This is the maximum amount of a nutrient that can be consumed without adverse effects. It is not a target figure; it is an upper limit.
If the nutrient does not have a tolerable upper intake level it means it does not have a maximum amount of that can be taken before damage occurs. Any nutrient that has a tolerable upper intake level is one you can overdose on or take too much of the nutrient. Much like potassium which can be deadly but vitamin c does not have an upper intake level.
This is the maximum amount of a nutrient that can be consumed without adverse effects. It is not a target figure; it is an upper limit.
If a nutrient does not have a Tolerable Upper Intake Level (UL), it indicates that there is insufficient evidence to determine a level at which adverse effects may occur. This could mean that the nutrient is generally considered safe at high intakes or that potential risks have not been adequately studied. It doesn't imply that there are no risks associated with excessive intake; rather, caution should be exercised as high doses could still pose unknown risks.
What does tolerable upper intake level mean?
The TUL (Tolerable uptake level) for sodium is 2, 300 g/day
It represents the maximum daily amount of a nutrient that appears to be safe for the majority of healthy people. (beyond this level there is a health risk)
10mg
45mg
Tolerable Upper Intake Level
1 teaspoon
the absence of a ul for a nutrient does not imply that it is safe to consume any amount, however. it means only that insuficent data exist to establish a value
