  • vitamin A: 90 % Rd
  • vitamin D: 113% Rd

Cod liver oil is nutritious. With one teaspoon, you will get about 90% of your daily vitamin A needs and 113% of your daily vitamin D needs.

Vitamin A has many roles in the body, including maintaining the health of the eyes, brain, and skin function.

Cod liver oil is one of the best dietary sources of vitamin D, which has an important role in maintaining bone health by regulating calcium absorption.

2. taking cod liver oil reduce inflammation

cod liver oil capsules It has a role in the natural process that helps the body fight inflammation and heals injuries.

Unfortunately, sometimes, inflammation can persist at a low level for long periods of time, which is known as chronic inflammation, which is harmful and can increase the risk of high blood pressure and many diseases, such as heart disease.

The omega-3 fatty acids found in cod liver oil capsules can reduce chronic inflammation by inhibiting proteins that promote it.

Cod liver oil also contains vitamins A and D, which are powerful antioxidants. It can reduce inflammation by binding and neutralizing harmful free radicals.

Interestingly, studies also show that people who are deficient in vitamins A and D are more likely to develop chronic inflammation.

3. cod liver oil capsules It may improve bone health

It is extremely important to maintain healthy bones as your age. This is because you start to lose bone mass after age 30.

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

Getting enough vitamin D from foods and supplements such as cod liver oil is especially important for people who live far from the equator because their skin does not get enough sunlight to synthesize vitamin D for up to six months of the year.

4. cod liver oil dosage It can reduce joint pain and improve symptoms of rheumatoid arthritis.

(Rheumatoid arthritis is an autoimmune disease characterized by joint damage.)

There is currently no cure for rheumatoid arthritis, but studies suggest that cod liver oil capsules can reduce joint pain and improve rheumatoid arthritis symptoms such as stiffness and swelling of the joints.

In one study, 43 people took a 1-gram capsule of cod liver oil daily for three months. The researchers found that it reduces the symptoms of rheumatoid arthritis, such as morning stiffness, pain, and swelling.

In another study that involved 58 people, researchers investigated whether taking cod liver oil would reduce pain caused by rheumatoid arthritis enough to help patients reduce their use of anti-inflammatory medicines.

At the end of the study, 39% of people who comfortably took cod liver oil reduced their use of anti-inflammatory drugs by more than 30%.

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

5. taking cod liver oil May support eye health

Vision loss is a major health problem, affecting more than 285 million people worldwide.

There are many reasons why people lose their vision, but two of the main causes are glaucoma and age-related macular degeneration (AMD).

However, omega-3 fatty acids and vitamin A in cod liver oil have been shown to protect against eye diseases caused by inflammation.

Animal studies have found that omega-3 fatty acids reduce risk factors for glaucoma, such as eye pressure and nerve damage.

In another study of 666 people, researchers found that those who ate the most omega-3 fatty acids had a 17% lower risk of early AMD and 41% lower risk of late AMD.

Furthermore, diets rich in vitamin A may reduce the risk of glaucoma and AMD, compared to diets lower in vitamin A.

In one study of 3,502 people aged 55 and over, researchers found that people who took the most vitamin A had a significantly lower risk of glaucoma than those who took the least vitamin A.

Although vitamin A is good for eye health, high doses of it are not recommended, as it may cause vitamin A toxicity.

6. cod liver oil capsules may reduce the risk of heart disease

Heart disease is the leading cause of death worldwide, affecting over 17.5 million people annually.

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

Omega-3 has been shown to have many benefits for your heart, including:

  • Reduce triglycerides: 
the omega-3 fatty acids in cod liver oil may reduce blood triglycerides by 15-30%.

  • Lowering blood pressure: 

several studies have found that omega-3 fatty acids may lower blood pressure, especially in people with high blood pressure and high cholesterol.

  • Increase HDL cholesterol: 

the omega-3 fatty acids found in cod liver oil can raise good HDL cholesterol, which is associated with a lower risk of heart disease.

  • Prevent plaque formation: 

animal studies have found that cod liver oil may reduce the risk of plaque formation in arteries. Plaque buildup can narrow your arteries and lead to a heart attack or stroke.

While taking fish oil supplements such as cod liver oil may reduce risk factors for heart disease, there is little evidence that it can prevent heart disease or strokes.

Unfortunately, few studies have specifically examined the association between cod liver oil and heart disease, with many studies classifying cod liver oil as normal fish oil.

Thus, more specific research is needed on cod liver oil and heart disease risk factors to establish a clear link between the two.

7. cod liver oil may improve symptoms of anxiety and depression

Anxiety and depression are common diseases that together affect over 615 million people worldwide.

Interestingly, studies suggest that there may be a link between chronic inflammation, anxiety, and depression.

Several studies have found that the omega-3 fatty acids found in cod liver oil can reduce inflammation and reduce symptoms of anxiety and depression.

A large study involving 21,835 individuals found that people who regularly taking cod liver oil had fewer depressive symptoms or experienced anxiety on their own.

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

In an analysis of 26 studies that included 1,478 individuals, omega-3 supplementation was slightly more effective than placebo in reducing symptoms of depression and anxiety.

In addition, several studies have also found a link between increased levels of vitamin D in the blood and decreased symptoms of depression.

It is not yet clear how it reduces symptoms of depression, but some studies suggest that vitamin D can bind to receptors in the brain and stimulate the release of mood-enhancing hormones such as serotonin.

8. Take cod liver oil can help heal stomach and intestinal ulcers 

(Ulcers are slight breaks in the stomach's lining or intestines).

Its symptoms can cause nausea, upper abdominal pain, and discomfort, they are often caused by bacterial infections, smoking, excessive use of anti-inflammatory drugs, or too much acid in the stomach.

Animal studies show that cod liver oil can help treat ulcers, especially in the stomach and intestines.

In an animal study, researchers found that low and high doses of cod liver oil helped heal ulcers in both the stomach and intestines.

Another animal study found that cod liver oil inhibits genes associated with enteritis and reduces inflammation and ulceration in the intestine.

While the use of cod liver oil to help heal ulcers seems promising, more studies on humans are needed to make clear recommendations.
