Lutein is a part of the xanthophyll family of carotenoids found in many green vegetables such as spinach, kale, and lettuce1. High levels of lutein can also be found in the retina of the human eye2. Lutein is a fat-soluble antioxidant often studied for its anti-inflammatory properties and support for cardiovascular health3.
