Lutein: ‘the eye vitamin’

Products containing
this ingredient

Lutein stands out as an incredibly promising nutrient with a wide range of health benefits, in particular eyesight. A naturally occurring carotenoid that is primarily found in dark, leafy greens and various fruits. In recent years, lutein supplementation has gained attention for its potential to support eye health, cognitive function, and more, and is considered a valuable addition to your daily regime.

Lutein is a yellow pigment known as a carotenoid, a class of compounds found in plants. It’s present in various foods, with some of the richest sources being spinach, kale, broccoli, and corn. Lutein plays a vital role in the human body, primarily in the eyes, where it is found in the macula, a region responsible for central vision and detail. Lutein acts as a potent antioxidant, protecting the eyes from harmful high-energy light waves like ultraviolet rays. It also scavenges free radicals, which can damage cells and contribute to various diseases.

 

The eye vitamin

Lutein is often referred to as “the eye vitamin” due to its remarkable ability to support vision and protect the eyes. It has been extensively studied for its role in preventing age-related macular degeneration (AMD), a leading cause of vision loss in older adults. Lutein helps to filter harmful blue light and reduce oxidative stress in the macula, which can slow down the progression of AMD and cataracts.

Beyond its impact on eye health, lutein has shown promise in supporting cognitive function, particularly in older individuals. Studies have suggested that lutein supplementation may improve memory and cognitive performance. Its antioxidant properties help combat inflammation and oxidative stress in the brain, which are associated with cognitive decline and neurodegenerative diseases.

Lutein’s ability to neutralise free radicals also benefits the skin. By reducing oxidative stress, lutein may help prevent premature aging and skin damage caused by UV radiation. Some skincare products now include lutein as a key ingredient to promote skin health and radiance.

Emerging research suggests that lutein may have a positive impact on cardiovascular health. Lutein’s antioxidant properties help reduce inflammation and oxidative damage in blood vessels, potentially lowering the risk of heart disease. It may also improve cholesterol levels by increasing levels of beneficial HDL cholesterol.

Lutein plays a role in enhancing the body’s immune system. Its antioxidant properties help protect immune cells from oxidative stress, allowing them to function more effectively in defending against infections and illnesses.

When considering lutein supplementation, it’s essential to choose a high-quality product from a reputable manufacturer. Look for supplements that contain lutein in the form of lutein esters or lutein with zeaxanthin for enhanced absorption. The recommended daily dose varies, but a typical range is 10-20 milligrams per day for adults.
