What is fish oil and what are its benefits?

Fish oil is a type of fatty oil obtained from the fats and tissues of various fish. In appearance, fish oil appears to be liquid, in pale yellow color. It is insoluble in water, but quite soluble in acetone, heptane and anhydrous ethanol. Fish oil can be used to make supplements, cosmetics and even paint.

Largely mistaken to be the same as omega 3, fish oil is actually different in terms of components and structure. While omega 3 serves as a polyunsaturated fatty acid that comes in DHA (docosahexaenoic acid), ALA (alpha linolenic acid) and EPA (eicosapentaenoic acid) forms, fish oil is oil that only contains the DHA and EPA forms of omega 3. The DHA is instrumental in making fish oil beneficial to the growth and functional development of the brain. On the other hand, EPA makes fish oil naturally anti-inflammatory, in addition to its effects on protein synthesis.

By eating fish and microalgae that contains omega 3 fatty acids, fish can produce oil in its tissues that benefit human beings. In turn, humans get their regular intake of fish oil in supplements and food that make up omega 3, an important component of a healthy diet.

There are several uses for fish oil, from its health benefits to securing the condition of life in the city.

What is fish oil good for?

For the heart

In order to prevent heart disease, it is important to keep the triglycerides at a certain level. Fish oil can be used to reduce the triglycerides level by 50%. With increased physical activity and a healthy diet, the risk of developing heart disease and stroke can be restricted. It may also be wise to limit fish oil intake to a minimum as excessive intake may also be harmful to the heart.

For the brain

With significant amounts of DHA that contributes to the wellness of the brain, those who use fish oil have improved cognitive functioning. A good intake of fish oil may help to keep the brain healthy and reduce the risk of memory loss. Food and supplements with fish oil can also help to prevent Alzheimer’s disease, attention deficit-hyperactivity disorder (ADHD), psychosis and even depression.

For the kidney

Fish oil is known to prevent kidney diseases. However, for those who are currently on dialysis, fish oil can help to decrease chronic inflammation, a common problem for patients under treatment. Caution and consultation with a nephrologist is strictly recommended, as fish oil supplements may interfere with current medications.


As a natural anti-inflammatory supplement, fish oil can help those with chronic inflammatory diseases. It can also treat gastrointestinal disorders, short bowel syndrome, Celiac disease and inflammatory bowel disease (IBD). Patients with Crohn’s disease may find fish oil supplements effective despite the inability to absorb other vitamins and essential supplements.

Eyes and skin

Fish oil is used to prevent glaucoma, dry eyes and age-related macular degeneration or AMD. According to studies, those who include fish oil in their diet tend to reduce the risk of developing AMD. On the other hand, fish oil can also be used to make the skin vibrant and young-looking. It can treat acne, dry skin, eczema, skin redness, lesions, rashes and itching. Psoriasis can also be treated because of the arachidonic acid produced by EPA in fish oil, resulting in the restriction of the growth of inflammatory agents.

Weight loss

Feeling frustrated with ineffective weight loss programs? The combination of fish oil supplements and exercises result in a powerful training program. Since DHA has an insulin-sensitizing ability and EPA has anti-inflammatory benefits, significant amounts of both components create an improved weight loss complement to a good exercise program.

Protection from air pollution

Pollution has been a problem in many cities because it has negative effects on a person’s cardiovascular health.

Fish oil supplements can protect the body from adverse cardiac and lipid effects caused by pollution.

Bone health and lean muscles

To prevent osteoporosis, calcium and vitamin D is not enough. The DHA in fish oil is essential to the health and density of the bones. Besides good bones, fish oil can also help preserve lean muscles. A diet with fish oil prevents muscle loss, even for those who undergo chemotherapy.


The shortening of the telomere, a DNA at the end of a chromosome, can prevent stem cell functioning and cellular regeneration, both key to hampering the signs of aging. Fortunately, studies have found that fish oil helps to prevent the shortening of the telomere. Apparently, the higher levels of fish oil in the diet, the longer the telomeres.

Various diseases and illnesses

Conditions and diseases such as asthma, lupus, movement disorders, dyslexia and developmental coordination disorders can be treated with fish oil supplements. Women who experience menstrual cramps and breast pain or would like to prevent high blood pressure, miscarriage and early delivery during pregnancy can also benefit from fish oil.
