WHAT ARE ESSENTIAL FATTY ACIDS?
EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid) and DPA (docosapentaenoic acid) are omega-3 essential fatty acid found in seal oil. Fish oil only contains EPA and DHA. Although DPA, EPA and DHA work together to ensure the proper functioning of the human body, scientific research has shown that each of these fatty acids have unique advantages.
10 X MORE EFFICIENT
A scientific study has shown that the maximal stimulation of endothelial cell migration by DPA pre-treatment was achieved using only 1/10 of the required EPA concentration.
These data suggest that the effect of EPA on endothelial cell migration occurs via DPA, and that DPA plays an important role in repairing damaged vessels.
OPTIMIZES OMEGA-3 INTAKE
A study conducted in 2010 has shown that the beneficial effects of seal oil supplementation were superior to those of fish oil. The two types of oil used for the experiment contained a similar amount of Omega-3. However, the fish oil was containing much more DHA, less EPA and a very small amount of DPA. After 14 days of supplementation, the total level of Omega-3 in healthy subjects increased by 41% for the those eating fish oil and 63% for those consuming seal oil. The results of this study suggest that DPA, either directly or through retro conversion through EPA, may be more effective in increasing the levels of Omega-3 in human body.
BOOSTS ALL KEY OMEGA-3’s : DPA, EPA & DHA
The models of absorption for DPA and EPA are quite distinct. A study published in the European Journal of Nutrition in 2013 shows that in just 14 days of supplementation, DPA has increased the proportions of EPA (by 3.1 times), the proportions of DHA (by 3.1 times ) and the proportions of DPA (by 2.3 times) in the triglycerides. The study also showed that unlike DPA, EPA did not alter the proportions of DPA and DHA in any lipid fraction.
Numerous large-scale epidemiological studies suggest that people at risk for coronary artery disease can benefit from an omega-3 supplementation. The benefits of EPA and DHA on the cardiovascular system led the US Food and Drug Administration (FDA) to allow a health claim linking the consumption of EPA and DHA to a reduced risk of coronary heart disease. It is recommended that people who have survived a myocardial infarction should consume about 1g per day of EPA and DHA for cardio protection purposes. The mechanism by which omega-3 fatty acids reduce the risk of cardiovascular disease is still under study. [lii]
Reduces joint inflammation
In joint and muscle tissue, EPA naturally supports healthy inflammatory levels. According to the results of a scientific study, it was recommended that patients with arthritis consume 3 to 6 g per day of dietary supplements containing n-3 fatty acids for more than 12 weeks. Supplements should not replace standard therapeutic medical treatment, but should instead be added to it. After taking omega-3 supplements for 3-4 months, patients may try to reduce their dose of medication under the supervision of a doctor. However, it is important to note that there are many forms of arthritis and that clinical studies demonstrating the efficacy of Omega-3 have been performed only in patients with rheumatoid arthritis.[liii]
A study published in the Journal of Nutrition reported a correlation between higher levels of DHA and improved cognitive performance in middle-aged adults. [liv] Several other scientific studies have shown that people who consume more DHA in their lifetime have better cognitive function as they age.
Pregnancy and breast feeding benefits
DHA is essential in the development of the brain, eyes and nerves during pregnancy and the first years of child’s life. However, pregnant women who eat raw or partially cooked fish are at risk of developing a food-borne illness, such as listeriosis. A high quality Omega-3 oil is therefore an ideal solution and is safe for pregnant women. Canada has established specific standards for all natural health products, including fish oils and marine oils. Some research have shown that mothers who consume Omega-3 have a smooth labor experience and keeps a good morale after giving birth. In addition, the child has a better immune system and performs better in a variety of tests. [lv] [lvi] [lvii]
Combat mood disorders
Since Omega-3 levels are highly concentrated in the brain, they have a significant impact on mental health. Sixty percent (60%) of our brain is fat and DHA alone accounts for about 20 percent (20%) of the cerebral cortex. [lviii] The results of a scientific study suggest that during depression, there is an abnormal metabolism of omega-3 in our brain. [lix] This is why a DHA supplementation can have a beneficial effect since we depend on our diet to get the necessary Omega-3 fatty acids in order to improve and protect our brain function.
