Description
Lutein is a type of carotenoid, a pigment found in plants and vegetables. It is known for its yellow color and is often referred to as "the eye vitamin." Lutein is an essential nutrient for eye health and is found in high concentrations in the macula, a small area at the center of the retina. It helps to protect the eyes from blue light and oxidative stress, which can cause damage to the macula and lead to vision problems. Lutein is also an antioxidant, which means it can help to neutralize free radicals and reduce inflammation in the body. Food sources of lutein include leafy green vegetables such as spinach and kale, as well as eggs and corn. Lutein is also available as a dietary supplement in various forms, including capsules, tablets, and softgels. The nutrient has been shown to be safe and well-tolerated, with few reported side effects. Lutein has been the subject of numerous studies, which have investigated its potential benefits for eye health and other areas of health.
