Age-related macular degeneration (AMD) is the third leading cause of blindness worldwide, particularly among older populations. Macular pigment optical density (MPOD), a non-invasive biomarker, reflects the accumulation of protective xanthophyll pigments such as lutein and zeaxanthin. These pigments play a critical role in filtering blue light and reducing retinal oxidative stress.
In the absence of early curative treatments, nutritional prevention is emerging as a key strategy. Goji berries, rich in zeaxanthin dipalmitate, are drawing growing interest. This study aimed to evaluate whether regular consumption of goji berries can improve MPOD and skin carotenoid levels in healthy adults with no signs of AMD.
