Tolerable Upper Intake Levels (UL) are specifically designed to indicate the maximum daily intake of a nutrient that is unlikely to cause adverse health effects in almost all individuals within a specific age and gender group. The primary purpose of establishing ULs is to help prevent toxicity and ensure that individuals do not exceed safe consumption levels that could lead to harmful effects.

This is particularly important for nutrients that can be toxic when consumed excessively, such as vitamins A and D, or minerals such as iron and zinc. ULs provide guidance for both supplementation and fortified food sources, ensuring individuals can make informed choices regarding their nutrient intake without risking their health.

In contrast, other options refer to different nutritional concepts. The concept of the lowest daily nutrient intake levels pertains more to Adequate Intakes (AI). Average daily requirements for nutrients are covered under Recommended Dietary Allowances (RDA) instead. Finally, the recommended daily allowance encompasses general recommendations for nutrient intake rather than indicating specific upper limits for safety.
