Lutein and Zeaxanthin May Provide Cognitive Health Benefits
Previous research has found that the carotenoids lutein and zeaxanthin may provide eye health benefits. Now a new study suggests that lutein and zeaxanthin may also provide cognitive function benefits.
Participants in the study included 90 adults with self-reported problems in memory or attention. They received 10 mg of lutein and 2 mg of zeaxanthin or a placebo daily for 6 months. Cognitive function was assessed at baseline and at the end of the study using computer-based cognitive tasks, the Cognitive Failures Questionnaire, the Behavior Rating Inventory of Executive Function, and the Profile of Mood States.
Participants in the supplement group saw greater improvements in visual episodic memory, delayed word recall, word recognition, and visual learning compared to the placebo group.
The study was conducted by researchers from Murdoch University. It was published online ahead of print on February 17, 2021 in the journal Frontiers in Nutrition - Nutrition and Brain Health.
