The dose makes the poison inferred
A reported rat oral LD50 for Caprylic acid is 1,410 mg/kg, the dose lethal to half the animals tested. Scaled by body mass alone:
98.7 g
a median lethal dose scaled to 154 lb (98,700 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.
