The Feasibility of Omega-3 Supplementation Compared to Placebo in the Management of Long COVID Symptoms Among Healthcare Workers: A Randomized Controlled Trial

This pilot study successfully demonstrated the feasibility, safety, and tolerability of using omega-3 supplements for the treatment of long COVID syndrome. The study results did not show statistically significant improvement in the long COVID symptoms. The mean difference in the AA:EPA ratio in the placebo vs. supplement group showed a pronounced decline in inflammatory markers in the supplement group. However, our study did not show a connection between the decreased inflammatory markers and clinical symptoms. We may need a longer follow-up to understand the possible clinical benefits of the decreased AA:EPA ratio.
