Probiotic Yeast Support™
Probiotic Yeast Support™ Function
Supports Healthy Yeast Balance*
What Does Probiotic Yeast Support Do?

Jarrow Formulas® Probiotic Yeast Support™ provides clinically documented probiotic strains shown to lower vaginal pH and support a healthy balance of beneficial yeast and bacteria.* Kluyveromyces marxianus B0399 (formerly Kluyveromyces fragilis B0399), a lactic acid-producing yeast, and Lactobacillus crispatus, a key vaginal Lactobacillus species, support a healthy microflora, including beneficial yeast over undesirable yeast.*

Female physiology and genetics, combined with lifestyle and hormonal changes throughout life, often affect women's immunity and digestive health. Jarrow Formulas®  Probiotic Yeast Support™ contains probiotics to support healthy yeast balance.*

Better Stability of Probiotics
Jarrow Formulas® Probiotic Yeast Support™ is packaged in an Activ-Vial™ moisture-controlled desiccant bottle to help enhance the stability of probiotics.
