trace elements
Tiny nutritional necessities
Trace elements are chemical elements required in tiny quantities for biological processes.
In nutrition, trace elements like iron, zinc, and iodine are essential for health but needed only in minute amounts—too little causes deficiency, too much causes toxicity.
In geology and chemistry, trace elements are those present in a substance at very low concentrations, useful for identifying origins or contamination.
