  • Sharebar

The decision to start using cod liver oil supplements is a great step to help with your overall health, but it can be very confusing to find a good brand of supplements to purchase. There are a lot of brands and options available at the grocery store, drug store, health food store and even online. Even though they all may seem similar in quality, there are actually big differences in the production methods and the nutritional benefits that can be gained by using the various types of oil. This article is going to help you understand why the production methods matter, and which type of oil is the best brand to use in order to gain the optimal amount of nutrition from the supplement.

Methods of Cod Liver Oil Production

Traditionally, this oil was produced by allowing the cod livers to ferment in a large wooden barrel with a little bit of sea water. European fisherman began producing the cod liver oil with this natural fermentation process, and the fermentation was used for many years until the manufacturing age discovered how to produce the oil without fermentation.

Once it was discovered that cod liver oil cod be extracted using methods of high heat and refining the oil, most companies began selling these refined versions of the oil because it was much faster and cheaper to produce. All oils that have gone through the refining process have been stripped of some of the naturally occurring nutrients such as vitamin A and vitamin D. Because these natural nutrients are removed, the companies compensate by adding in synthetic vitamins so that they can list the vitamins on the nutritional label.

This modern method of production is sub-par to the fermentation process, and it produces a lower quality product as a result. If you want the full benefits of cod liver oil, then it is essential that you are only using a brand that specifically states that it is fermented.

Nordic Naturals Brand Cod Liver Oil

Nordic Naturals is one popular brand of cod liver oil, and many people purchase this oil because of the fact that they don’t add any synthetic vitamins. Even though there are no synthetic vitamins added in, the truth is that this oil still goes through a process that removes many of the nutrients. Don’t be fooled by the fact that this brand is called high quality, because the production methods do not preserve all of the nutritional benefits that may be available. Natural vitamins are added back in to replace the vitamin A and D that was removed from the oil, but it is still not as good as the real thing.

Green Pasture Cod Liver Oil

In comparison with the high-heat production methods that are used by the majority of the cod liver oil brands out there, Green Pasture has a proprietary process which involves fermentation and cold extraction in order to maintain the nutritional benefits in the natural oil. This fermentation process results in such a high nutrient density, that the oil is always better in vitamin A and D levels compared to other types of cod liver oil.

Another benefit to the fermentation process used by Green Pastures is the fact that the nutrients have better absorption rates compared with synthetic vitamins, which means that they are easier to assimilate within the body.

Vitamin A and D Levels

When comparing the levels of vitamin A and vitamin D in Nordic Naturals with Green Pasture, you will see that Green Pasture out-performs with these nutrients. For example:

  • 1 dose of Arctic Cod Liver Oil from Nordic Naturals provides between 9-30% of the daily value of vitamin A and 0-5% of the daily value of vitamin D for adults.
  • 1 dose of Green Pastures Fermented Cod Liver Oil Plain Liquid provides 75% of the daily value of vitamin A and 190% of the daily value of vitamin D for adults.

Green Pastures is Best

Because of the natural production methods and the high levels of nutrition, Green Pastures cod liver oil is the best choice to buy. Other benefits to using cod liver oil produced with fermentation can’t be quantified, because of the fact that there are thousands of other micro-nutrients that are available in the oil… some of those micro-nutrients haven’t even been identified yet.

The fermentation process of cod liver oil is the best way to preserve the natural health benefits that are available, because all of the nutrients need to be consumed together in their naturally occurring form. Other methods of cod liver oil extraction do not preserve this balance of nutrition, and result in a lower quality oil.

Green Pastures fermented cod liver oil can be purchased in a liquid form or in gel capsules, and both methods of supplementation provide high quality nutrition. Each person can decide on their preferred method to consume the oil, whether they would rather swallow a capsule or take it in liquid form.
