The Best Cod Liver Oil for Health

The best cod liver oil supplement should contain significant quantities of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These two types of omega-3 fatty acids support brain health, heart health, and overall anti-inflammatory effects in the body. Additionally, it should contain high levels of vitamins A and D, which are crucial for maintaining good vision, immune system function, bone health, and proper cellular growth.

Why Should I Take Cod Liver Oil?

Cod liver oil contains many health benefits and covers majority of your RDA (Recommended Daily Allowances) for Vitamin A, Vitamin D, and omega-3 fatty acids. 1 serving of cod liver covers 90% of your RDA for Vitamin A, 113% of your RDA for Vitamin D, and 800-1000 mg of omega-3 from EPA and DHA.

The Importance of Vitamin D in Your Diet

Vitamin D is a fat-soluble vitamin that is crucial to staying healthy and is important for bone health. Having vitamin D deficiency has been shown to compromise the immune system, cause issues with sleep, affect your digestion negatively, and more.

Low levels of vitamin D are linked to an increased risk of developing dementia and Alzheimer’s disease.

“results confirm that vitamin D deficiency is associated with a substantially increased risk of all-cause dementia and Alzheimer disease. This adds to the ongoing debate about the role of vitamin D in nonskeletal conditions”.

Vitamin D and the risk of dementia and Alzheimer disease. Neurology. 2014 Sep 2;83(10):920-8. doi: 10.1212/WNL.0000000000000755. Epub 2014 Aug 6. PMID: 25098535; PMCID: PMC4153851.

Vitamin D deficiency is linked to an increase in depression.

“low vitamin D concentration is associated with depression”

Getting enough vitamin D is essential and supplementing with cod liver oil accomplishes this need.

Vitamin A and Its Benefits

Cod Liver Oil vs. Fish Oil

Fish oil and cod liver oil are both dietary supplements that come from fish but have differences in their nutrient content and health benefits.

Cod liver oil contains higher levels of Vitamin A and D compared to Fish Oil and the amounts are perfectly balanced. However, fish oil has higher amounts of omega-3 fatty acids.

Cod Liver Oil Liquid Vs. Capsule

Both pill and liquid form of cod liver oil have their advantages and disadvantages. The choice between the two forms may depend on factors such as absorption rate, taste, convenience, and dosage.

Cons

If you have difficulty swallowing pills, the obvious choice is the liquid form.

If you prefer a more convenient and portable option, then cod liver oil in pill form may be the better choice. They are easy to take on the go and offer a tasteless and odorless option. Pills are also easier to measure, which can help ensure that you are getting the correct dosage.

If you prefer a more natural form of cod liver oil, then the liquid form is the better option. Since the liquid form is typically less processed, it may contain more nutrients (such as vitamins A and D). Additionally, some people find that liquid cod liver oil is easier to absorb and is faster-acting than pills.

Overall, the choice between the pill and liquid form will depend on your individual preferences, needs, and lifestyle.
