Trace minerals are those required in amounts less than 100 mg/day, and the AI for this mineral is 30 mg/day. Therefore, it is classified as a trace mineral. Major minerals are required in amounts greater than 100 mg/day, nonessential minerals are not necessary for human health, and possible essential minerals are those where the research is still inconclusive.
