Your liver clears Tylenol at its own pace—fast, intermediate, or slow. If you're a slow processor, standard doses linger longer than they should, and "take two every four hours" might be too much for your system. This guides safe dosing and prevents accidental overload.

Lower genetic output is common and responds well to precursors like NAC, glycine, and selenium. This is often the missing piece for people who "do everything right" but still feel run down.
