Adequate Intake

Adequate Intake (AI) is a recommended daily level of a nutrient set by health authorities when there isn’t enough evidence to establish a specific Recommended Dietary Allowance (RDA). It aims to ensure people get enough of a nutrient for overall health and proper body function. AI is based on observed intakes of healthy people and may be adjusted as new research becomes available. Think of it as a general guide to help maintain good health, especially when scientific data isn’t sufficient to determine an exact requirement.
