"Lutein is a carotenoid pigment widely recommended for eye health by NIH and other sources, and Nature's Bounty is a familiar supplement brand in pharmacies and big box stores but Lutein is not always available. I've been taking it since 2005, and believe it (and the zeazanthin that is naturally present in lutein sources) helped slow the development of cataracts caused by UV exposure and/or a lack of lutein from food sources. I had lens implants in 2018, but that's 13 years after the initial discovery of cataracts. I'm still taking it because "after cataracts" in lens capsule tissue (though not on the artificial lenses) are still possible after cataract surgery.

Lutein also has antioxidant and anti-inflammatory properties and may be generally beneficial as well as helping prevent macular degeneration. While I get some lutein broccoli, spinach and other foods, it may help to supplement for a steady level. Eggs are a good source for non-vegans. In short, I haven't experienced any downside with 20 mg lutein supplements. The Nature's Bounty gel caps are very small, made in the USA ("with select ingredients from around the world"), and have very few added ingredients, none scary. All of the Amazon shipments have had an expiration date about 2 years in the future."

"I’ve used this brand of supplement many times before but this is first time with lutein. Lutein recommended by eye doctor after cataract surgery. Time will tell if it helps prevent eye problems, like macular dev. Easy to take but must drink full glass of liquid and get that capsule all the way down. Burns if I don’t do that. I will continue to purchase this brand."
