Tolerable Upper Intake Level

The Tolerable Upper Intake Level (UL) is the maximum daily amount of a nutrient that is unlikely to cause harmful effects for most people. It helps guide safe consumption, preventing potential health problems from consuming too much of a nutrient, such as vitamins or minerals. While getting enough of a nutrient is important, exceeding this level regularly may lead to adverse health issues. The UL is determined through scientific research and applies to the general population, although individual needs and sensitivities can vary.
