[1] [2] The following is a list of micronutrients used by various living organisms. For human-specific nutrients, see Mineral (nutrient).
RDA for lactation is 12 mg/day. For infants up to 12 months, the RDA is 3 mg/day. For children ages 1–13 years, the RDA increases with age from 3 to 8 mg/day. As for safety, the IOM sets Tolerable upper intake levels (ULs) for vitamins and minerals when evidence is sufficient. In the case of zinc the adult UL is 40 mg/day (lower for children).
Plants tend not to use vitamins, although minerals are required. [8] [17] Structure of the Mn 4 O 5 Ca core of the oxygen-evolving site in plants, illustrating one of many roles of the trace mineral, manganese. [18] Some seven trace elements are essential to plant growth, although often in trace quantities. [citation needed]
Calcium, sodium, potassium, magnesium, and chloride ions, along with phosphorus and sulfur, are listed with macronutrients because they are required in large quantities compared to micronutrients, i.e., vitamins and other minerals, the latter often described as trace or ultratrace minerals.
