Bacillus Subtilis HU58 is a friendly bacterial spore that

was discovered in a healthy human gut at the University of

London. HU58 is an incredibly rugged spore that can

withstand extreme pH levels, high temperatures,

dehydration, antibiotics, pressure, radiation, and even the

harsh environment of the digestive tract. It can also

produce over 12 targeted antibiotics of its own, which

makes it particularly effective at balancing gut flora.*
