Share When Do You Need Larger Lutein Doses By Carlyle Coash Our basic recommendation for everyone is that they take 40 mg of lutein daily if the product they are using is sourced from the FloraGlo® company in Europe. It is sourced from a different manufacturer, then we recommend 80 mg each day. Lutein helps restore the pigment layer of the retina. If someone is continuing to have problems coping with glare, bright lights at night, bright sunlight or has poor night vision, we recommend they increase their dosage to 60 mg or even 80 milligrams each day if the product has FloraGlo® lutein. If the product does not contained lutein from the FloraGlo® company we recommend the higher dose be 120 to 160 mg per day. If you have macular degeneration, retinitis pigmentosa or Stargardt disease, you need lutein. Take a dose that matches the dose is shown to be effective in decades of scientific research.
