A. Tolerable Upper Intake Levels

Explanation:

The tolerable upper limit of intake (UL) is the highest level of habitual nutrient intake, which is unlikely to risk any adverse effects on approximately all individuals of a given life stage and gender. When intake increases above UL, the potential risk of adverse health effects increases. It is highly likely to be biologically tolerated, which does not mean that this value is recommended.
