Buy source naturals : dura flora 5 billion cells capsules, 120 caps

Source Naturals DuraFlora ™ is a beneficial probiotic that forms highly resilient structures which create a protective barrier around each cell and support healthy intestinal flora. Preliminary research indicates that these protective barriers survive a variety of adverse environmental conditions and can thrive in a wide pH range. The protective nature of Bacillus coagulans (formerly known as Lactobacillus sporogenes) improves shelf stability of the product and viability of probiotic benefits.
