Tolerable daily intake is a phrase used to describe the maximum amount of a substance that can be consumed by an individual without causing harm. However, there are several synonyms for this phrase that can be used interchangeably. One of the most commonly used is acceptable daily intake, which is often used in the context of food additives and other substances that are intentionally added to food.
