    Research author Emily Chew, the deputy clinical director at the National Eye Institute (which is part of the NIH), said that they did not see any benefit of omega-3 supplements for stopping cognitive decline.

    While elderly people who regularly eat food rich in omega-3 fatty acids like salmon, tuna and halibut have been shown to have better eye, heart and brain health compared to non-regular eaters, consuming the oil in pill form does not have the same effect.
