Abstract:

Background: Omega-3 supplementation has shown promising results in the treatment of Olfactory Dysfunction (OD). This systematic review assessed the effects of omega-3 supplementation on OD. Methodology: A systematic literature search of Medline, Scopus, the Directory of Open Access Journals (DOAJ) and Google Scholar was conducted. Studies eligible for inclusion were Randomized Controlled Trials (RCTs) that included patients with OD whether received omega-3 or did not. The primary outcome measure was omega-3 effectiveness in improving olfactory dysfunction symptoms. Results: Three studies including 175 participants were included in this review. Of the three studies performed on patients with OD, two concluded that omega-3 supplements could act as a protective factor against the loss of olfaction over a period of at least three months. In contrast, a randomized clinical trial performed on COVID-19 patients stated that patients on omega-3 supplements showed insignificant improvement in olfactory function (p>0.05). However, a significant reduction in ESR and CRP serum levels was observed two weeks after omega-3 intake (p=0.02, p<0.001, respectively). Conclusion: Administering omega-3 supplementation improved olfactory function. However, omega-3 supplements have been administered along with olfactory training or nasal rinses with saline irrigation. Further studies are needed to investigate the therapeutic efficacy of omega-3 supplementation for the treatment of OD.
