Thanks for your question. Lutein, a carotenoid found in vegetables
and fruits acts as an antioxidant. It is found naturally in leafy
green vegetables sich as spinach. There are claims that lutein
improves the health of the eyes, however, the National Eye Institute
issued a report in July of 2002 that these claims are speculative and
that the benefits of lutein are uncertain and should be viewed with
caution [http://www.nei.nih.gov/news/statements/lutein.htm]
That being said, there have been studies that show there may be some
correlation between lutein and macular degeneration. There are
ongoing studies, however, there is no "official" recommended dose.
Many websites are touting 6 to 40 mg of lutein per day. A study done
at the University of Utah showed increased levels of lutein improved
macular degeneration and "These findings are consistent with the
hypothesis that a long-term deficiency of macular carotenoids may be
associated with higher risk of AMD."

In this study, the minimum dose recommended is 4mg per day that may
have beneficial effects, but further studies are needed.
Thanks for your question. If you need any additional clarification,
please let me know prior to rating my answer.
