Cod Liver Oil Benefits For Skin, Hair, And Health


Cod liver oil like regular fish oil, it is high in omega-3 fatty acids, which are linked to many health benefits, including reducing inflammation and lowering blood pressure.It also contains vitamins A and D, which provide many other health benefits.

Cod liver oil benefits

Here are 9 benefits of cod liver oil that have been proven and supported by science.

1. High content of Vitamins A and D

Although cod liver oil is a fish oil supplement, it is very different from regular fish oil. Regular fish oil is extracted from fatty fish tissue such as tuna, herring, anchovy and mackerel, while cod liver oil is extracted from cod livers.

The liver is rich in fat-soluble vitamins such as vitamins A and D, which give it an impressive nutritional profile.

In 5ml (One teaspoon) of cod liver oil provides the following:

Calories: 40
Fat: 4.5 grams
Omega-3 fatty acids: 890 mg
Monounsaturated fat: 2.1 grams
Saturated fat: 1 gram
Polyunsaturated fat: 1 gram
Vitamin A: 90% of the RDI (Recommended Daily Intake)
Vitamin D: 113% of the IDR
Cod liver oil is incredibly nutritious, with just one teaspoon you can provide 90% of your daily needs for vitamin A and 113% of your daily needs for vitamin D.

Vitamin A has many important actions in the body, including maintaining healthy eyes, functioning of the brain and skin care.

Cod liver oil is also one of the best dietary sources of vitamin D, which plays an important role in the maintenance of healthy bones by regulating the absorption of calcium.

2. It can reduce inflammation

Unfortunately, in some cases, inflammation may continue at a low level for long periods of time.

This is known as chronic inflammation, which is harmful and may increase the risk of high blood pressure and various diseases, such as heart disease.

The omega 3 fatty acids in cod liver oil can reduce chronic inflammation by suppressing the proteins that promote it. These include TNF-α, IL-1 and IL-6.

Interestingly, studies also show that people who are deficient in vitamins A and D are at increased risk of chronic inflammation.

3. It can improve bone health

It is very important to keep bones healthy as we get older. This is because we started to lose bone mass after 30 years. This can lead to fractures at later ages, especially in women after menopause.

Cod liver oil is an important source in the diet of vitamin D and can reduce bone loss related to age. That’s because it helps the body absorb calcium, which is a necessary mineral for strong bones, from the intestine.

In fact, studies show that when accompanied by a diet rich in calcium, taking a vitamin D supplement such as cod liver oil can reduce bone loss in adults and strengthen fragile bones in children.

4. Can Reduce Joint Pain and Improve the Symptoms of Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease that is characterized by damage to the joints. There is currently no cure for rheumatoid arthritis, but some studies suggest that cod liver oil can reduce joint pain and improve the symptoms of rheumatoid arthritis, such as joint stiffness and inflammation.


It is believed that omega-3 fatty acids in cod liver oil can help reduce inflammation in the joints and protect against damage.

5. Can improve eye health

The loss of vision is a huge health problem that affects more than 285 million people around the world. There are many reasons why people lose their vision, but two of the main causes are glaucoma and age-related macular degeneration (AMD).

Both diseases can result from chronic inflammation. However, it has been shown that omega-3 fatty acids and vitamin A in cod liver oil protect against eye diseases caused by inflammation.

In addition, diets high in vitamin A are more likely to reduce the risk of glaucoma and AMD, compared to lower diets in vitamin A. Although vitamin A is excellent for eye health, it is not recommended to take it in high doses, as it can cause vitamin A poisoning.

6. Can Reduce the Risk of Heart Disease

Studies have shown that people who regularly eat fish have a much lower risk of developing heart disease. This effect can be attributed to its content in omega-3 fatty acids.

It has been proven that Omega-3 oils have many benefits for your heart, including:

Reduction of triglycerides: Omega-3 fatty acids in cod liver oil can reduce blood triglycerides by 15 to 30%.
Decrease in blood pressure: Many studies have found that omega-3 fatty acids can lower blood pressure, especially in people with high blood pressure and high cholesterol.
Increased HDL cholesterol: Omega-3 fatty acids in cod liver oil can raise good HDL cholesterol, which is linked to a lower risk of heart disease.

Prevention of plaque formation: the buildup of plaque can narrow the arteries and cause a heart attack or stroke. While taking fish oil supplements such as cod liver oil can reduce the risk factors for heart disease, there is little evidence that it can prevent heart disease or stroke.

7. Can Improve Symptoms of Anxiety and Depression

Omega-3 fatty acids and vitamin D in cod liver oil may help reduce the symptoms of anxiety and depression, but more studies are needed.

Interestingly, studies suggest that there may be a link between chronic inflammation and anxiety and depression. Many studies have found that omega-3 fatty acids in cod liver oil can decrease inflammation and reduce the symptoms of anxiety and depression.

However, while omega-3 fatty acids help reduce symptoms of anxiety and depression, their overall effect seems small.

On the other hand, many studies have also found a link between increasing blood levels of vitamin D and reducing symptoms of depression.

Also, some studies suggest that vitamin D can bind to receptors in the brain and stimulate the release of hormones that improve mood like serotonin.

8. Can help cure stomach and intestinal ulcers

Cod liver oil may help treat ulcers in the stomach and intestine, but more studies in humans are needed before making recommendations. Ulcers are small breaks in the lining of the stomach or intestine. They can cause symptoms of nausea, pain in the upper abdomen and discomfort.

They are often caused by bacterial infections, smoking, excessive use of anti-inflammatory medications or too much acid in the stomach.

9. Easy to add to your diet

Cod liver oil is incredibly easy to add to your diet. It comes in many forms, but liquid forms and capsules are the most common.

There are no established guidelines for the intake of cod liver oil, so most recommendations are based on safe levels of intake of omega-3 fatty acids, and vitamins A and D.

A common dose is often 1 to 2 tablespoons, but taking up to one tablespoon per day is generally safe. Higher doses are not recommended, as they would result in excessive intake of vitamin A.

Although cod liver oil is very healthy, some people need to be cautious with the intake, since cod liver oil can act as an anticoagulant.
