Patients often ask if they should stop supplements before an intracellular CMA test, and the answer is no. The test measures nutrient status inside your cells over the last 90–100 days, so stopping vitamins right before won’t change the results. At most, you might skip your dose a few hours before the draw, but it’s not necessary—CMA still provides an accurate snapshot of your nutrient levels while you’re on your current routine.
