But measuring floating nutrients in your liquid serum is like looking at the paint on a house to see if the plumbing works inside. After reviewing over 40,000 advanced intracellular vitamin lab panels, the truth is clear: intracellular glutathione vs serum levels tell two entirely different stories.
