• Can the AREDS 2 formulation for AMD be harmful to some patients?


    Question:

    Can the AREDS 2 formulation for dry AMD, which contains very high doses of zinc and vitamin E, be harmful to some patients?


    Answer:

    The AREDS 2 study carefully looked for evidence of any harmful side effects from these supplements. While the study did suggest that the substitution of lutein and zeaxathin for beta-carotene reduced the risk of lung cancer in smokers, there was no evidence of harm from the higher doses of zinc and Vitamin E.
