Written by Chrystal Moulton, Science Writer. Maternal intake of lutein and zeaxanthin during pregnancy was positively associated with the child's cognitive (beta = 0.003, P= 0.001), and language development (beta = 0.002, P= 0.038). Lutein is a carotenoid found in...
Higher Levels of Lutein and Zeaxanthin Linked to Reduced Likelihood of Incident Frailty
Written by Taylor Woosley, Staff Writer. Results of the study using data from the TILDA cohort shows that subjects with lower plasma lutein and zeaxanthin concentrations at baseline were cross-sectionally associated with frailty. Aging is the irreversibly progressive...
A Combination of Lutein & Zeaxanthin Beneficially Associated with Age-Related Macular Degeneration Progression
Written by Taylor Woosley, Staff Writer. Observational findings of the Age-Related Eye Diseases Study 2 show that a direct analysis of lutein & zeaxanthin vs beta carotene resulted in an HR for late AMD of 0.85 (95% CI, 0.73-0.98; P=.02). Age-related macular...
Higher Serum Lutein and Zeaxanthin Levels Associated with a Lower Risk of All-Cause Dementia
Written by Taylor Woosley, Staff Writer. Study findings using data from the NHANES III Survey (1988-1994) show that serum lutein+zeaxanthin was associated with a reduced risk of all-cause dementia, with an inverse relationship being noted between serum β-cryptoxanthin...
Lutein and Zeaxanthin Protect against Light-Induced Retinopathy in a Mouse Model
Written by Joyce Smith, BS. In a mouse model, lutein, zeaxanthin and mesozeaxanthin (L/Zi) protected retinal photoreceptors against blue light damage by mitigating oxidative stress in the endoplasmic reticulum, thus preventing photoreceptor damage and improving visual...
Botanical Combination Attenuates Light-Induced Retinal Damage
