A challenging math problem can stress you out. Researchers at Michigan Technological University had participants in a study do those challenging problems, measuring if and how stress levels were affected by fish oil supplements. Sixty-seven adults were examined, before and after eight weeks of taking fish oil supplements or a placebo, olive oil.
They measured heart rate and blood pressure, finding fish oil supplements helped protect the heart in stressful situations. Dr. Jason Carter led the study.
“We suggest individuals with high-stress lives might consider taking fish oil supplements or regularly consume fish high in omega-3 fatty acids at least once or twice a week.”
The study in the American Journal of Physiology was supported by the National Institutes of Health.
