Before we start hunting for suppliers, let's make sure we're all on the same page about what lutein is. Lutein is a type of carotenoid—a natural pigment found in plants that gives fruits and vegetables their bright colors (think leafy greens, corn, and egg yolks). But here's the kicker: your body can't make lutein on its own, so you have to get it from your diet or supplements. And while it's found in various tissues, its biggest claim to fame? It's a rockstar for your eyes.
You've probably heard of "macular pigment"—that's the yellowish spot in the center of your retina that helps focus light. Lutein, along with its cousin zeaxanthin, is a major building block of that pigment. Together, they act like tiny bodyguards for your eyes, filtering out harmful blue light (hello, screen time!) and protecting against oxidative damage. That's why eye doctors often recommend lutein for maintaining long-term eye health.
