Lutein

International Numbering System (INS) for Food Additives: 161b

 Food additives Europe numbers: E161b 

Lutein is a naturally occurring substance called a carotenoid. Carotenoids are pigments that give some fruits and vegetables their yellow, orange, and red colors [1]. But lutein has another important role – it acts as an antioxidant that protects your eyes [1, 2].

Here's a breakdown of the key benefits of Lutein for eye health:

• Protects from Age-Related Macular Degeneration (AMD): AMD is a leading cause of vision loss in older adults. Lutein, along with another carotenoid called zeaxanthin, may help prevent or slow down the progression of AMD by filtering harmful blue light and acting as antioxidants [1, 2].
• General Eye Health: Some studies suggest that lutein may also play a role in protecting against cataracts, another eye disease that can cause vision problems [2].

How We Get Lutein:

• Dietary Sources: The best way to get lutein is through your diet. Leafy green vegetables like kale, spinach, and collard greens are particularly rich in lutein [1, 2]. Other dietary sources include egg yolks, corn, and some fruits like oranges.
• Supplements: Lutein is also available as a dietary supplement, but it's generally recommended to get your nutrients from food sources whenever possible.

Important to Know About Lutein:

• Generally Safe: Lutein is considered likely safe for most people when consumed in amounts typically found in foods [3].
• Limited Research on Supplements: While supplements are available, more research is needed to determine the long-term effects of high-dose lutein supplementation [3].
• Consult a Doctor: If you are considering taking lutein supplements, talk to your doctor first to discuss if it's right for you, especially if you have any underlying health conditions or take other medications.
