That is a great question, . I know that I cannot take zinc, so I take lutein and zeaxanthin separately (not in the AREDS formula). I also take omega 3 fatty acids daily, two probiotics (yay for gut health/overall body health!), CoQ10, and a daily multivitamin that covers the basics of the vitamin alphabet. If you're interested in more information about vitamin supplementation and health benefits of certain nutrients, please feel free to reach out. We would love to help in any way!
