I was pleasantly surprised by the extraordinary difference between TeraGanix EM-1 and other soil-based microorganisms' products I had previously administered my daughter -who suffers from gastrointestinal problems. In the span of three days, she started eating normally. She had been, literally, forced to eat for over a month. TeraGanix EM-1 has re-populated her gut which has normalized her appetite. I am really grateful to have found this great product.
