Futurebiotics Longest Living Acidophilus includes potent Lactospore. Delivering viable live probiotics to the intestinal tract is a formidable technical challenge. Lactospore is a naturally microencapsulated sporiferous preparation of Bacillus coagulans that is proven to deliver viable lactobacilli to the intestine. It is room-temperature stable and highly resistant to the action of heat, gastric acids and bile. In addition, Lactobacillus acidophilus and rhamnosus along with Bifidobacterium longum are included, which together with Lactospore provides over 1 billion organisms per capsule and supports healthy intestinal flora balance.
