Our Science

res is cultivating Gut-X Axis restoration. The Gut-X Axis is how the gut communicates with our entire body to support specific organs. We deliver targeted benefits.

Following our gut means prioritizing values for optimal absorption and meaningful health:

Results

As scientists and doctors, evidence-based data drives our formula development. This allows us to deliver long-term, targeted health improvements across your Gut-X Axis. 

Candor

Direct, open, and honest communication builds trust across our communities. We welcome your feedback to optimize the probiotic and prebiotic benefits to maxamize your long term health impact. 

Holistic Restoration

The Gut-X Axis is our foundation. It guides our formulation, offering holistic health interventions that start in the gut and reach far beyond for targeted benefit.

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 axiswas 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, resB® Lung Support Probiotic 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.
