The beneficial influence of a proper diet on our health has been known since ancient times. Our diet provides a number of compounds that are essential for our health. Although a healthy diet provides a sufficient amount of vitamins and minerals, many individuals regularly take vitamin and mineral supplements hoping to further improve their health and prevent diseases. More than one-third of adults in high-income countries regularly take these supplements.1
