Define Recommended Dietary Allowance for riboflavin (RDA)?

Several nutritional and physiological factors govern riboflavin requirements. Negative nitrogen balance reduces riboflavin requirements and excretion. Physical activity reduces urinary riboflavin excretion. Hence, the dietary requirement is increased by exercise and increased physical activity.

Therefore, the RDA for individual intake follows the similar pattern as for thiamin. RDI for riboflavin for adults are 0.6 mg/ 1000 Kcal, i.e. for adult males, the requirements are 1.4 mg/day while for adult females, it is 1.1 mg/day and increase up to 1.3- 1.4 mg/day during pregnancy and lactation. Compare this Indian requirement with the FAOIWHO 2004 recommendations presented in Table. How do the requirements compare?
