NCT ID NCT07314593
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a special fish oil (Omega Cold) can help healthy adults avoid or recover faster from colds, flu, and COVID-19. Four hundred participants aged 18–80 will take either the fish oil or a placebo daily for four months during flu season. They will report any symptoms weekly. The goal is to see if the oil reduces how often people get sick and how severe their symptoms are.
