Small randomized trial in older adults compares benefits of the two in supplements — ScienceDaily

The omega-3 fatty acids EPA and DHA work differently against chronic inflammation, according to the results of a small randomized study, suggesting each has its own important role to play in regulating the immune system.

The 34-week trial, led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University (HNRCA), compared the effects of the two omega-3s in a small group of older adults with obesity and chronic low-grade inflammation.
