For reducing the risk of cataracts and age-related macular degeneration (AMD): 6 mg of lutein per day, either through diet or using supplements. People consuming 6.9 to 11.7 mg of lutein per day through diet had the lowest risk of developing AMD and cataracts.For reducing symptoms of AMD: 10 mg per day of lutein supplements.
Doctor prescribed PreserVision to hopefully slow progression of disease in my husband's eyes. Dr. will retest in 6 months to see what effect, if any, it makes. Side effect: he has a dermatology issue that has been treated, unsuccessfully, by 4 dermatologists over the past 12 years. About 3 weeks after starting the lutein dosage, we noticed the swelling and inflamation in his fingers cleared and the cracks started healing. In the successive 3 weeks, his hands look better than they have in the past 12 years! For that alone, my husband will continue this supplement.
I used Lifeplan Lutein & it certainly did help my eyes (as I noticed when I stopped taking it!), but unfortunately, as someone else has mentioned, it gave me asthma. It took me a while to realise it was the lutein causing it, but I have tested a few times & it definitely was. Lutein is extracted from marigold flowers, so I don't know if that has anything to do with it.
