The substances that perform the beneficial functions of omega-3 are eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids. Omega-3 is synthesized through alpha-linolenic acid (ALA) which undergoes an enzymatic reaction and gives rise to the fatty acids EPA and DHA. EPA presents anti-inflammatory action through the production of substances called prostaglandins E3. Its main benefits are related to cardiovascular health and circulatory problems. DHA is a great food for the brain, since half of it is made up of fat. Among its benefits, what stands out is related to the improvement of cognitive processes, such as the functioning of memory and the correct functioning of neurons, acting in a neuroprotective way. For health in general, supplementation containing 3 parts of EPA is recommended for every 2 parts of DHA, for example, for each 300mg of EPA, 200mg of DHA. This ratio replicates the amount of EPA and DHA found naturally in oily fish from deep and cold waters. However, depending on the goal, their proportions may vary. So far, for example, it has been known that when there is a need for a general enhanced anti-inflammatory action, a higher proportion of EPA is recommended, and when more brain and eye-directed action is desired, higher amounts of DHA are recommended Given this information, I believe that this supplement is the best or one of the best in the market.
