  • Microbiome (n): A community of commensal, symbiotic, and pathogenic organisms that share our body space.

    Did you know there could be as many bacterial cells as there are human cells in a healthy human body? From the moment we take our first breath, the world around us is influencing our microbiome. And in turn, our microbiome is influencing our health.

  • Probiotics aren't just for your gut anymore.

    People have been consuming live probiotics for gut health for centuries. In more recent decades, scientists have discovered that gut microbes also play important roles in other bodily systems – from immune response, to mental wellbeing, and even lung health!

  • Pioneers of the Gut-Lung Axis

    The physician scientists behind ResBiotic were among the first to sequence the lung microbiome, and to examine the dynamic connections between gut and lung health. Founder Dr. Vivek Lal and Chief Medical Officer Dr. Amit Gaggar collaborated to better understand the role of the microbiome in regulating inflammatory pathways, and developed a blend that supports lung structure and function through the gut-lung axis.*

  • Our Flagship Formula

    A proprietary combination of clinically studied probiotic strains and anti-inflammatory herbs, scientifically engineered to support lung structure and a healthy inflammatory response.*

Not All Probiotics Are Created Equal

The Highest Standards for Quality & Research

From strain validation and product formulation to testing, we’re collaborating with leading scientists and research partners to develop the first microbiome-based nutritional interventions for lung health.

  • Strain Development

    Our strain bank is maintained with ResBiotic's own proprietary deposits, all backed by clinical (in vivo) and laboratory (in vitro) proof on concept and safety data. Our blend is formulated by optimizing indicative biomarker responses in tissue cells to better optimize support for the lungs. All of our strains have had their full genomes sequenced.

  • Botanical Formulation

    Each capsule contains ancient botanical extracts produced in a cGmP (Current Good Manufacturing Processes) environment by FDA-certified suppliers, specifically processed for extended stability and probiotic longevity. The combination of probiotics and botanical extracts combine to create a truly unique formulation, tailored toward lung support.

  • Production

    ResBiotic's strain blend is produced via biofermentation at massive scale through optimizing fermentation temperature, pH, mother culture purity, and other factors. Each strain is enumerated and precision-blended to yield a consistent colony forming unit (CFU) count in each capsule, every time.

  • Quality

    Every batch is analyzed for impurities, precision-blended according to current Good Manufacturing Practices (cGMP) from FDA-compliant manufacturing facilities, and sent to you from our FDA-registered fulfillment center. We only release to the public products that have met stringent quality, purity, and analytical testing requirements.

Clinical Studies

Completed and ongoing studies of resB® Lung Support include

This was a randomized, open-label clinical trial in Cork, Ireland with healthy and asthmatic patients who took one resB® capsule twice daily (one in the morning, one at night) for one month.

Primary outcomes include testing safety measures. All participants tolerated the blend without adverse events.

Exploratory outcomes investigated changes in gut microbiota, serum MMP-9 and cytokines, CRP, lung function, oxygen levels, and changes in quality of life.

Completed 2022 – View Results

This is a multi-center randomized control trial in the United States with a dosing period of three months.

Primary outcomes center on change in quality of life.

Exploratory outcomes investigate clinical improvement markers (e.g., FEV1/FVC), gut and
lung microbiota, systemic and pulmonary biomarker changes (e.g., MMP-9, CRP,
cytokines, etc.)

This is a single-center randomized control trial in India with a dosing period of 14 days.

Primary outcomes center around pneumonia incidence and prognosis in elderly population in an acute care setting.
