In a study done on women in 2009, researchers had concluded that consumption of omega-3 fatty acids in good amount lowers symptoms of depression.

They also found that lower content of omega-3 acids in blood serum has higher depression symptoms.

However, more studies are yet to be done to justify that consumption of cod liver oil helps reduce symptoms of depression.

According to Andrew L. Stoll, MD, a neuroscientist at Harvard Medical School, who has done significant researches on omega-3s on various diseases, found that omega-3s are capable of treating depression.

10. A great pregnancy and fertility food

The deficiency of vitamin D in women lowers their pregnancy rates and studies suggest that around 50% of women are deficient in vitamin D.

12. Helps to control your blood pressure

High blood pressure or hypertension has no visible symptoms and that makes it very dangerous.

And if it is not treated, it can harm vital organs of the body including kidney, eyes, heart as well as blood vessels that may result stroke, heart failure, loss of eyesight and premature failure of kidneys.

Omega-3 fatty acids available in CLO are found to be beneficial in reducing systolic blood pressure.

13. Improves your heart health

Consumption of essential fatty acids (Omega-3s) improves heart health that prevents the risk of heart failure and sudden death.

It is also helpful to keep your heart healthy even after a heart attack or surgery because of its amazing properties of altering arteries lining in such a way to promote faster healing after the damage.

14. Improves your brain function

Essential fatty acids are helpful to maintain proper functioning of our brain, and also help in the fast recovery of any damage caused due to external or internal injuries.

To be noted that our brain is made of sixty percent of fat, and in that DHA (Docosahexaenoic acid) alone accounts for 15 to 20 %.

Therefore, it is clear that high dosages of omega-3s fatty acids have a good impact on the normal brain functions and faster healing due to any damage.

15. Controls your blood glucose levels

Normally, a person with increased blood glucose levels has low HDL (high-density lipoprotein) and increased triglycerides levels.

However, omega-3 fatty acids in cod liver oil have a good impact in controlling triglycerides and maintaining a healthy HDL level.

16. A good source of Vitamin D for children

Daily recommended intake of vitamin D for children aged up to 12 months is 400 IU or 10 mcg, and for age 1 to 13 years, it is 600 IU or 15 mcg.

And the best source of getting vitamin D is our skin through sunlight. However, children are not supposed to be in sunlight due to their sensitive skin for a long time due to burns caused by it.

Therefore, it is recommended to get vitamin D drops to feed required vitamin D in the body. And this can be supplemented by cod liver oil.

17. Immunity Booster

With a good concentration of vitamin A, it helps to fight infections and makes our immune system stronger.

Are there any cod liver oil side effects?

Till now, we have just discussed one side of the coin, and that is the positive aspects of cod liver oil.

However, taking it in a limited amount is not concerned with side effects, but high dosages may cause heartburn, nose bleeding and nausea.

And it is due to the fact that it is rich in vitamin A and vitamin D.

High dosage of vitamin A (also referred as vitamin A toxicity or hypervitaminosis A) can lead to abdominal pain, drowsiness, pressure on brain, skin irritation etc., and chronic intakes of vitamin A may even lead to death.

Therefore, to reap the benefits of cod liver oil, keep your vitamin A, D intakes in required amount. Therefore, if you are taking cod liver oil supplements then read the labels to get the better idea of vitamin contents or consult your pharmacist or doctor.

Which one is better, fermented cod liver oil or normal cod liver oil?

Fermentation is a type of food processing with the main purpose of eliminating anti-nutrients, getting the food into good flavors, and preserving essential vitamins and minerals.

Fermented cod liver oil is obtained by the fermentation of livers of cod fish.

And after fermentation, the essential nutrients (omega-3 fatty acids, water soluble vitamins) are preserved in good proportion, also it smells good.

Additionally, fermentation has added advantages over other ways of food processing including heating and synthetic food processing because it keeps the molecular structure intact even after processing. 

​Therefore, the benefits of fermented cod liver oil supersede the benefits of standard cod liver oil.  

Some of the frequently asked questions about cod liver oil:

1. Should pregnant or breastfeeding women avoid it?

Definitely, a breastfeeding woman needs the recommended daily intake of vitamins to bring up a healthy child.

However, our daily required vitamin A is fulfilled by a variety of foods and vegetables we eat every day, and vitamin A deficiency is rare in the United States and other developed nations.

But, it is common in third world countries (developing countries) where many people don't have enough eatables to get their daily required vitamins especially breastfeeding and pregnant women.

However, increased numbers of minerals and vitamins are required for a breastfeeding woman to provide proper milk supply to the infant.

Therefore, a breastfeeding woman needs multivitamin supplements along with fruits and vegetables to cope with the increased demand of nutrients.

Also omega-3s (DHA&EPA or referred as marine omega-3s or n-3 fat) which are found in cod liver oil are good for fetal neurodevelopment and timing of gestation, and they are not produced in our body but are received through diets or supplements.

Therefore, if you are not getting enough omega-3s from your diet, taking them as supplements is a good idea.

Cod liver oil also provides enough vitamin D, and can fulfil the deficiency of it in breastfeeding and pregnant women.

2. Is it effective to treat osteoporosis?

In Osteoporosis, the bones become porous and fragile that results to loss of bone strength.

However, there is a widespread misconception that calcium and vitamin D deficiency is the main cause of weak bones, but it is not true, a healthy diet which is rich in all types of minerals and vitamins keeps the bones rigid and provide them strength they need.

Also, exposure to sunlight provides us approx. 90% of our required vitamin D and rest of the amount can be absorbed by our daily diet.

Therefore, if we say that cod liver oil alone helps in relieving from osteoporosis it is not correct, however, it is a good source and can provide you enough vitamin D if you are a vitamin D deficient (a 100 gram serving of CLO provides you 210 mcg of vitamin D).

Conclusion:

Really Cod liver oil is a good source of omega-3s, vitamin D, and vitamin A and helps to fight with many severe medical conditions.

However, it is necessary to see the labels on supplements before using and consult your doctor before taking any supplement.
