[0001] The invention belongs to the field of pharmacy, and in particular relates to lutein microcapsules and a preparation method thereof. Background technique

[0002] Carotenoids are fat-soluble plant pigments widely found in nature. Carotenoids are mainly divided into two categories: carotene and lutein. Natural lutein is also known as plant "lutein". Medical experiments have proved that lutein contained in plants is an antioxidant with excellent performance.
