                                While the Tolerable Upper Intake Level (UL) for vitamin C is 2,000 mg for adults, consuming a daily 1000 mg dose may still cause side effects in some individuals. The risks vary based on an individual's health and sensitivity, making it important to understand the potential adverse reactions before supplementing.
