Pure Encapsulations Lutein 20mg offers support for eyes. Lutein is unique because it is one of only two carotenoids stored in the retina, which is a layer of tissue near the back of the inner eye. The retina is light-sensitive and acts like camera film, converting the images your lens sees into electric signals that are transported to the brain through the optic nerve. Spinach and other leafy greens are good sources of lutein, but getting enough through your diet can be inconvenient. Lutein 20 mg by Pure Encapsulations provides free-form lutein that is structurally similar to the natural type contained in food. With a supplement like Lutein 20 mg, you can support the density and integrity of macular pigment. The macular pigment is a yellow-colored spot that acts like a pair of sunglasses in order to protect the macula from potentially harmful blue light. This carotenoid works to screen light while providing antioxidant protection from free radicals that can cause damage to the cells involved in vision. Recommended use: 1 softgel capsule, 1-2 times daily with meals, or as directed by a healthcare professional.
