Nutrient. A nutrient is a substance used by an organism to survive, grow and reproduce. The requirement for dietary nutrient intake applies to animals, plants, fungi and protists. Nutrients can be incorporated into cells for metabolic purposes or excreted by cells to create non-cellular structures such as hair, scales, feathers, or exoskeletons.
Magnesium occurs typically as the Mg 2+ ion. It is an essential mineral nutrient (i.e., element) for life [1][2][3][4] and is present in every cell type in every organism. For example, adenosine triphosphate (ATP), the main source of energy in cells, must bind to a magnesium ion in order to be biologically active.
Your body also makes vitamin D from sunlight, and your gut bacteria make some vitamin K. By comparison, vitamin supplements contain vitamins in a capsule, tablet, liquid, gummy, or powder form ...
