Lutein and Zeaxanthin Linked to Improved Emotional Health
Previous studies have linked oxidative stress and systemic inflammation to several symptoms of chronic stress. A recent study suggests that taking a dietary supplement of the anti-inflammatory carotenoids lutein and zeaxanthin isomers may help reduce psychological stress and improve measures of emotional health.
Participants in the study included 59 healthy young adults between the ages of 18 and 25 who were given either 10/2 mg of lutein/zeaxanthin isomers, 20/4 mg of lutein/zeaxanthin isomers or a placebo daily for 12 months. Psychological stress, measures of mood and blood cortisol levers were measured at baseline, 6 months, and 12 months.
At the conclusion of the study, the researchers noted significant improvements in psychological stress, serum cortisol and measures of emotional and physical health in both supplement groups.
Researchers from the University of Georgia conducted the study. It was published online ahead of print on February 15, 2017, in Nutritional Neuroscience.
Lutein and zeaxanthin are both xanthophyll carotenoids. They are also the only two carotenoids that can build macular pigment. You can increase your lutein and zeaxanthin levels by consuming more green leafy vegetables, corn, and egg yolk.
