Xanthophylls are widely used in the food industry as natural colorants, imparting yellow to red hues in products like egg yolks, poultry feed, and beverages. They are also incorporated into dietary supplements for their antioxidant properties, which support eye health by reducing the risk of age-related macular degeneration. In cosmetics, xanthophylls are added to skincare products for their potential to protect the skin from oxidative stress and UV damage. Additionally, they play a role in agriculture, where they are used in animal feed to enhance the pigmentation of fish and poultry, improving the visual appeal of meat and eggs.
