details By microbiomelabs MegaSporeBiotic™ is a 100% spore-based, broad-spectrum probiotic shown to maintain healthy gut barrier function. This unique all-spore formula effectively RECONDITIONS the gut by promoting microbial diversity and maintaining key health-promoting, commensal gut bacteria. MegaSporeBiotic™ boasts a 5-year shelf-life, does not require refrigeration, and maintains a healthy gut microbiome.** MegaSporeBiotic is a probiotic blend of 5 Bacillus spores that have been shown to maintain healthy gut barrier and immune function. The bi-phasic life cycle of the Bacillus spores allows them to remain dormant in harsh environments until they reach more favorable environments like the human gastrointestinal tract. Once inside the large intestine, these dormant spores can change into their active, vegetative forms and begin colonizing in the gut. This unique probiotic blend aims to RECONDITION the gut instead of reseeding with probiotic strains that cannot survive digestion or colonize the gut. MegaSporeBiotic has quickly become a household favorite among health practitioners and consumers alike.
