Null association between serum 25‐hydroxyvitamin D levels with allergic rhinitis, allergic sensitization and non‐allergic rhinitis: A Mendelian randomization study

Abstract

This MR study found no evidence supporting a causal association between serum 25(OH)D levels and risk of AR, AS and NAR in European-ancestry population. This argues against the previous postulation that vitamin D supplementation is effective in prevention of allergic diseases.
