Pioneers of the ‘Gut-X Axis’
The physician-scientists behind res were among the first to sequence targeted restoration. By breaking down the fiber in the gut, we influence the dynamic connections between gut health and targeted bodily functions. This method allows us to deliver targeted benefits through our clinically- studied pre/pro/post-biotic supplements.
Our founder, Dr. Vivek Lal, is a double board-certified physician, an authority in NIH-funded microbiome research, and an experienced entrepreneur who previously launched Alveolus Bio, a company that develops FDA-approved pulmonary therapeutics. He also served as the Director of Clinical Innovation and Director of the Microbiome Lab at a top US research University. Together with our team of scientists, we’ve researched the microbiome's role in regulating respiratory pathways, and the first blend that scientifically supports lung structure and function through the Gut-Lung axis was developed: resB Lung Support Probiotic. Since then, the same team has developed new formulations for other health targets to be launched by res.*

Quality Promise
We understand that not all pre/pro/post-biotics are created equally, and we’re setting a higher standard for our quality, research, and potent formulations. Our team’s scientific foundation ensures that our supplement development undergoes rigorous scientific analysis and testing, enabling us to deliver the highest-quality probiotic and prebiotic supplements.
Ingredient Sourcing
Our ingredient library and probiotic strains are maintained with proprietary deposits, all backed by live models (in vivo), human cellular laboratory research (in vitro and ex vivo), safety, and proof-of-concept data. In addition, all our formulas has undergone extensive clinical trials for safety and efficacy. Our blends are formulated by optimizing indicative biomarker responses in human tissue cells to optimize benefits across formulation.
Proprietary Formulas
Our globally patented or patent pending formulas contain ingredients produced in cGMP (Current Good Manufacturing Processes) environments by FDA-certified suppliers, specifically processed for extended stability and formula longevity. Our prebiotic, probiotic, and postbiotic ingredients and botanical extracts combine to create unique formulations tailored toward targeted systemic benefits, such as lung health, gut health, and metabolic support.
Production & Manufacturing
res blends are produced via blending and biofermentation by optimizing fermentation temperature, pH, mother culture purity, ingredient stability, and other factors. Ingredients are evaluated and precision blended to yield a consistent result every time. We manufacture in the USA under the most stringent quality checks.
Quality & Fulfillment
Every batch is analyzed for impurities and pathogens and precision blended according to current Good Manufacturing Practices (cGMP) from FDA-complaint manufacturing facilities. It is then sent to you from our FDA-registered fulfillment center. We only release supplements to the public that have met stringent quality, purity, and analytical testing requirements.

Answers to all your questions
What is the Gut-X Axis?
Our gut is our body's most immunologically active organ, communicating with different organ systems. What we consume in our gut acts as the entry point to several systemic connections. The gut-X axis denotes the axis or connections by which the gut communicates with various systemic organs or functions. The X could stand for the lungs, such as in the gut-lung axis, the heart in the gut-heart axis, the brain in the gut-brain axis, and so forth.
How long does it take to see benefits?
While people often report gut health benefits as early as their first week, systemic benefits can take longer. Some community members report breathing, circulatory, and energy benefits within six days, while others after 60-90 days. This variability can be attributed to many factors, including the importance of continuous daily use and the reality that some of us constantly think about how our bodies are feeling. In contrast, others go about their day without much thought.
How long until I get my order?

Who is resB for?
Anyone 18+ who wants to prioritize their gut, lung, and immune health!
resB Lung Support Probiotic is a top physician-recommended and formulated supplement for continuous respiratory care. Customers use resB Lung Support Probiotic for respiratory structure and function support, cough relief, lung detox, and mucus relief.
Is resB Lung Support Probiotic 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 before adding new supplements to your routine.
Can I take resB Lung Support Probiotic for COPD, Bronchitis, Pulmonary Fibrosis, or Asthma? *
The resB Lung Support Probiotic formula is based on over 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.
Can resB Lung Support Probiotic help smokers or people who vape?
This probiotic lung support was created with smokers and their lung health in mind. Our clinical trials also included smokers who developed lung problems such as asthma and COPD. We strongly encourage smokers to try quitting smoking to take control of their lung health. Also, no supplement can claim any specific conditions. We recommend you check with your doctor or pharmacist before starting any new dietary supplement.
What is GLP-1, and does resG prebeet increase GLP-1?
GLP-1 is Glucagon Like Peptide -1, a hormone that naturally delays gastric emptying and reduces appetite. GLP-1 has been made famous recently by Hollywood for weight loss functions.
resG prebeet has been shown to naturally increase GLP-1 in preclinical studies.¹
¹GLP-1 boost seen in human cellular studies.
