Eye Health and Cognitive Function Linked to Lutein Levels
I recently read an important article linking Lutein and brain function on Dr. Andrew Weil’s site.
Dr. Weil states that “new research suggests that the higher your lutein levels at midlife, the more likely it is that your brain will work like a younger person’s as you get older.”
The study was conducted on 60 adults between the ages of 25 and 45. Participants had the lutein levels in their eyes measured. Next, electrodes placed on the scalp measured neural activity in the brain while the participants performed a task testing attention.
Results showed that the older study participants with higher levels of lutein had neural responses that were more like younger participants.
Study leader Anne Walk, University of Illinois, noted that new findings suggest that cognitive decline can start earlier than expected and that some differences show up in the 30s. She adds that lutein seems to have a protective role in this decline.
“As people get older, they experience typical decline,” said Dr. Anne Walk, a postdoctoral scholar at the University of Illinois at Urbana-Champaign.
“However, research has shown that this process can start earlier than expected. You can even start to see some differences in the 30s.”
Most studies examining the effects of lutein have looked at its effects on eye health. The University of Michigan Health System points to one trial that found that supplementing with 15 mg of lutein three times a week for one year significantly improved visual function in subjects suffering from cataracts. The University of Pittsburgh Medical Center reports that one trial study found that taking 10 mg a day resulted in improved vision in patients with macular degeneration.
One favorite supplement which we recommend to our clients is Nordic Naturals Pro DHA Eye.
The fish oil in Pro DHA Eye provides an ideal delivery system for the lutein and zeaxanthin, and regular supplementation with Ultimate DHA Eye is a convenient way to achieve the combined benefits of these nutrients.
This formula contains 20 mg of Lutein.
