As Seen On

"We're creating a whole new paradigm for lung, gut and immune health. One that is proactive, holistic, and evidence-based."

C Vivek Lal, MD, FAAP
Founder and CEO, ResBiotic Nutrition

  • Our Flagship Formula

    Clinically validated resB® Lung Support 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.*

  • Doctor-Developed

    ResBiotic® is founded and led by leading double board certified practicing physicians and scientists at the University of Alabama at Birmingham.

  • Scientifically Validated

    ResBiotic® products are formulated to work on specific mechanisms of action, and validated through in vitro, in vivo, and human clinical studies.

  • Thoughtfully Packaged

    resB® is bottled with moisture control technology and acid resistant capsules to protect the live probiotics inside, ensuring consistent CFU counts in every capsule.

  • Better breathing begins in your microbiome.

    The healthy human body contains millions of bacteria, good and bad, that make up your microbiome. The scientists behind ResBiotic® have studied the balance of the microbiome as it relates to lung health for over a decade.

  • It's All Connected

    Study after study has shown correlations between an imbalanced gut microbiome and lung health risks – from cigarette smoke to seasonal allergies.*

    resB® Lung Support targets the gut–lung axis, with a proprietary probiotic blend shown to improve lung structure and function in preclinical studies.*
