Hi . Welcome to the community!
Unfortunately, AREDS supplements contain no medication, so they are not regulated by the FDA. For that reason, it's really important to do some research, not only on whether the ingredients are effective, but on the manufacturer as well. Though no website or organization is 100 percent reliable when it comes to reviews of supplements, I have had good luck with consumerlab.com. I often search a couple of different sources before I buy supplements to look for agreement on the ratings.
I hope this helps and that you get input from others in the community. Maybe someone out there has already done the research. Best wishes. - Lori (Team Member)
