Omega-Cold Supplementation With Free Fatty Acids for the Prevention of Respiratory Infections in Adults.
400 participantsStarted 2025-12-19
Plain-language summary
The purpose of this study is to investigate whether fish oil containing free fatty acids affects people's susceptibility to viral infections such as colds, influenza, and COVID-19, as well as the course of these illnesses. Omega Cold is purified fish oil with 2% added free fatty acids, making it similar in that respect to less-purified fish oils. Participants aged 18-80 in generally good health will be recruited through Matís' consumer mailing list and social media advertisements. A total of 400 participants are planned: 100 in the winter of 2025-2026 and 300 in the winter of 2026-2027. Participants will be randomly assigned to two equal groups. One group will take Omega Cold orally twice a day for four months, while the other receives a placebo (vegetable oil) taken in the same way. They will not be asked to change any other habits. All participants will report weekly on their health and any cold or flu symptoms during the time they take the oil, using short questionnaires. The study is scheduled to begin in December 2025, when the oil will be sent to participants.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1This trial is testing omega-3 fatty acid supplementation to try to prevent respiratory infections — given my specific health situation, does my doctor think this kind of nutritional approach makes biological sense for me, or would other prevention strategies be a better starting point?
2Since the trial is listed as 'not yet recruiting,' what's the realistic timeline for it to open, and is it worth waiting to see if I'm eligible, or should we focus on options available to me right now?
3The study is measuring how often respiratory infections happen, how long they last, and how severe they are — how would my doctor track those things for me during a trial like this, and would it require a lot of visits or monitoring on my end?
4This trial has no assigned phase, which suggests it may be an early or exploratory study — what does that mean for how much is already known about whether this supplement is safe and effective compared to something with a longer track record?
5Are there any standard preventive measures — like vaccines or existing supplements — that my doctor would recommend I try first before considering enrollment in a study that hasn't even started recruiting yet?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
