First, an overview of the three types of omega-3 fatty acids, alpha-linolenic acid, EPA, and DHA. The term Omega-3 comes from the double bond of the third carbon atom at the end of the carbon chain of each of these types of fatty acids. Alpha-linolenic acid has a chain of 18 carbon atoms and is found in vegetable oils. They are typically consumed through seeds (for example flax seeds and chia), dried fruit (walnuts, almonds) and common vegetable oils. EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are 20- and 22-carbon fatty acid chains associated with fish consumption. The presence of these two factors has been linked to our physical and mental state, and deficiencies of both types have been observed to be the key to the most common human diseases, from heart disease to cognitive decline. DHA is especially important for the brain, cerebral cortex, retina, skin and testicles.
Omega-3 fatty acids are called essential fatty acids because the human body cannot synthesize them. Humans and other mammals have a limited ability to convert one of these fatty acids (alpha-linolenic acid) to the other (EPA and DHA), but fish are much better at this conversion. Dietary fish provides humans with a way to increase EPA and DHA.
People get fit and exercise.
So, when we talk about omega-3 fatty acids from fish, we are basically referring to EPA and DHA. What is the best source of these fatty acids?
Eating fish delivers Omega-3s better than supplements
Current evidence suggests that eating fish and shellfish is the best source of omega-3 fatty acids for human performance and health. This does not mean that fish oil supplements are not effective. However, studies have shown differences between populations that consume fish and those that consume fish supplements. Nutrition is an important aspect for athletes who prefer to consume fish over dietary supplements. Fish is the best source of protein on your plate and an optimal source of omega-3 fatty acids. On the other hand, fish oil supplements for regular meals usually come from the region. If you take a fish oil supplement without reducing your food intake, you will consume at least 50 more calories with a less effective dose of omega-3 fatty acids. There’s a good reason why you should eat a delicious seafood meal at least twice a week. Better.
Below are two publications from the US National Institutes of Health Library that highlight safe and effective sources of omega-3 fatty acids;

“In summary, fish consumption is more effective in increasing serum EPA and DHA levels than fish oil supplementation.”
Currently, fish is the best and generally safe source of long-chain omega-3 fatty acids: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3257669/
Typically, higher-fat fish contain more omega-3 fatty acids. However, almost all fish contain some amount of omega-3 fatty acids. Eating a variety of fish will help you achieve your goal of maintaining omega-3 levels and enjoying a variety of delicious foods. If you want to focus on only consuming Greyareia products with the highest omega-3 content, you can purchase our salmon and black fish (black cod) varieties. However, all Greyareia products contain omega-3 fatty acids and we recommend trying some of them. Using a variety of fish dishes and recipes each week will quickly have a positive effect on your health and endurance.
Improved Function In Athletes
Since omega-3 fatty acids are widely distributed in cardiopulmonary function and reduce inflammation, the human athletic body can function and have a positive effect on exercise, menstruation, rest and recovery. To use the analogy of the body as a vehicle, omega-3 fatty acids have a positive impact on the body’s “engine” as well as other important structural elements. While there are many potential benefits for athletes from general health studies, sport-specific research is also considered. Here are the examples.
