Micronutrients are nutrients such as vitamins and minerals required by organisms in varying quantities throughout life to orchestrate a range of physiological functions to maintain health. [1] [2] The following is a list of micronutrients used by various living organisms. For human-specific nutrients, see Mineral (nutrient).
[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]
Micronutrients are vitamins and minerals the body requires in only small amounts. There are two major types: water-soluble and fat-soluble. Water-soluble nutrients, such as B vitamins and vitamin ...
Vitamins and minerals are essential to the proper functioning and maintenance of the human body. [114] There are 20 trace elements and minerals that are essential in small quantities to body function and overall human health. [114] Iron deficiency is the most common inadequate nutrient worldwide, affecting approximately 2 billion people. [115]
Hence the name micronutrients. “But don't let the micro-doses make you think they're not important,” says King. Micronutrients “play critical roles in the body's overall health at a cellular ...
Organic micronutrients are classified as vitamins, and inorganic micronutrients are classified as minerals. Nutrients can also be classified as essential or nonessential, with essential meaning the body cannot synthesize the nutrient on its own. [6] Nutrients are absorbed by the cells and used in metabolic biochemical reactions.
The human diet can vary widely. In nutrition, diet is the sum of food consumed by a person or other organism . [ 1 ] The word diet often implies the use of specific intake of nutrition for health or weight-management reasons (with the two often being related).
The four organogenic elements, namely carbon, hydrogen, oxygen, and nitrogen , that comprise roughly 96% of the human body by weight, [7] are usually not considered as minerals (nutrient). In fact, in nutrition, the term "mineral" refers more generally to all the other functional and structural elements found in living organisms.
