Lutein is a natural carotenoid, a powerful antioxidant widely used to protect and promote eye health. It absorbs blue light and UV rays to help filter harmful rays and reduce the risk of photodamage to eye tissue. It can also help maintain the health of the retina and reduce the aging of the macula. In addition to its protective effects on the eyes, Lutein is also believed to have beneficial effects on overall health. It has been found to help reduce the risk of eye diseases such as cataracts and macular degeneration. Studies have also shown that lutein can reduce the risk of chronic diseases such as heart disease and cancer. Lutein is mainly found in some plant foods, especially green vegetables and fruits, such as spinach, kale, lemon, tomato, etc. However, the human body cannot synthesize lutein on its own, so we need to get enough lutein through diet or supplements. All in all, Lutein is an important nutrient that benefits both eye health and overall physical health. Adequate intake of Lutein in the diet is very important to prevent eye diseases and chronic diseases.
