FloraGLO is a patented lutein extract made from marigold flowers. It uses a purified form that absorbs well. Scientists have used this specific form in many human studies on bioavailability and eye function. The compound helps build macular pigment density in the retina. That pigment acts as a natural filter for blue light and shields retinal cells from oxidative stress.
Take this supplement alongside a meal that contains fat. Eggs, avocado, nuts, or olive oil all work. Fat improves how much lutein your body takes in. Typical doses cause few problems. No major side effects or drug interactions show up at standard intakes.
