No specific omega oil has been called out specifically for “concentration” but evidence does exist showing that certain omega-3 fatty acids may help maintain brain health. The two most studied omega-3 fatty acids are the 20-carbon eicosapentaenoic acid (EPA) and the 22-carbon docosahexaenoic acid (DHA). These are the primary compounds in fish oils that scientist attribute to the health benefits of fish consumption. Because DHA is integral to the maintenance of the cell membranes in the brain and important to the overall central nervous system function, regular consumption of these omega-3 fatty acids is believed to dramatically reduce the risk of dementia, thus preserving cognitive function in the aging population and contributing to mood improvement.
