Seed Health is a microbiome science company best known for its DS-01 Daily Synbiotic, a probiotic and prebiotic supplement sold on a subscription basis directly to consumers, along with other gut and women's health products developed with academic research partners. The brand positions itself at the science-forward end of the wellness supplement market rather than as a mass retailer. There's no Seed co-brand credit card, so a subscription order is best charged to a general online shopping or flat-rate cashback card.
