A healthy intestinal flora can help to balance harmful organisms, promote digestion, support chemical and hormonal balance, support normal energy levels, and encourage proper immune function. Just as the earth is home to many life forms, the human body harbors a vast internal ecosystem consisting of billions of living microorganisms that coexist peacefully or in conflict. This vast internal ecosystem, or 'human intestinal flora', dramatically influences each person's state of health and well-being, both physical and mental health. With a population exceeding 100 trillion, these microorganisms can exceed the number of cells in the entire body!
