Ultimate Flora Vaginal Support Formula was formulated to help maintain a healthy balance of vaginal and urinary tract bacteria. The difference with Ultimate Flora Vaginal Support is the 45 billion Lactobacilli, plus the 9 carefully chosen strains and the enteric coating. Ultimate Flora Vaginal Support contains among the highest concentrations of vaginal support probiotics available in one capsule. To consume 45 Billion Lactobacilli bacteria per day, you would have to take multiple capsules of most probiotic products. With Ultimate Flora Vaginal Support, all you need is one capsule. The 9 strains of probiotics were chosen for their prevalence in a healthy vaginal and urinary tract, as well as their clinically proven effectiveness when taken orally. Each capsule is enteric-coated to ensure the delivery of the probiotics directly to the intestines. Non-coated: Capsule dissolves in stomach, probiotics can be destroyed. Ultimate Flora Vaginal Support: Capsule dissolves in intestine for better delivery of probiotics. Ultimate Flora Vaginal Support Formula contains 50 Billion active probiotic organisms, which are natural residents of the healthy urogenital tract (vagina and urinary tract). Ultimate Flora Vaginal Support Formula contains 45 billion Lactobacilli and 5 billion Bifidobacteria. Lactobacilli are the most prevalent beneficial bacteria found in the urogenital tract, with lesser numbers of Bifidobacteria. Lactobacilli produce compounds and acids that help to fight the growth of harmful bacteria and yeast. The urogenital tract is second only to the colon in the number of bacterial residents, and many people experience yeast infections and urinary tract issues when the beneficial bacteria become unbalanced. The high concentration of probiotics in Ultimate Flora Vaginal Support Formula is designed to help maintain a healthy balance of vaginal and urinary tract bacteria.
