Lutein

Overview:

Lutein is a carotenoid with antioxidant properties, known for its role in maintaining eye health. It is often included in supplements to support vision and protect against age-related macular degeneration (AMD).

Sources:

Lutein is found in high amounts in green leafy vegetables such as spinach, kale, and collard greens. It is also present in egg yolks and corn. Lutein supplements are available as standalone products or in combination with other eye-supportive nutrients.

Functions:

Eye Health: Lutein accumulates in the retina, particularly the macula, and helps filter harmful blue light, protecting the eyes from damage.

Antioxidant Properties: It acts as an antioxidant, neutralizing free radicals and reducing oxidative stress in the eyes and skin.

Skin Health: Lutein may improve skin hydration and elasticity, providing protection against UV-induced damage.

Deficiency:

There is no established deficiency state for lutein as it is not considered an essential nutrient. However, insufficient intake may increase the risk of AMD and other eye-related conditions.

Toxicity:

Lutein is considered safe with no known toxicity at typical dietary or supplemental levels. Excessive intake from supplements can lead to carotenodermia, a harmless condition causing yellowing of the skin.
