Digestive and Women's Health7 Targeted Strains9.8 Billion CFU†Dietary SupplementMaintains Microbial BalanceSupports Microbial BalanceSupports Women's HealthScience-Backed Quality Since 1969 Swanson FemFlora is a probiotic supplement for women that now features multiple lactobacilli species (compared to just two probiotic strains in the old formula) to support the flora of the mouth, gastrointestinal tract and vagina. The lactobacillus strains have been studied for their role in supporting and maintaining vaginal health. These strains may protect the urogenital tract by excreting biosurfactants that help keep the tissues clean and healthy. Another strain in this formula, L. plantarum, appears to be a predominant strain in both oral and intestinal mucosa. Studies show that it competes with other bacteria and therefore may influence intestinal and systemic immunity. More and more people are discovering the connection between intestinal health and overall health, and probiotics can play a huge role in maintaining both. FemFlora is designed specifically for the female body. †Contains total of 9.8 billion CFU (colony forming units) when manufactured, and provides an effective level of bacteria until at least the "best by" date.
