Fish Oil Blunts Adverse Cardiovascular Effects From Mental Stress

A U.S. study shows that fish oil seems to counteract the detrimental effects of mental stress on the heart. Participants who took fish oil supplements for several weeks had a blunted response to mental stress in several measurements of cardiovascular health, including heart rate and muscle sympathetic nerve activity. Future research might focus on the effects of taking fish oil for longer time periods and examining this effect on older populations or people with cardiovascular disease, the researchers said.
