The dose lens
“The dose makes the poison.” Pick a food, sweetener or scent molecule and a body weight to see its reported animal LD50 scaled by body mass alone. It is neutral science and an estimate, not a threshold anyone should act on, and it gives no advice about any dose.
The dose makes the poison inferred
A reported rat oral LD50 for Caffeine is 192 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:
An LD50 is an animal study measurement, not a dose for a person. “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.
