RDA values do not add up
This morning I put in 3 items for my breakfast which had B12 %RDAs of 0, 0 and 50%. The total for the day is showing 130% of B12. Should it not be 50%?
I checked for zinc as well and the total was also different that the sum of the 3 items.
Am I just really bad at math, or is something off here?
