Written by Greg Arnold, DC, CSCS. Supplementation with three carotinoids, lutein, zeaxanthin, and mesozeaxanthin, for 12 months significantly improve macular pigment ocular density, decrease glare severity, and improved photostress recovery time in study participants. (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.
