These values, which vary by age and sex, include:</p><ul><li>Recommended Dietary Allowance (RDA) -- 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>Adequate Intake (AI) -- This level is established when there is not enough scientific research evidence to develop an RDA.
