Written by Angeline A. De Leon, Staff Writer. Plasma levels of carotenoids lutein, zeaxanthin, β-cryptoxanthin, and β-carotene and y-tocopherol are significantly associated with measures of cognitive and physical fitness in the participating fifty-six individuals with mild cognitive impairment.

Written by Joyce Smith, BS. A 6-month supplementation with lutein, zeaxanthin, and mesozeaxanthin significantly improved macular pigment optical density, temporal vision as well as sleep quality, contrast sensitivity, disability glare, photo stress recovery, headache frequency, and eye strain and fatigue. (more…)
Written by Greg Arnold, DC, CSCS. Participating subjects who ate one avocado a day for six months had significant increases in lutein levels, improved Short-Term Visual Memory and Sustained Attention scores as well as improved MPD, an indicator of improved cognitive function. (more…)
Written by Angeline A. De Leon, Staff Writer. Analysis of 4,076 community-dwelling adults found that higher plasma lutein and zeaxanthin were independently associated with better composite scores for global cognition, memory, and executive function; however, only zeaxanthin, was associated with better processing speed.
