EPA vs DHA in Fish Oil Powder

May 21st, 2019

epa vs dha

Many research studies have been done around the world since the 1950s on the benefits of Omega-3 fatty acids. These essential Omega-3 long chain fatty acids include ALA (alpha-linolenic acid), DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid). From the research studies, EPA and DHA have been proven to offer a multitude of health benefits for people of all ages.

In this blog post, we will focus our attention towards the differences between EPA and DHA in fish oil powders, EPA and DHA benefits during different life stages, as well as the advantages of NovoOmega® Omega-3 fish based powder.

It is a known fact that humans cannot produce EPA or DHA. For this reason, Omega-3 fatty acids must be obtained from another source: food. The primary dietary sources of Omega-3 fatty acids are cold water fish such as salmon, mackerels, halibut, anchovies and herring, as well as plant oils. Evolutionary assessments suggest that most individuals in western countries do not consume enough fish, and thus do not get sufficient levels of Omega-3 fatty acids. Although EPA and DHA are both types of essential long chain fatty acids, they have significant differences.

Benefits of EPA

EPA, which stands for eicosapentaenoic acid, has an important role within the cardiovascular system by reducing cellular inflammation and blood clots. EPA inhibits an enzyme called delta-5-desaturase (D5D) which makes arachidonic acid (AA), an Omega-6 fatty acid. Higher levels of EPA equal lower levels of AA, resulting in decreased production of pro-inflammatory eicosanoids such as prostaglandins, leukotrienes and thromboxane.

In addition to decreasing production of pro-inflammatory eicosanoids, EPA plays an important role in preventing the buildup of plaque in arteries and improving blood flow.

From various clinical studies, EPA has been proven to boost the immune system by increasing the actions of major immune cells such as T cells and B cells. Additionally, EPA supplementation has been shown to reduce rheumatoid arthritis by reducing plaque buildup in the arteries of legs, as well as suppressing TNF alpha and IL-1B.

Benefits of DHA

DHA, which stands for docosahexaenoic acid, has a strong role in neural development and function. While EPA contains 5 double bonds and 20 carbons, DHA contains 6 double bonds and 22 carbons.

Since DHA is larger compared to EPA, it takes up more room in the membrane, and thus helps make the fluid in the membrane more fluid. Membrane fluidity is critical for synaptic function because it helps increase signal transmissions from the membrane to the nerve cells.

By increasing membrane fluidity, DHA breaks up the lipid rafts in the membranes, thus making it difficult for cancer cells to grow and spread throughout the body. Another benefit of DHA's large size is that it reduces the likelihood of low density lipoproteins, which are the bad types of cholesterol associated with heart disease, from entering muscle cells.

DHA supplementation is also necessary for brain and eye development, especially in fetal tissues, as well as promoting cell turnover. In adults, 60% of the brain is fat, with 20% of that fat as the omega-3 essential fatty acid, DHA. Research has shown that brain cells with enough levels of Omega-3 are able to help enhance disposition, focus and behavior, while supporting clear thinking and memory.

EPA and DHA For All Types of Life Stages:

EPA and DHA are both essential for infants all the way to seniors. Here is a table summarizing the key benefits for each life stage.

Pregnant Women and Infants: Pregnant women who take EPA and DHA have offspring with improved developmental outcomes. Infants usually cannot synthesize enough DHA on their own. Therefore, infant formulas should be supplemented with DHA and EPA to help with visual and neurological development.

Children and Teens: EPA and DHA in Children and teens are important for a well-balanced diet, as well as promoting brain and nervous system development.

Adults and Seniors: Both adults and seniors need to consume enough EPA and DHA to maintain cardiovascular health and cognitive function, as well as prevent inflammatory diseases and neuropsychiatric diseases.
