 So these class two nutrients must be present at 80% of more of the declared value. So let's take vitamin C as an example. Let's say that the nutrition label says there's six milligrams per serving of vitamin C naturally occurring in the food. When the product is tested, as long as there's at least 4.8 milligrams, which is 80% of six, then the label is in compliance. So the vitamin C could be lower than what's on the actual label.
