    Christen WG, Glynn RJ, Manson JE, MacFadyen J, Bubes V

    Published in Ophthalmology

    Methodology

    Randomized double-blind placebo-controlled trial of a daily multivitamin over an average 11.2 years

    Key Findings

    Cataract incidence was modestly lower with multivitamin: 872 vs 945 cases, HR 0.91 (0.83-0.99, P=.04); no benefit for visually significant AMD

    Conclusions

    Long-term daily multivitamin use modestly reduced cataract risk in older men

    Limitations

    Male physicians only, self-reported endpoints, borderline effect size

    Supplements Studied

    These randomized trial data from a large cohort of middle-aged and older US male physicians indicate that long-term daily multivitamin use modestly and significantly decreased the risk of cataract.
