VSL® Probiotics Expands to Mass Retail with Walmart Launch, Bringing Science-Backed Microbiome Support to More Consumers

First-ever retail rollout of VSL4 ® supplements reaches more than 1,500 Walmart stores nationwide

LAFAYETTE, Colo., May 19, 2026 /PRNewswire/ -- Actial Nutrition, the U.S. distributor of VSL ® Probiotics, today announced the first major retail expansion of its VSL4 ® probiotic supplement line through its launch at Walmart. VSL4 ® Gut and VSL4 ® Vaginal Health are now sold at more than 1,500 Walmart locations nationwide, marking the first time VSL4 ® products are available in physical retail stores in every state.

VSL4 ® Gut and VSL4 ® Vaginal Health are developed by the makers of VSL#3 ®, the #1 gastroenterologist-recommended multi-strain probiotics brand. 1 While VSL#3 ® is a medical food distributed through pharmacies and online for the dietary management of certain serious GI issues, such as IBS, VSL4 ® products are convenient, shelf-stable daily probiotic supplements designed for everyday wellness support. 2 This Walmart rollout extends VSL ® Probiotics' legacy of science-driven microbiome solutions to a broader audience at an accessible price point.

The rollout includes two SKUs designed for specific wellness needs:

Both products are priced at $28.97, reflecting a shared commitment to making premium, science-backed probiotics accessible to a broader range of consumers without compromising on potency, quality, or targeted formulation.

"VSL ® Probiotics products are built on a foundation of science, clinical credibility, and a deep understanding of the microbiome, and this expansion into Walmart represents a pivotal moment in making our VSL4 ® line more accessible. After strong growth in our direct-to-consumer channels, we're thrilled to bring VSL4 ® Gut and VSL4 ® Vaginal Health into brick-and-mortar to meet consumers where they are, without compromising on the potency, quality, or targeted formulations that define our brand. We're excited to bring VSL4 ® to Walmart to help more people take a proactive, informed approach to their overall health."

— Jeremy Goldstein, CEO, Actial Nutrition

Consumer interest in microbiome-focused supplements is growing rapidly, and the Walmart launch positions VSL ® Probiotics to meet that demand where it matters most — on the shelves of America's largest retailer. The expansion builds on the recent introduction of VSL4 ® Vaginal Health and reflects the brand's commitment to making precision-formulated, science-backed probiotics accessible to a broader audience.
