These values, which vary by age and sex, include:</p><ul><li><strong>Recommended Dietary Allowance (RDA)</strong>: The average daily level of intake that is enough to meet the nutrient needs of nearly all (97% to 98%) healthy people. An RDA is an intake level based on scientific research evidence.</li><li><strong>Adequate Intake (AI)</strong>: This level is established when there is not enough scientific research evidence to develop an RDA.
