What does the Adequate Intake (AI) refer to?

Adequate Intake (AI) refers to a recommended level of nutrient intake that is assumed to be sufficient to meet the needs of most individuals in a specific age and gender group. The AI is established when there is not enough scientific evidence to determine a precise Recommended Dietary Allowance (RDA) for a nutrient. It is based on the observed or experimentally determined approximations of nutrient intake by a group of healthy people. Thus, AI serves as a guideline to ensure individuals receive adequate nutrition to promote health and prevent deficiencies. This makes it particularly important for nutrients that are essential for various bodily functions and overall health maintenance.
