Efficacy of ω-3 supplementation in patients with psoriasis: a meta-analysis of randomized controlled trials.

Several studies have been conducted with the aim of investigating the effect of Omega(ω)-3 on different psoriasis indices including Psoriasis Area and Severity Index (PASI) score, erythema, scaling, itching, area involved, and infiltration. Nevertheless, a pooled analysis of trials that evaluated these variables has not been conducted. Therefore, the aim of this meta-analysis was to assess the efficacy of ω-3 fatty acids in treating patients with psoriasis.
