Immune System and Probiotics

They estimate that there is 100 trillion bacteria living in your gut and is the human equivalent of an environmental ecosystem. Our personal microbe population is losing its diversity and threatening our health.   Your immune system, at least 70% of which is located in your gut - relies on the makeup of your intestinal bacteria.

Probiotic organisms switch on the body's protective signaling mechanisms:
  • Boost populations of immune cells that play a role in tumor inhibition.
  • Upregulate immune cytokines to battle the early stage of cancer or other threats.
  • Suppress bacteria that convert pro-carcinogen molecules into carcinogens.
  • Suppress the inflammatory response as the cancer or infection threat fades.
