Essential nutrients

Minerals (also referred to as dietary minerals, mineral nutrients or dietary elements) are the chemical elements required by people excluding vitamins and carbon, hydrogen, nitrogen, and oxygen. The term "minerals" is used even though the minerals are more chemical elements rather than actual minerals.

An essential nutrient is a nutrient required for normal human body function that either cannot be synthesized by the body at least in the required amounts.

FDA supplies daily values for vitamins and minerals

Recommended intakes of nutrients vary by age and gender and are known as Recommended Dietary Allowances (RDAs) and Adequate Intakes (AIs). However, one value for each nutrient, known as the Daily Value (DV), is selected for the labels of dietary supplements and foods. A DV is often, but not always, similar to one's RDA or AI for that nutrient. DVs were developed by the U.S. Food and Drug Administration (FDA) to help consumers determine the level of various nutrients in a standard serving of food in relation to their approximate requirement for it. The label actually provides the %DV so that you can see how much (what percentage) a serving of the product contributes to reaching the DV.
