Themain questions it aims to answer are: ‐ Does Immune X reduce the proportion of participants who experience at least oneclinically confirmed common cold event during the study period? ‐ Does Immune X affect the number, duration, and severity of common cold events?Researchers will compare Immune X to a placebo (a look‐alike capsule containing inactiveingredients) to see if Immune X helps prevent common cold events.Participants will: ‐ Take Immune X or placebo daily for 16 weeks during the winter season. ‐ Attend study visits at the beginning and end of the study and completequestionnaires and symptom assessments throughout the study. ‐ Record cold symptoms, medications, and other study information using a smartphoneapplication. ‐ Provide blood and stool samples during the study.
