Committed to PotencyPotent probiotic
formulations guaranteed to maintainlabeled CFU counts through expiration.
For us, potency isn't a number —it's a principle. Every VSL®
Probiotics formulation is developed with meaningful levels of live
bacteria, manufactured under controlled conditions, and verified
to maintain the labeled CFU count through expiration when stored
as recommended.
Potency matters because probiotic function depends on both the
quantity and vitality of live organisms that reach the gut. Even
modest loss over time can affect performance,which is why every
VSL® Probiotics product is designed and tested to deliver
consistent strength from first dose to last.
Designed for Viability
Carefully designed formulations that help safeguard livebacteria from production to delivery.
For probiotics to work, live microorganisms must survive both
storage and digestion to reach the gut intact. Every VSL
Probiotics formulation is developed with this in mind 一 combining
carefully selected strains, stability-enhancing formulation design,
and packaging to maintain viability from manufacturing through
expiration.
VSL#3® is maintained under strict cold-chain conditions-
refrigerated throughout production, storage, and shipping 一 to
help preserve live strains at their intended strength.VSL4®
products are shelf-stable and formulated with acid-resistant
capsules that help protect probiotic bacteria until they reach the
intestinal tract.
Science-Led Strain Selection
Thoughtfully formulated with complementary probiotic
strains chosen for function and purpose.
Our formulations are grounded in science. Each strain is selected
for its documented characteristics and ability to contribute
meaningfully to a balanced microbiome. This approach draws on
years of probiotic research— building on well-studied
formulations and evidence-backed strains to create products
designed for specific microbiome needs.
Across the VSL® Probiotics family, every formulation follows the
same principle: science guides each step,from strain selection to
finished product. This consistent, evidence-based process ensures
reliability and quality across the brand's entire portfolio.

credibility, and professional trust.

long trusted by healthcare professionals for its quality and
reliability. That foundation continues to guide how we develop
