Tolerable Upper Intake Levels (UL)

Tolerable Upper Intake Levels (UL) are the maximum daily amounts of a nutrient that are unlikely to cause harm for most people. They are set based on scientific evidence to help prevent adverse effects from consuming too much of a nutrient, especially from supplements or fortified foods. While it’s important to get enough nutrients for good health, exceeding the UL can lead to negative side effects or toxicity. ULs serve as a safety guideline for individuals, health professionals, and policymakers to ensure nutrient intake remains within a safe range.
