2) Product Description

Lutein is a nutrient well known for its benefit maintaining eye health, though it may have other health benefits as well. It’s a carotenoid — compounds that give plants their color — found mainly in yellow and green fruits and vegetables. Lutein is also available as a supplement, and studies show it’s as effective in this form as dietary sources. Though lutein is in many foods, most people only get about 30% of the recommended level.Lutein, also known as phytolutein, is a carotenoid with the chemical formula C40H56O2, which is widely found in vegetables, fruits, flowers and other plants, and contains two ketone rings in its chemical formula, and is the main pigment present in the macular region of the retina of the human eye.

3) Health benefit of Lutein

Lutein is a fat-soluble vitamin whose absorption spectrum contains near-blue-violet light that helps protect the retina of the eye from ultraviolet light. For the eyes, lutein is an important functioning antioxidant. Supplementing the body with high levels of lutein can help maintain vision permanence, improve visual reaction time, and reduce visual damage. For nearsighted people, supplementing with lutein can slow down the increase in their nearsightedness.

3.1 Possibly Effective for

An eye disease that leads to vision loss in older adults (age-related macular degeneration or AMD). Taking lutein supplements by mouth for up to 36 months can improve some symptoms of AMD. More benefits might be seen when it’s taken for at least 3 months at doses above 5 mg, and when it’s combined with other carotenoid vitamins. But lutein doesn’t seem to keep AMD from becoming worse over time.
Cataracts. Eating higher amounts of lutein in the diet is linked with a lower risk of developing cataracts. But it’s not clear if taking lutein supplements by mouth helps people who already have cataracts.
