La-14® introduction

L acidophilus La-14® is a lactic acid bacterium of human origin that has been documented in over 50 scientific studies, including 18 clinical trials.  Preclinical studies have shown La-14® can impact both the innate and adaptive immune system.1,2  These effects and antipathogenic activity are thought to be potential mechanisms behind the efficacy of La-14® combined with HN001™ in women’s health.3,4 In addition, these two strains together have been shown to support healthy vaginal colonization through oral supplementation.5
