About the microgram
The microgram gained importance in modern pharmacology and toxicology, where substances are active at extremely small doses.
In everyday use the microgram appears in vitamin dosing (like B12 and D), hormone measurements, and trace element analysis. As a point of reference: the recommended daily intake of vitamin B12 is 2.4 micrograms.
