The daily nutrient intake recommended for optimal health.
The average daily intake level of a nutrient sufficient to meet the needs of nearly all healthy individuals in a specific age and gender group.
The Recommended Daily Allowance (RDA) is a nutrient reference value established by nutrition experts based on scientific evidence of requirements for different population groups. It represents the intake level that meets the nutritional needs of 97-98% of healthy individuals in a particular age and sex group. The RDA varies by nutrient, age, sex, and life stage (pregnancy, lactation, etc.). Food labels often reference RDA values to help consumers understand whether products contribute meaningfully to daily nutrient goals. Different countries may use equivalent terms like RDI (Reference Daily Intake).

Use RDA values as general guidance, but remember individual needs may vary based on health status, activity level, and life stage. Focus on meeting RDA through a varied, balanced diet when possible. Consult healthcare providers for personalized recommendations.
