This ZOI brand turned to be the best, and cheaper too. Lutein is a very important for vision, my family supplements with Lutein since 2010. Sometimes a brand name would turn out to be NOTHING, and they would ask me not to get them this brand anymore. With ZOI Research they have asked me to switch most of their supplements to it :D Thank you iherb.com team :)
