Hi funrun73. That is a great question and it confuses lots of people.
Essentially there is confusion around the "Daily Values" found on food labels and the RDA graphs in FitDay. The US government uses Daily Values for the values on a food label. These values are picked by the government to be useful without knowing the person's age and gender. FitDay takes those numbers and turns them into an amount ( for example 100% of Vitamin C becomes 60mg).
FitDay displays RDA charts in our reports.Your RDA for a nutrient is a different government standard that takes into account things like your age and gender. These are things that the label couldn't take into account. So while the DV was 100%, your personal RDA may be 110% because you need less due to your age and gender.
This can be confusing, but I hope this helps
