Xanthophylls are a class of carotenoids, which are pigments found in plants that contribute to their yellow and orange colors. They play a crucial role in photosynthesis by helping to capture light energy and protect plants from damage caused by excess sunlight. Common sources of xanthophylls include leafy greens, corn, and egg yolks. These pigments are also important for human health, as they have antioxidant properties that may help protect cells from damage. Xanthophylls, such as lutein and zeaxanthin, are particularly known for their benefits to eye health, potentially reducing the risk of age-related macular degeneration.
