Ultra Hardy-Strain Probiotic

  • NEW! Nearly indestructible probiotic supplement for high GI survivability
  • 30 billion CFU and 4 carefully selected strains
  • Spore-forming and yeast-based structure

Swanson Ultra Hardy-Strain Probiotic features four strains renowned for their outstanding durability: Saccharomyces boulardii, Bacillus coagulans, Bacillus clausii and Bacillus subtilis. Saccharomyces boulardii is a probiotic yeast with the ability to withstand stomach acidity so it can safely reach the lower GI tract, where it supports immune function and protects the beneficial bacteria that facilitate comfortable digestion. The three Bacillus strains featured in the formula are spore-forming bacteria, which enables them to survive at higher temperatures, eliminating the need for refrigeration and dramatically increasing shelf-life. More importantly, the spores protect the organisms from stomach acids, enabling them to reach the lower GI tract intact. Once there, they become active lactic acid producing probiotics, helping maintain a healthy microbial balance for comfortable gastrointestinal function.


Q: Does Ultra Hardy-Strain Probiotic need to be refrigerated?

A: Refrigeration is not required. Our probiotics are formulated to provide the number of CFU stated on the label. If desired, you may refrigerate after opening to ensure maximum potency.

Swanson products are often marked with a Manufacture (MFG) date rather than an Expiry (EXP) date. Unless specified by an expiry date, products are considered stable at full potency for two years from the MFG date. Exceptions to this include liquids and probiotics which are considered stable for one year from the MFG date.
