These are shown to the right of all nutrients, vitamins and mineral on the nutrition panel. These percentages represent the percentage of the Reference Daily Intake (RDI) of that nutrient, vitamin or mineral that will be provided by one serving of a particular product based on a 2000 calorie diet. They do not represent what percentage of the product consists of this nutrient, vitamin or mineral, as some have mistakenly believed. These percentages do not necessarily represent your personal daily intake requirements as they may vary from person to person due to health related issues that affect dietary needs.
