• Study Type: interventional

Brief 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. 1.Wear an Oura Ring continuously throughout the study
2. 2.Perform spirometry (a measurement of your lung health) daily
3. 3.Fill out short daily exercise and health logs
4. 4.Perform three timed athletic performance tests over the course of the study and record the results
5. 5.Fill out Participant Reported Outcomes Surveys three times over the course of the study
6. 6.Fill out study product surveys twice over the course of the study
7. 7.Participate in an optional exit survey at the end of the study

Outcome Measures

Primary Outcomes (5)

• Change from baseline in Composite PRO Score

  Change from baseline between placebo and study groups of the Composite PRO score. Composite PRO is comprised of 4 questions related to the participant's experience during Zone 3+ workouts. Score ranges from 9 to 45, higher scores indicating better outcome.

  From baseline to the end of treatment at 42 days

• Change from baseline in Composite PRO Question #1

  Change from baseline between placebo and study groups on question #1: Over the past two weeks, how would you rate any changes in your breathing, congestion, or overall lung health during high-intensity workouts (Zone 3+) compared to your normal baseline? Score ranges from 1 to 5, higher score indicating better outcome.

  From baseline to end of treatment at Day 42

• Change from baseline in Composite PRO Question #2

  Change from baseline between placebo and study groups on question #2: Over the past two weeks, how would you rate your ease of breathing during high-intensity workouts (Zone 3+)? Score ranges from 1 to 5, higher score indicating better outcome.

  From baseline to end of treatment at Day 42

• Change from baseline in Composite PRO Question #3

  Change from baseline between placebo and study groups on question #3: Over the past two weeks, how often do you experience the following during high-intensity workouts (Zone 3+): Shortness of breath, Chest tightness, Wheezing, Coughing, Fatigue or difficulty maintaining intensity, Phlegm or mucus buildup? Scores range from 1 to 5 for each element, higher score indicating better outcome.

  From baseline to end of treatment at Day 42

• Change from baseline in Composite PRO Question #4

  Change from baseline between placebo and study groups on question #4: Over the last two weeks, how would you rate your ability to push yourself during high-intensity workouts (Zone 3+)? Score ranges from 1 to 5, higher number indicating better outcome.

  From baseline to end of treatment at Day 42

Secondary Outcomes (2)

• Percent change from baseline in timed performance test completion time

  From baseline to end of treatment at Day 42

• Percent change from baseline in power output during timed performance test

  From baseline to end of treatment at Day 42

Study Arms (2)

L Max Arm

ACTIVE COMPARATOR

Participants will complete up to a ten week study consisting of screening period, pre-study preparation period, baseline period, a 4-week product use period. Screening assessments, baseline questions, participant reported outcome surveys, exercise, health, and dosing logs, and adverse event reporting will be collected. Participants will have the option of participating in an end of study interview. This study will be conducted remotely and will use a web-based data collection platform, Consumer Health Learning and Organizing Ecosystem (Chloe), by People Science where participants will complete study assessments using the Chloe app during the course of the study. Participants will receive the study product during the pre-study preparation period. Demographic and limited medical history data will be collected for the study.
