A Randomized, Placebo Controlled Trial of L Max in Healthy Adult Athletes

United States120 participantsStarted 2026-01-19

Plain-language summary

The goal of this study is to evaluate the lung-cleansing effects of L Max by measuring changes in Participant Reported Outcome (PRO) Scores and athletic performance. Researchers will compare the results of participants who take L Max and participants who take placebo (a look-alike substance that contains no active ingredient). Participants will: 1. Wear an Oura Ring continuously throughout the study 2. Perform spirometry (a measurement of your lung health) daily 3. Fill out short daily exercise and health logs 4. Perform three timed athletic performance tests over the course of the study and record the results 5. Fill out Participant Reported Outcomes Surveys three times over the course of the study 6. Fill out study product surveys twice over the course of the study 7. Participate in an optional exit survey at the end of the study

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.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

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.
