Zeaxanthin & Alzheimer's Disease
Study Shows Link Between Zeaxanthin & Cognitive Function
A new study has shown that taking zeaxanthin supplements may help preserve memory and other brain functions, helping to prevent the onset of Alzheimer's Disease.
 Researchers in France have discovered a significant link between carotenoid levels in the blood and cognitive function, according to a new study published in the Journal of Gerontology: Medical Sciences. The study, titled "Plasma Carotenoid Levels and Cognitive Performance in an Elderly Population: Results of an EVA Study," was conducted over nine years and included a population of more than 1,300 healthy, elderly people in France. Results showed that participants with the lowest cognitive function were more likely to have low levels of zeaxanthin (primarily) and lycopene (to a lesser extent).
While the authors of the study said that more research is needed, one possible explanation for the positive effect of zeaxanthin is that it stops the formation of the harmful free radicals in the brain that seem to be associated with diminishing mental abilities. Zeaxanthin is found in certain fruits and vegetables, including corn, green leafy vegetables and oranges. But supplementation is important to make sure the body has enough zeaxanthin to reap the benefits.
