New York – November 10, 2026 -- Costco members can now buy Seed's DS-01 Daily Synbiotic in a Costco-exclusive 100-count jar, a 50-day supply priced at $74.99. The launch covers all Costco locations nationwide and is Seed's first move into the club channel.
Seed Adds Costco to a Growing Retail Lineup
Seed calls itself the number-one gut health supplements brand in the U.S. and says its revenue has grown 13x over the past five years while the company stayed profitable. DS-01 already sells through Amazon, Target, Sprouts Farmers Market and Erewhon. According to SPINS data covering the 24 weeks ending in January 2026, it is the leading digestive health probiotic at both Target and Amazon (combined Amazon and Target sales).
Costco is now the company's largest retail channel yet. CEO Cathrin Bowtell said the partnership brings Seed's science to more people "with greater value and easier access than ever before."
DS-01 Combines 24 Probiotic Strains With a Prebiotic
The formula pairs 24 selected probiotic strains with a prebiotic. Seed says it is clinically validated to improve regularity, reduce bloating and alleviate gas.
The capsules use a proprietary capsule-in-capsule design called ViaCap. It is engineered to protect the probiotic strains through digestion and release them in the colon.
A Published Trial Reports 72% Rarely Felt Bloated
DS-01 has been tested in multiple human clinical trials. One was a randomized, placebo-controlled study in healthy adults, published in Nutrients, and Seed describes it as the largest of its kind on a probiotic for bloating and gas. By the end of the study, 72% of DS-01 participants reported never or rarely feeling bloated.
Seed Plans More Products and Retail Channels
The company says it intends to expand across both products and retail channels in the coming years, with new gut-directed products aimed at a growing mainstream audience.
