Why Primal Defense?
Primal DefenseĀ® is the only probiotic containing 12 species of hardy beneficial microorganisms in the form of the HSO Probiotic Blend. The ability of the probiotics in Primal DefenseĀ® to support the normal healthy flora balance in the gut is not based solely on CFU count, but also on their ability to withstand harsh conditions in the digestive tract such as stomach and bile acids.
