With the continuous promotion of the importance of health in society, more and more people are paying attention to their physical and mental health, so various health products have received widespread attention. I believe everyone has heard of fish oil, but what exactly is fish oil? And what is the difference between fish oil and cod liver oil? This is the topic of this article.

Source:

* Fish oil is derived from the bodies of large marine fish and is mainly composed of Omega-3 fatty acids (including DHA and EPA), which are polyunsaturated fatty acids. Fish oil is a byproduct of fish meal processing, obtained from fish and their waste through steaming, pressing, and separation.
* Cod liver oil is a type of fat oil extracted from codfish and non-toxic marine fish. At around zero degrees, some solid fats will be removed. Then, refined high-concentration cod liver oil, vitamin A, vitamin D3, or vegetable oil are used to adjust the concentration. Finally, a suitable stabilizer is added to produce the final product.

Target Audience:
* Fish oil is suitable for a wide range of people:
1. For healthy individuals, taking fish oil can benefit the body, especially when the consumption of fish is insufficient. Consuming fish oil in moderation can help supplement fatty acids and prevent nutrient deficiencies.
2. To support normal growth and development, Fish oil can help supplement essential fatty acids and other nutrients for special populations, such as pregnant women, infants, and children.
3. For patients with certain diseases such as coronary heart disease, visual impairment, arthritis, etc., taking fish oil is beneficial for controlling the condition.
* Fish liver oil is suitable for people who lack vitamins A and D and those with poor physical condition and low immunity. Compared to fish oil, its target population is relatively narrow.

Safety:
* Fish oil is relatively safe and can be used by most people.
* Cod liver oil should be taken under the guidance of a doctor, especially for those who need vitamins A and D, as excessive use may lead to toxicity.

Side effects:
* Long-term intake of fish oil may pose the following risks: increased risk of bleeding; increased gastrointestinal motility leading to diarrhea; excessive intake may lead to abnormal blood sugar levels, and there is also a possibility of allergies and exacerbation of diseases.
* Overconsumption of cod liver oil may have the following hazards: Cod liver oil is rich in vitamin A and vitamin D. Excessive intake can lead to toxicity or hypercalcemia. In addition, cod liver oil may cause gastrointestinal discomfort.

Price:
Due to the different ingredients, extraction methods, and effects of cod liver oil and fish oil, there is a significant price difference between the two. Fish oil, also known as 'brain gold,' is relatively expensive, while cod liver oil is much cheaper. Therefore, when purchasing products, it is important to choose the right product based on your actual needs.

How to eat:
* Fish oil is oil extracted from fatty fish, better absorbed when consumed with food containing fat. Therefore, it is recommended to take fish oil with meals or after meals, as food can help increase the absorption of fish oil in the body. For those taking medication, it is advisable to consult a pharmacist before consumption to avoid any potential interactions between fish oil and the medication, which may affect their respective absorption.
* It is best to take cod liver oil after meals. You can add cod liver oil to beverages or food to avoid its strong taste. Cod liver oil can also be taken in capsules, making it easier to control the dosage and avoid the strong taste and odor. Regardless of the method, it is recommended to consult a professional first to ensure safety.

Function:
* Fish oil can maintain heart health, treat mental disorders, protect eye health, alleviate symptoms of rheumatoid arthritis, maintain skin health, improve symptoms of depression, relieve vascular tension, and regulate blood pressure. In addition, fish oil nourishes and enhances brain health, promoting the full development of brain cells and preventing intellectual decline, memory loss, and dementia. Fish oil can also improve bone health, improve asthma symptoms, and reduce the risk of allergies.
* Cod liver oil contains vitamin A, which can maintain normal vision, promote growth and development, and maintain epithelial tissue cells. Vitamin D can promote the absorption of calcium in the body. The unsaturated fatty acid glycerol in cod liver oil can promote fat metabolism and clear cholesterol and lipids in blood vessels, thereby reducing blood lipids and protecting the cardiovascular system.
The above is an introduction to fish oil and cod liver oil. I believe that after reading my article, everyone will have a better understanding of the efficacy, ingredients, and differences between the two and be able to find products that are more suitable for themselves.
