RDA 

Recommended Daily Allowance.

Term used to explain the amount recommended on a daily basis for vitamins and other dietary supplements.

Look on the side of any food product at the nutritional information, and somewhere in the little box should be the "RDA" on any of the recommended percentages of vitamins, minerals and other contents of that food.
