As a hormone testing lab, ZRT understands the importance of a well-balanced endocrine system in maintaining overall health. Hormone balance is achieved through multiple feedback mechanisms, and when any part of the system is thrown out of whack by forces beyond its control, there is a knock-on effect on the rest of the body systems that are under endocrine control.

If you want to improve brain health, you need to make sure it gets enough oxygen, nutrition, and anti-oxidant support so that’s the unifying theme.

"You have a 5-inch tumor in your chest" were the words spoken from a friend and radiologist as we both stared bewildered at my chest X-ray, following a host of side effects I'd been having for weeks.

As I looked at the X-ray film in amazement, my thoughts quickly changed to frustration and anger as I realized my behaviors and actions played a pivotal role in creating my disease—non-Hodgkin's lymphoma.
