The dose makes the poison inferred

A reported mouse iv LD50 for Ammonium bicarbonate is 245 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:

17.1 g
a median lethal dose scaled to 154 lb (17,150 mg)

“The dose makes the poison” is a cross-species estimate shown as neutral science, not a threshold anyone should act on. Real toxicity depends on the person, not body mass alone.
