A review by Fenton et al. shows how the cell membrane composition of omega-3s can affect the immune system and all bodily systems if it is either too high or too low see Figure 4 below.

With regard to the immune system, an omega-3 deficiency could result in excessive and damaging inflammation while an excessive omega-3 blood level could result in a lack-luster inflammatory response to an infection.

Such alterations may be beneficial for the prevention and treatment of atherosclerotic and inflammatory diseases but may be detrimental with regard to host defense against invading pathogens. So these two reports raise the possibility — but certainly do not prove — that omega-3s might make it tougher to ward off infections.

What we need is a large study where thousands of people were given omega-3 or placebo and the effects on infections and respiratory diseases was tracked. Thankfully, we have a study like this that studied the effects of 4 grams of EPA on the occurrence of diseases over five years.

The study was called REDUCE-IT and the reported effects of EPA vs placebo on several infection-related diseases from the Supplementary Data section is shown below in Table 1. What these data show is that there was no effect whatsoever of EPA treatment on any of these conditions, which offers strong evidence that EPA does NOT, in real life as opposed to a test tube , increase risk for infection.

But likewise there is no reason to believe from this study that high dose EPA will decrease risk for respiratory infections either. To date, the precise definition of an omega-3 blood level that is too high is relatively unknown.

Higher blood levels of omega-3s have been associated with lower risk of dying from any cause , although most of that data was collected in a time with vaccines for most known infectious diseases.

The link between Omega-3 Index levels and the severity of COVID symptoms or lethality is a question we are hopefully going to start researching very soon. In the future, the study, published in the journal Clinical and Translational Medicine, could lead to a complementary, cost-effective treatment for COVID It can lead to a so-called systemic inflammatory storm, which worsens the disease state and can cause complications such as sepsis and heart failure.

Researchers at Karolinska Institutet, among others, have now shown that omega-3 fatty acids can stimulate active healing of inflammation, without inhibiting the immune response. The study was conducted in , at an early stage of the pandemic when there were no vaccines available.

The study looked at 22 elderly hospitalised COVID patients, one-half of whom were randomly assigned to intravenous treatment with omega-3 fatty acids for five days and the other half to intravenous administration of corresponding volumes of saline.

Edited by: Philip Calder , University of Southampton, United Kingdom.

Boosting your immune system is one of the most beneficial steps that you can take to enhance overall health, and now more than ever we would like to do what we can to optimize our health. One of the foundational approaches is to ensure that your diet is healthy, balanced and replete with fresh whole foods.

And with an emphasis on balance , there are several nutrients that are vital for the immune system to function effectively. Back in the s, scientists discovered that a balance of essential fatty acids played a part in the functioning of the immune system.

This research went largely unnoticed because of the seeming lack of fatty acid deficiency in the population.

Many people are aware of the heart-protective qualities of omega-3s, however, more recently researchers have been looking into using fatty acids to support healthy inflammation and immunity. Omega-3 polyunsaturated fatty acids n-3 PUFAs are part of the building blocks of cell membranes.

They are also known as EFAs essential fatty acids because they cannot be created in the body, and as such must be consumed in the diet. N-3 PUFAs are made up of a kind of fat also known as a lipid. Lipids are compounds that have poor solubility in water.

The lipid-solubility of a cell membrane influences how easily particles can permeate the cell wall. Therefore, consuming omega-3 fatty acids strengthens the cell walls, including the membranes of the immune cells.

Although omega-3 fatty acids are great for overall health, you must make sure that you look for the most pure products available.

Fish can absorb contaminants from their environment, such as heavy metals, chemicals, and microplastics. For this reason, care should be taken to find foods, or supplements that are free from these contaminants. Omega-3 fatty acids are susceptible to oxidation , and as such must be carefully handled and stored so that their beneficial properties are kept intact.

The bioavailability of omega-3s is highest when the source is pure and the producer takes great care to ensure that the fish oil is tested for contaminants.

Your immune system is your body's defense system; it fights off foreign particles that enter the body to ensure that all systems are functioning smoothly.

Interestingly, the immune system has a memory that is used to ward off pathogens that it has experienced in the past. We used to think that omega-3s simply suppressed inflammation, due to the action of docosahexaenoic acid DHA and eicosapentaenoic acid EPA , but recent research shows a more detailed influence.

One study published in the Journal of Leukocyte Biology in found that DHA- and EPA-rich fish oils enhance the function of B cells. B cells are a type of white blood cell produced to fight pathogens and ward off disease.

Omega-3 fatty acids consumed via the diet incorporate into the cellular membranes the area that separates the interior and exterior of cells , which includes your immune cells, thereby enhancing cell function. Immune cell membranes change when fatty acids are consumed.

Recently, scientists have found that omega-3 fatty acids can help remodel the cell membrane or lipid rafts in T-cells immune cells , which means that consuming omega-3s can strengthen the immune cells.

How Omega-3s Can Help Your Body Eliminate Pathogens. A type of white blood cell called a macrophage plays a key role in eliminating pathogens from your body. They patrol a wide range of organs in your body for invading pathogens.

After they recognize a pathogen they recruit other immune cells from both the innate and adaptive immune systems, so that they can mount an effective immune response. Omega 3 helps maintain the health of your heart 2 , brain 3 , eyes 3.
