A new study which ties together brain and eye health benefits of the carotenoids lutein and zeaxanthin, found these nutrients may boost visual processing speed even in young people. Zeaxanthin by itself or in combination with Lutein and Omega 3 increased visual motor reaction by 10% in comparison to a placebo.
In 1994 the link between lutein and eye health was initially reported. Since that time, many studies have shown support for the benefits found between lutein and brain health. Researches point out that 60% of the total carotenoids in pediatric brain tissue is lutein however only about 12% of this carotenoid is found in our everyday diet.
64 healthy young individuals participated in this new study. Participants were separated into one of three groups randomly. The first group was given a placebo, the second group took a 20 mg zeaxanthin supplement daily and the last group was given a combination of lutein (8 mg), zeaxanthin (26 mg) and Omega 3 (190 mg). Subjects in the third group had increases in critical flicker fusion (CFF-linked to visual acuity) of 12% and visual motor increases of 10% in comparison to the first group. CFF has been linked with cognitive performance.
