Microbiome science company Seed Health is launching nationwide Monday at Costco, offering its flagship DS-01 Daily Synbiotic to store members.

DS-01 is formulated with 24 scientifically selected probiotic strains and a prebiotic. As reported in a study published in Nutrients, it can improve regularity, reduce bloating and alleviate gas. DS-01’s proprietary capsule-in-capsule ViaCap technology is engineered to protect the probiotic strains through digestion and release them in the colon.

Seed creates clinically validated innovations for gut and whole-body health based on research to advance microbial interventions, enhance biodiversity and help restore ecosystems impacted by human activity, a company press release stated.

“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.”

Besides Costco, Seed has established an omnichannel presence across Amazon, Target, Sprouts Farmers Market and Erewhon, and DS-01 is the leading digestive health probiotic sold at both Target and Amazon, according to market research firm SPINS. Seed’s revenue has grown 13 times in five years while remaining profitable.

Research beyond the gut

Seed is also known for developing synbiotics that address concerns outside of the gastrointestinal tract. Seed launched VS-01 in 2024 and a clinical study showed a slow-release vaginal tablet of the synbiotic led to an optimal vaginal microbiome.

The synbiotic was also associated with a decrease in the abundance of Candida, the most common source of vaginal yeast infections.

In 2025, Seed expanded its portfolio beyond DS-01 to include what the company termed as co-biotics. Among the products launched was a multivitamin, DM-02, providing 100% of the daily value of 20 essential vitamins and minerals in bioavailable and bioactive forms. The multivitamin also contained a cellular energy complex. Co-biotics AM-02 Energy + Focus and PM-02 Sleep + Restore were a caffeine-free formulation and a rapid- and slow-release melatonin, respectively.

“We can confidently say that the new products have been developed to the same standards as DS-01,” Bowtell said at the time.

Moving forward, Seed has positioned itself to introduce its next generation of microbiome-targeted products with greater reach and impact, planning to expand across products and retail channels in the years ahead. The goal is to bring new gut-directed innovations to a growing mainstream audience.
