Omega 3 acids helps Fight diseases as well COVID 19


Omega-3 fatty acidsTrusted Source are fats commonly present in plants and marine life. 

Two types are plentiful in oily fish: eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Alpha-linoleic acid (ALA), meanwhile, mainly occursTrusted Source in plant-based foods, such as flaxseed.

Omega-3 is present throughout the body, especially in the brain, retina, and sperm cells. The body cannot produce omega-3 on its own, however, so people need to obtain it from dietary sources.

Potential health benefits

Scientists have linked omega-3 to a number of health conditions. However, it is not always clear whether or not taking additional omega-3 can offer benefits.

The following sections outline some of these conditions and some other health benefits that omega-3 may provide.


In 2020, survey data suggested that females who take probiotics, vitamin D, fish oil supplements, or a combination of these may have a slightly lower risk of developing COVID-19. 

However, this investigation has not yet undergone peer review, and the findings are far from conclusive. 

In fact, experts have warned against using supplements in an attempt to prevent infection with the virus.

Multiple sclerosis

Some people with multiple sclerosis (MS)take omega-3 because it may have protective effects on the brain and the nervous system. 

However, at least one studyTrusted Source has concluded that omega-3 supplements do not reduce disease activity with MS.

Prostate cancer

Some researchTrusted Source has suggested that eating a diet rich in omega-3 may help prevent prostate cancer. However, a 2013 studyTrusted Sourcesuggested that a high fish oil intake may actually increase the risk of high grade prostate cancer.

The precise link between omega-3 and different types of cancer remains unclearTrusted Source, but a number of studies have found no evidence to suggest that omega-3 either increases or reduces the risk of various types of cancer.

Postpartum depression

People with low levels of omega-3 during pregnancy and while breastfeeding may be more susceptible to postpartum depression.

The authors of a 2018 reviewTrusted Source concluded that taking fish oil supplements around this time may help reduce the risk of depression. 

However, people should avoidTrusted Source eating fish that may be high in mercury, such as shark and king mackerel, during pregnancy. Some good alternative choices include canned light tuna, salmon, pollock, and catfish. 

Memory and other mental health benefits

In addition to postpartum depression, some studiesTrusted Source suggest that EPA and DHA could help treat various neuropsychiatric conditions. These include:

Some studiesTrusted Source have suggested that omega-3 supplementation may help prevent cognitive decline, especially in older adults. However, their results are not conclusive, according to one 2019 reviewTrusted Source.

More investigations are necessary to confirm these benefits.

Heart and cardiovascular benefits

Omega-3 fatty acids in fish oils may help prevent heart disease and stroke, according to the AHATrusted Source.

Specifically, omega-3 may help manage:

2013 study found that people who took fish oil supplements for longer than 1 month had better cardiovascular function during mentally stressful tests.

In 2012, researchers notedTrusted Source that fish oil, due to its anti-inflammatory properties, appeared to help stabilize atherosclerotic lesions.

The AHATrusted Source recommend eating fish, and especially oily fish, at least twice per week. They say that this may reduce the risk of cardiovascular disease. 

However, in 2012, a reviewTrusted Source of 20 studies involving almost 70,000 people found “no compelling evidence” linking fish oil supplements to a lower risk of heart attack, stroke, or early death.

Vision loss and eye health

Some evidence suggests that getting an adequate intake of omega-3 may help protect eye health.

In a 2012 study, mice that received omega-3 supplements for 6 months appeared to have better retinal function and a lower risk of age-related vision loss than mice that did not receive the supplements.

Optometrists often recommendTrusted Source taking omega-3 supplements to support eye health, even though scientific evidence does not always support their use for this purpose. In some cases, eating a healthful diet may be more beneficial than taking supplements, according to some experts.

In 2019, for example, scientists who looked at the data of 4,202 peopleTrusted Source in Holland found that those who consumed fresh fruits and vegetables and 2 weekly servings of fish were less likely to develop age-related macular degeneration compared with those who did not.

Some people use omega-3 supplements for dry eyes. In 2018, however, a year-long studyTrusted Source involving 349 people with moderate-to-severe dry eyes found no evidence to suggest that taking supplements was more helpful than taking a placebo for this purpose.


Epilepsy is a neurological condition. Some studies have suggested that taking omega-3 supplements may help reduce the number of seizures a person experiences. 

However, a 2018 reviewTrusted Source did not find conclusive evidence to suggest that this can help prevent symptoms.

Healthy fetal development

Omega-3 consumption may help boostTrusted Sourcefetal development, especially of the brain and eyes. This is one that reason experts recommend consuming oily fish during pregnancy.

However, it is important to avoid eating fish with high levels of mercury, such as shark and king mackerel, during this time.

In 2011, scientists concluded that consuming omega-3 during pregnancy may improve memory function in school-age child
