What does it mean when a UL does not exist for a nutrient?
What does it mean when a UL does not exist for a nutrient?
Developed in part as a response to the growing usage of dietary supplements, ULs indicate the highest level of continuous intake of a particular nutrient that may be taken without causing health problems. When a nutrient does not have any known issue if taken in excessive doses, it is not assigned a UL.
What does the UL upper tolerable limit of a nutrient represent?
Lastly, the Tolerable Upper Intake Level (UL) is the highest level of a daily nutrient intake that will most likely present no risk of adverse health effects in almost all individuals in the general population (see table).
What if there is no Tolerable Upper Intake Level?
The fraction of the population consistently consuming a nutrient at intake levels in excess of the Tolerable Upper Intake Level (UL) is potentially at risk of adverse health effects. If no discernible portion of the population consumes the nutrient in excess of the UL, no public health risk should exist.
Why is there no Tolerable Upper Intake Level set for energy nutrients?
Tolerable Upper Intake Level (UL): the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all individuals in the general population. As intake increases above the UL, the risk of adverse effects increases.
What does the absence of a Tolerable Upper Intake Level UL for a specific nutrient indicate?
BACKGROUND. The Tolerable Upper Intake Level (UL) refers to the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all individuals in the general population. As intake increases above the UL, the risk of adverse effects increases.
What is the tolerable upper intake level or upper limit?
If the nutrient intake increases above the Tolerable Upper Intake Level or UL, the risk of ill-effects on the human body may also increase. In fact, the term’ tolerable intake’ itself indicates that any nutrient intake that crosses this level can pose a risk to the human health. Any intake within this limit can be ‘tolerated’ biologically.
What happens when nutrient intake exceeds the tolerable level?
If the nutrient intake increases above the Tolerable Upper Intake Level or UL, the risk of ill-effects on the human body may also increase. In fact, the term’ tolerable intake’ itself indicates that any nutrient intake that crosses this level can pose a risk to the human health.
Which is the highest level of nutrient intake?
NOTE: A Tolerable Upper Intake Level (UL) is the highest level of daily nutrient intake that is likely to pose no risk of adverse health effects to almost all individuals in the general population. Unless otherwise specified, the UL represents total intake from food, water, and supplements.
How is an ul related to total intake?
It helps in understanding if any adverse effects are associated with the total intake. If the ill-effects are associated only with the intake of fortified foods and supplements, then the UL is based on nutrient intake from these food sources and not on the total intake.
If the nutrient intake increases above the Tolerable Upper Intake Level or UL, the risk of ill-effects on the human body may also increase. In fact, the term’ tolerable intake’ itself indicates that any nutrient intake that crosses this level can pose a risk to the human health. Any intake within this limit can be ‘tolerated’ biologically.

Which is the highest level of Reference Intake?
The final set of dietary reference intake values is the Tolerable Upper Intake Levels (ULs). This is the highest level for nutrients that nearly all healthy individuals in a particular group can reach without adverse effects.
