How it works
The Gut-Lung Axis
The probiotic bacteria in resB® Lung Support Probiotic have been known to produce specific short-chain fatty acids that support digestive health directly and travel through systemic circulation to support respiratory health. In addition, these strains downregulate MMP9 signaling, which reduces neutrophilic inflammation - a fundamental mechanism in chronic lung conditions.*
Clinical results
resB® Lung Support Probiotic contains a proprietary blend of well-studied probiotic strains and ancient herbs scientifically engineered to support lung structure and function, gut health, and immune health.* Our extensive preclinical and clinical data obtained through rigorous in vitro testing and human clinical trials make it the only clinically studied respiratory probiotic supplement available today.
1. Preclinical in vitro & ex vivo human cellular testing
Process: resB® was tested for efficacy and benefits through live models of lung inflammation and gut concerns.
Results: resB® decreased markers of lung inflammation, and the study described the mechanisms and efficacy of resB® Lung Support Probiotic.
2. Randomized open-label clinical trial
Process: Healthy individuals, smokers, and participants with asthma took resB® Lung Support Probiotic blend twice daily for 30 days.
Results: Participants showed significant improvements in biomarkers associated with lung issues and showed improvement in lung function as measured by forced expiratory volume. Participants also noted an improvement in overall health, coughing, shortness of breath and breathing-related sleep disturbances. resB® supplementation was found to be safe for consumption with almost no adverse side effects.
3. Double-blind, randomized placebo-controlled clinical trial to evaluate quality of life
Process: Participants with COPD or Bronchiectasis took resB® twice daily for 3 months.
Results: Participants showed improvement in markers of lung inflammation and reported improvement in clinical status. resB® supplementation was found to be safe for consumption with almost no adverse side effects. Final results pending publication.

Can I take resB® Lung Support Probiotic for COPD, Bronchitis, Pulmonary Fibrosis, or Asthma?
The resB® Lung Support Probiotic formula is based on more than 10 years of rigorous research to support healthy respiratory structure and function, healthy digestion, and the immune system while keeping everyone in mind. Our ingredients and supplements have been extensively studied in many settings, including physician-supervised preclinical and clinical trials in specific conditions.
That said, no supplement can make claims regarding any specific disease diagnosis. We recommend you check with your doctor or pharmacist before starting any new dietary supplement.
Is it safe to take with other supplements and medications for COPD, Asthma, etc?
While there are no known contraindications with resB® Lung Support Probiotic and any over-the-counter or prescription medications, we encourage you to consult your primary care physician or pulmonologists before adding new supplements to your routine.
Additionally, if you are taking an antibiotic, take resB® Lung Support Probiotic at least 1 to 2 hours before or after your antibiotic dose. This is to ensure your antibiotic doesn't kill the probiotic bacteria in resB® Lung Support Probiotic before they have a chance to work!

How long does it take to see benefits?
While people often report gut health benefits as early as their first week of taking resB® Lung Support Probiotic, the systemic benefits can take longer.Some customers report breathing benefits within 6 days, others after 60. This variability can be attributed to many factors, including the importance of continuous daily use and the fact that some people constantly think about their lungs while others breathe without much thought.
