Seed DS-01 Daily Synbiotic

“The probiotic that actually survives your stomach acid.”

$50/mosupplement

Most probiotics die before they reach your gut. Seed solved this with their patented ViaCap delivery system — a capsule-within-a-capsule that protects 24 clinically studied strains through stomach acid. This is what happens when real scientists (not marketers) make a supplement. Four published clinical trials. Peer-reviewed. No CFU inflation games.

Peer-reviewed research, not just marketing claims with celebrity endorsements

Key ingredients

24 probiotic strains (53.6 billion AFU)Pomegranate extract (prebiotic)Pine bark extract (prebiotic)

The science

The DS-01 formulation has been studied in 4 clinical trials showing improvements in gut barrier integrity (reduced zonulin), digestive comfort, microbiome diversity (Shannon index), and cardiovascular markers. The prebiotic component (polyphenols) feeds existing beneficial bacteria while the probiotic strains colonize.

However, the degree to which such synbiotic formulations improve probiotic strain functionality in humans has not been tested systematically. Our goal was to use a randomized, double-blind, placebo-controlled, parallel-arm clinical trial in obese humans to compare the ecological and physiological impact of the prebiotic galactooligosaccharides (GOS) and the probiotic strains Bifidobacterium adolescentis IVS-1 (autochthonous and selected via in vivo selection) and Bifidobacterium lactis BB-12 (commercial probiotic allochthonous to the human gut) when used on their own or as synbiotic combinations. After 3 weeks of consumption, strain-specific quantitative real-time PCR and 16S rRNA gene sequencing were performed on fecal samples to assess changes in the microbiota. Intestinal permeability was determined by measuring sugar recovery in urine by GC after consumption of a sugar mixture. Serum-based endotoxin exposure was also assessed. Results: IVS-1 reached significantly higher cell numbers in fecal samples than BB-12 (P < 0.01) and, remarkably, its administration induced an increase in total bifidobacteria that was comparable to that of GOS. Although GOS showed a clear bifidogenic effect on the resident gut microbiota, both probiotic strains showed only a non-significant trend of higher fecal cell numbers when administered with GOS. Post-aspirin sucralose:lactulose ratios were reduced in groups IVS-1 (P = 0.050), IVS-1 + GOS (P = 0.022), and GOS (P = 0.010), while sucralose excretion was reduced with BB-12 (P = 0.002) and GOS (P = 0.020), indicating improvements in colonic permeability but no synergistic effects. No changes in markers of endotoxemia were observed.

How to use

Take 2 capsules daily on an empty stomach (morning works best). First week may cause mild bloating as microbiome adjusts — this is normal and resolves within 5–7 days.

Who it's for

Anyone serious about gut health, immune function, or skin clarity. Especially if you've tried probiotics before and 'didn't notice anything' — delivery matters more than strain count.
