Fish Oil
Fish oil is one of the greatest sources of omega-3 fatty acids. Studies have shown that omega-3 can have a great effect on lowering cortisol. A recent study looked at 7 people to see how they responded to mentally stressful tests in a period of 3 weeks. They are divided into two groups: one did not take fish oil supplements and the other did. The results have shown that fish oil can lower cortisol levels and stress. Another 3-week research indicated that these supplements are more effective than a placebo to reduce cortisol levels when participants faced stressful tasks. [8]
