Seed, the #1 Gut Health Supplements Brand in the U.S., Launches Nationwide at Costco

The microbiome science company brings its flagship DS-01® Daily Synbiotic to all Costco locations in a Costco-exclusive 100-count format, marking its first entry into the club channel

NEW YORK, Nov. 9, 2026 /PRNewswire/ -- Seed, a microbiome science company, today announced its nationwide launch at Costco, marking the company's first entry into the club channel. Beginning today, Costco members can shop Seed's award-winning DS-01® Daily Synbiotic in a Costco-exclusive 100-count jar, a 50-day supply ($74.99).

The launch marks the latest milestone in Seed's growth as the number-one gut health supplements brand in the U.S. Over the past five years, Seed has grown revenue 13x while remaining profitable, establishing a strong omnichannel presence across Amazon, Target, Sprouts Farmers Market, and Erewhon. That expansion has been met with strong consumer demand, with DS-01® becoming the leading digestive health probiotic at both Target and Amazon. Costco now brings Seed into its largest retail channel yet, significantly expanding the brand's reach.

"We've been deliberate about building a business that can scale while maintaining the scientific rigor, product efficacy, and experience that define Seed," said Cathrin Bowtell, CEO of Seed Health. "Costco represents an important next step in that strategy, allowing us to bring the potential of microbiome science to even more people, with greater value and easier access than ever before."

Seed's flagship innovation, DS-01® Daily Synbiotic, reflects the company's approach to product development: translating advances in microbiome science through precision formulation, purpose-built delivery technology and rigorous clinical validation. Formulated with 24 scientifically selected probiotic strains and a prebiotic, DS-01® is clinically validated to improve regularity, reduce bloating, and alleviate gas. Its proprietary capsule-in-capsule ViaCap® technology is engineered to protect the probiotic strains through digestion and release them in the colon.

DS-01® has been evaluated in multiple human clinical trials, including the largest randomized, placebo-controlled trial on a probiotic for bloating and gas in healthy adults, published in Nutrients. By the end of the study, 72% of DS-01® participants reported never or rarely feeling bloated.

With an expanding omnichannel presence, Seed is positioned to introduce its next generation of microbiome-targeted products with greater reach and impact. The company plans to expand across both products and retail channels in the years ahead, bringing new gut-directed innovations to a growing mainstream audience.
