Please do NOT rephrase or reword or rewrite the troubling sentence.
Are there any verbs as a single word that equates to fall short (of)
(and thus is an antonym of 'exceed') ?
Context: In this question of mine at Health SE, I want to stress (pun intended) that even calcium supplement doses FAR below the daily maximum, may still harm the heart. 'Fall short of' implies that you're only hovering a little below the maximum; so I need a more extreme word.
Are calcium supplements harmful, even if you fall short of the maximum dose?
