EurekAlert: "The take- home message from this study is that having very low vitamin D status (25-hydroxyvitamin D blood concentrations lower than 38 nanomoles per liter) may be associated with increasing your odds of developing age-related macular degeneration," says Millen. "But based on these study findings, being at a higher vitamin D level than 38 nanomoles per liter does not appear to be more protective," she cautions.
