amounts.

Is there any research about regenerating adult tooth problems?

Yes, it’s absolutely possible! Here is one story of a woman who healed six cavities in her own mouth using cod liver oil and butter oil. There is also a complete book on the subject, Cure Tooth Decay by Ramiel Nagel. The book is worth its weight in gold fillings.




How much high vitamin butter oil should you take?

Take the same amount of butter oil as cod liver oil. So if you are taking 1/2 teaspoon of cod liver oil, take 1/2 teaspoon of butter oil at the same time.



How To Take Fermented Cod Liver Oil

We think Green Pasture has done an excellent job masking the fishy taste in their cod liver oils, especially the cinnamon flavors. The kids in this video are tasting the cinnamon tingle liquid – their first time ever to taste cod liver oil. They can show you just how easy it is.

But if you’re still scared, here are some practical suggestions to get it down. And if all else fails, use the capsules.

  • mixed into yogurt
  • mixed into applesauce
  • mixed into juice
  • follow with a chaser like milk, juice, tea, or a bite of a muffin or toast spread with high vitamin butter oil
  • mixed with honey
  • mixed with mashed banana (especially for little ones)



My cod liver oil appears cloudy. Is this normal?

Cod liver oil may become cloudy or appear crystalized when it’s been kept in the fridge. This is normal and not an indication that it has gone bad.




The date stamped on the side of my bottle of fermented cod liver oil or butter oil has passed.

That date is the manufacture date, the date the cod liver oil (or butter oil) was made. It is not an expiration date.
