Recommended Daily Allowance (RDA)

The Recommended Daily Allowance (RDA) is the average amount of a nutrient, such as vitamins or minerals, that most healthy people need each day to stay well and prevent deficiencies. These guidelines are based on scientific research and help individuals plan their diets to ensure they get enough essential nutrients. RDAs vary by age, sex, and life stage, and they aim to promote optimal health rather than maximum intake. They serve as useful reference points for maintaining proper nutrition, though individual needs may differ slightly.
