Micronutrient
Essential elements required by organisms / From Wikipedia, the free encyclopedia
Micronutrients are essential dietary elements required by organisms in varying quantities to regulate physiological functions of cells and organs.[1][2] Micronutrients support the health of organisms throughout life.[3][4][5]
In varying amounts supplied through the diet, micronutrients include such compounds as vitamins and dietary minerals.[3][6] For human nutrition, micronutrient requirements are in amounts generally less than 100 milligrams per day whereas, macronutrients are required in gram quantities daily.[6] A multiple micronutrient powder of at least iron, zinc, and vitamin A was added to the World Health Organization's List of Essential Medicines in 2019.[7] Deficiencies in micronutrient intake commonly result in malnutrition.[3][8]
