Bio-K+ Expands Pro Line to Walmart, Costco.ca
The probiotic brand extends its Pro Line into the club channel for the first time while growing its retail footprint across North America.
Updated on Nov. 3, 2026 in Consumer Goods
Bio-K+ has expanded its Pro Line, including Antibio Pro and IBS Pro capsules, to Walmart and Costco.ca. The move marks the Pro Line's first entry into the club channel.
Why it matters
Expanding retail presence is part of Bio-K+'s long-term growth strategy, giving Canadian shoppers more places to buy its probiotic products. The company develops and manufactures select products at its vertically integrated facility in Laval, Quebec.
The retail footprint now includes roughly 500 Sprouts Farmers Market locations and more than 340 Circle K stores in Ontario, according to the company's release. The release does not disclose revenue, unit sales, or pricing for the new Walmart and Costco.ca listings.
The players
Bio-K+
A Canadian probiotic company with 30 years of research and leadership history, known for its vertically integrated manufacturing in Laval, Quebec.
Walmart
A multinational retail chain that is one of the largest retailers in the world, now carrying the Bio-K+ Pro Line.
Costco
A multinational membership warehouse club chain, through which the Bio-K+ Pro Line is entering the club channel for the first time.
The details
Bio-K+ expanded its Pro Line, including Antibio Pro and IBS Pro capsules, to Walmart and Costco.ca. The company also expanded its shelf-stable probiotic capsules and Kids Stick Packs across Albertsons Companies, and added Harris Teeter, while launching Active Probiotic Shots in Strawberry and Raspberry flavours at Circle K locations in Ontario in July.
Timeline
March 2026: Bio-K+ joined iHerb.
July 2026: Active Probiotic Shots launched at Circle K stores in Ontario.
August 2026: Bio-K+ expanded into Vitacost.
October 29, 2026: The company issued the press release announcing its retail expansions.
Market Landscape
The expansion follows a sequence of channel additions, from iHerb in March to Vitacost in August, that moves the brand from specialty retail into mass and club formats. It places Bio-K+ alongside other Canadian probiotic brands competing for shelf space in the same big-box and club channels.
Canadian shoppers can now find the Bio-K+ Pro Line at Walmart and Costco.ca, which may make the capsules easier to buy in bulk or alongside other groceries. The release does not indicate whether prices at these retailers will differ from those at pharmacies or grocers.
The takeaway
Retail distribution is widening for Bio-K+, so Canadian readers who already buy probiotics may find the Pro Line in more places. Checking prices and availability at Walmart and Costco.ca before purchase is a practical next step.
