Do I need to stop taking my supplements or medications before the test?
Not necessarily. You should follow whatever regimen that you wish to continue to follow to determine your health status on the regimen. For example, I continue to take my vitamins prior to getting tested because I want to know my nutritional status on them as they are a part of my health lifestyle.. If you wanted to know your nutritional or health status off of supplements then you will want to stop prior to the test, but if you want to know your health status under your current health lifestyle then you should continue your normal regimen.
