Puritan'S Pride Lutigold Lutein 20mg - 30 Softgels

Lutein (pronounced loo-teen) and zeaxanthin (pronounced zee-uh-zan-thin) are types of pigments found in plants called carotenoids. Carotenoids are what give many fruits and vegetables their bright red, orange and yellow colors. The name lutein actually comes from the Latin word luteus which literally means yellow. Carotenoids play vital roles in the growth and safety of many different plants but when they are consumed in a healthy diet, they offer benefits to humans as well.**
Even though they cannot be produced in the body, lutein and zeaxanthin from the diet are stored in the eyes. In fact, lutein and zeaxanthin are the only carotenoids found in appreciable levels in the macula.3 The macula is the area of the retina with a high concentration of specialized photoreceptor cells and is responsible for sharp focus on objects straight in front of you. With so much light entering the eye, and the cellular activity of sending these visual signals to the brain, the retina is an area of high oxidative stress.
Lutein helps filter out high energy blue light from the sun and artificial light before it reaches those important photoreceptor cells.** Blue light may otherwise induce oxidative stress and possible free-radical damage to the eyes. Zeaxanthin is preferentially placed in the very center of the macula. This is the area most responsible for sharp, central vision. Due to this positioning, zeaxanthin may provide additional benefits to lutein supplements for eye health.** Lutein and zeaxanthin both nutritionally support the health of your eyes to support healthy vision.**
Lutein and Zeaxanthin are not made in the body so they must be obtained through the diet. Dark leafy green vegetables are particularly good sources of lutein and it can also be found in small amounts in egg yolks and avocados.6 Dietary sources of zeaxanthin include many orange-colored foods such mangoes, orange juice, corn, and orange peppers.6 On average, Americans are estimated to get less than 2mg of lutein per day through food alone7 and the lutein: zeaxanthin ratio in the diet is about 5:1.
