DS-01 Daily Synbiotic

DS-01 is Seed's flagship synbiotic. Two capsules a day deliver 24 named probiotic strains totaling 53.6 billion AFU, plus 400 mg of Indian pomegranate extract, a polyphenol prebiotic rather than a fiber. The capsule-in-capsule "ViaCap" design is meant to shield the bacteria from stomach acid, and Seed states that viability and potency are guaranteed through the listed expiration date when the product is stored at room temperature (up to 79°F).

What separates DS-01 from most probiotics is that the finished formula, not just its individual strains, has been tested in people. A decentralized, double-blind trial published in Nutrients in 2026 randomized 350 generally healthy adults with self-reported bloating to DS-01 or placebo for six weeks. The DS-01 group reported less bloating and gas, less abdominal discomfort and better regularity. Seed funded the study, two authors are Seed employees and the outcomes were self-reported, so we treat it as promising rather than definitive. A smaller 91-day trial (32 people) found shifts in microbiome markers such as urolithin A and butyrate.

The label names every strain with its designation, but groups them into four blends, so you can't see how much of each strain you get. At $49.99 a month on Seed's subscription (about $1.67 a day), or $59.99 for the starter jar, it costs several times more than mainstream probiotics.

Buyers most often report easier regularity and less bloating after a few weeks. The most common complaints are the price, mixed digestive results (including constipation for some) and occasional headaches. Seed suggests starting with one capsule a day for the first three days if you have a sensitive stomach.
