What is a good Magnesium, RBC level?

BioForge works to an optimal range rather than the lab's reference flag. For Magnesium, RBC that is 5.5–6.5 or Lab range 3.7–7.0, measured in mg/dL — not serum. A result inside the lab's normal range can still sit outside the range where most people feel and function well.
