Pairs with

S. Boulardii is a yeast probiotic — structurally different from traditional bacterial strains

Traditional probiotic supplements contain bacterial strains that can be disrupted by antibiotics, stomach acid, and changes in gut environment. S. Boulardii is a yeast-based probiotic — structurally different, and uniquely resilient. It works alongside your existing gut flora rather than competing with it, supporting digestive balance in conditions where bacterial probiotics may struggle.*

  • Yeast-based — may remain viable even alongside antibiotic regimens*
  • Complementary — works alongside your existing microbiome
  • Resilient — formulated to remain viable through normal stomach acid and bile environments*
