What ResBiotic does
ResBiotic Nutrition, Inc. is a physician-developed microbiome health company headquartered in Birmingham, Alabama, that formulates and sells clinically validated probiotics, prebiotics, and postbiotics organized around its proprietary Gut-X Axis framework — a methodology that maps connections between gut microbiome composition and systemic organ health across the gut-lung, gut-heart, gut-brain, gut-metabolic, and gut-hormonal axes. The product portfolio includes resB Lung Support Probiotic (flagship, #1 physician-recommended lung health probiotic), resM GLP-1 Postbiotic, resG prebeet ENERGY Prebiotic, resW Perimenopause Support, and resO Bone & Joint Support, each backed by 15+ proprietary ingredients, 5+ clinical studies, and 20+ global patents. In 2026 the company extended into diagnostics via a partnership with Tiny Health, launching an at-home Gut Health Test using shotgun metagenomics sequencing processed in CLIA- and CAP-certified laboratories, with results delivered within 3–4 weeks.
ResBiotic generates revenue through a multi-channel model combining direct-to-consumer e-commerce on resbiotic.com (including a Subscribe & Save subscription offering up to 60% off), one-time at-home diagnostic test sales (priced at $249 sale / $415 regular, HSA/FSA eligible), retail shelf distribution through Walmart USA and GNC, healthcare-provider channels via Fullscript and the in-house pro-formulas wholesale program, marketplace sales on Amazon, an emerging B2B proprietary-ingredient business, and international shipping to 60+ countries plus a Mexico distribution partner. The primary customer segments are individual consumers managing chronic respiratory, metabolic, hormonal, or gut-related conditions, supplemented by healthcare practitioners (372+ recommending prebeet) and influencers such as Dave Asprey and Hannah Bronfman. Pricing is positioned in the premium tier relative to mass-market probiotics (e.g., resB at $34.99 sale / $59.99 regular), with HSA/FSA eligibility, a 30-day money-back guarantee, and bundle SKUs (Core Wellness Bundle, Hormonal Relief Bundle) to drive average order value.
The company was founded by Dr. C. Vivek Lal, MD, FAAP, a double board-certified physician-scientist in microbiome research, and is led by a team including a Chief Medical Officer, Chief Marketing Officer, Chief Customer Officer, and Chief of Staff, supported by an advisory board drawn from University of Alabama at Birmingham, University of Michigan, and Harvard/Brigham & Women's. As of late 2025, ResBiotic had raised $17.5 million in total venture funding, including a $14.5 million round (September 2025) with an $8 million Series A co-led by Sororibus Capital and Biostack Ventures.
